  1-2  Tips and Techniques









  CHAPTER 2.  INSTALLATION CONSIDERATIONS
  _______________________________________





  This chapter describes installation information you might need to consider
  before, during, or immediately after installation; including:

  o   Upgrading from another operating system
  o   Reformatting and partitioning the hard disk
  o   Using non-IBM devices, such as a Logitech** mouse
  o   Handling problems during installation.


  UPGRADE VERSION OF OS/2 2.0
  ___________________________

  The upgrade version of OS/2 2.0 (for DOS, Windows,** and OS/2 1.x) is
                                                                  _
  slightly different from the full-purchase-price version of OS/2 2.0.  You
  must have an operating system installed on your hard disk before you can
  install the upgrade version.

  If you formatted your hard disk before you attempted to install the upgrade
  version, you must put an operating system on the hard disk.  If your previous
  operating system was DOS, start your computer with a DOS diskette, and then
  type the following at the DOS command prompt:

       FORMAT C: /S

  Then proceed with the installation of the upgrade version of OS/2 2.0.

  If installation Diskette 1 in your upgrade package is write protected, turn
                  __________
  the diskette over and locate the black tab at the bottom-right corner.  Slide
  the black tab up so the tab covers the square hole.  If the tab is missing,
  place a piece of tape over the hole.  Covering the hole enables information
  to be written to the diskette during installation.




















  (C) Copyright IBM Corp. 1992                                              2-1









  LIMITED AVAILABILITY VERSION OF OS/2 2.0
  ________________________________________

  If you previously installed the OS/2 2.0 Limited Availability version of OS/2
  2.0 and installed OS/2 2.0 without reformatting, you must update the OS/2
  System Editor and Clipboard Viewer PATH statements in the CONFIG.SYS file.
  Change them so they read as follows:

       \OS2\APPS\E.EXE

       \OS2\APPS\CLIPOS2.EXE

  Also, you might not be able to delete existing program associations.  If this
  occurs, make a copy of the program object that has the associations; then
  discard the original.


  REFORMATTING THE HARD DISK
  __________________________

  Following is information about when you should and should not reformat the
  hard disk while you are installing OS/2 2.0.


  DURING INSTALLATION

  Consider the following when deciding whether or not to reformat the hard
  disk:

  o   If you are installing over any beta version 2.0 except for OS/2 2.0
                                 ___                  ______
      Limited Availability (6.177H), you must reformat.
  o   If you formatted during installation, and the installation failed,
      reformat.
  o   If you did not format during installation and the installation failed,
      try to install again without formatting.  If the installation fails
      again, reformat.  ( Back up any data files you need from the drive on
      which you want to install.)





















  2-2  Tips and Techniques









  AFTER SUCCESSFUL INSTALLATION

  After successfully installing OS/2 2.0, you might want to add or change some
  features.  You do not have to reformat your hard disk and reinstall OS/2 2.0
  to do this, unless you are advised to do so by your IBM dealer or
  representative.  You can add any feature you want by selecting OS/2 SYSTEM,
  SYSTEM SETUP, and then SELECTIVE INSTALL.


  PARTITIONING THE HARD DISK
  __________________________

  It is desirable for OS/2 2.0 to be in a partition by itself, unless you are
  installing Dual Boot.  Then you must have both the DOS and OS/2 operating
  systems on the same partition.

  NOTE:  If you are installing Dual Boot, you must have DOS on the system
         before you install OS/2 2.0.

  The OS/2 partition should be approximately 40 -- 50MB if you want the default
  installation and the swap drive on the same partition.  Because the swapper
  file is based on the size of installed memory, the less memory you have, the
  larger the swapper file, thus you will need a larger partition.

  If you partition the hard disk, you should have at least 2 partitions -- one
  for OS/2 2.0 and one for your data.


  HIGH PERFORMANCE FILE SYSTEM
  ____________________________

  Following is information about the memory requirement for the High
  Performance File System (HPFS) and how to install it.


  CONSIDERATIONS WHEN DECIDING TO USE HPFS

  If you are trying to decide whether to use the HPFS, consider that it takes
  approximately 500KB of system memory.  If your computer has 6MB or less of
  memory, your system performance will be affected adversely.


  ADDING THE HPFS AFTER INSTALLATION

  If you selected either INSTALL ALL FEATURES or INSTALL PRESELECTED FEATURES
  and your computer had 6MB or less of memory, and no partitions formatted for
  HPFS, your computer will not have HPFS support.

  To install HPFS after installation of OS/2 2.0, select SELECTIVE INSTALL in
  the System Setup folder.  In order to use the HPFS, you must format a hard
  disk partition with the following options:

       /FS:HPFS





                                   Chapter 2.  Installation Considerations  2-3









  ADDING DEVICE DRIVER STATEMENTS TO A CONFIG.SYS FILE
  ____________________________________________________

  Some device driver statements might not be copied to your new CONFIG.SYS file
  with a REM statement if you select AUTOMATICALLY UPDATE CONFIG.SYS AND
  AUTOEXEC.BAT during installation.  Instead, select USER EDIT CONFIG.SYS AND
  AUTOEXEC.BAT so you can copy your device driver statements to your new
  CONFIG.SYS file.


  GETTING YOUR MOUSE TO WORK
  __________________________

  Following is information about getting a mouse to work.


  CHANGING THE DEFAULT MOUSE DRIVER

  During installation, do NOT make changes in the Mouse window unless it is
  displayed while Diskette 2 is in the installation drive.  If the Mouse panel
                  __________
  is not displayed for you, OS/2 2.0 has been able to determine the correct
  device driver for your mouse.

  For example, if you have a Logitech PS/2 mouse or serial mouse, series M, the
  installation program will correctly select the PS/2 Style Pointing Device
  driver, not the Logitech Serial Mouse driver.
          ___


  HP MOUSE

  To install an HP** mouse, do the following:

  1.  Accept the default mouse driver during the installation of OS/2 2.0.
  2.  Copy HILMOU.SYS and NOEXBIOS.SYS to the OS2 directory.  (These files are
      supplied by Hewlett-Packard**.)
  3.  Modify your CONFIG.SYS file so it contains the following lines in the
      order shown:

           DEVICE=C:\OS2\NOEXBIOS.SYS
           DEVICE=C:\OS2\HILMOU.SYS
           DEVICE=C:\OS2\MOUSE.SYS TYPE=HILMOU$


  If you do not have the diskette that contains the required files, contact the
  dealer from whom you purchased the mouse.  Or, you can contact
  Hewlett-Packard Company customer service.












  2-4  Tips and Techniques









  LOGITECH MOUSE NOT WORKING AFTER INSTALLATION

  If you have a Logitech PS/2 mouse or a Logitech serial mouse, series M, and
  it does not work after installation, you might have installed the Logitech
  Serial Mouse driver, which is NOT the correct driver.  To select the correct
  mouse driver, use the keyboard to select OS/2 SYSTEM, SYSTEM SETUP, SELECTIVE
  INSTALL, MOUSE in the System Configuration window, and then OK.  These steps
  install the default mouse driver, the PS/2 Style Pointing Device driver, that
  is required for a Logitech mouse.


  LOGITECH MOUSE NOT WORKING AFTER DUAL-BOOT SWITCH FROM DOS

  If your Logitech mouse is not working on a Dual-Boot system after you run DOS
  and switch to OS/2 2.0, your mouse might be running in a mode set by a
  DOS-based mouse device driver.  To correct the problem, type the following at
  the DOS command prompt:

       MOUSE PC

  or

       MOUSE 1200 5B

  This will reset the mouse to a mode that is recognized by OS/2 2.0.  Then
  type the following:

       BOOT /OS2

  OS/2 2.0 should start and your mouse should work.

  You can perform this procedure automatically by creating a batch file for the
  commands you would type:

       MOUSE PC BOOT /OS2

  or

       MOUSE 1200 5B BOOT /OS2

  For information about creating a batch file, refer to the online Master Help
  Index.


  OTHER MOUSE NOT WORKING AFTER DUAL-BOOT SWITCH FROM DOS

  If your mouse works when you first turn on your computer, but it does not
  work when you switch from DOS to OS/2, your mouse might be emulating (acting
                                                             _________
  like) another kind of mouse.  For example, your mouse might be emulating a
  Logitech mouse.  Refer to the documentation that came with your mouse to see
  if it has a command for changing the mode.  If so, try to reset the mouse to
  a mode that is recognized by OS/2 2.0.

  PROBLEMS WITH INSTALLATION
  __________________________

  The following information provides solutions for problems you might encounter
  during or after installation.  They are:

  o   Problems at the LOGO screen
  o   Problems while using specific installation diskettes (they are referenced
      by number)
  o   Messages that are displayed on the screen
  o   Constant beeping while changing diskettes
  o   White screen during or after installation
  o   Early version of BIOS
  o   Patch needed for ZEOS** notebook


  LOGO SCREEN PROBLEMS

  Following are problems that can occur at the LOGO screen during or after
  installation.


  With OAK Video Adapter

  If the installation procedure stops immediately after the LOGO screen is
  displayed, and you have an OAK video adapter, change the video adapter to
  8-bit mode and place it into an 8-bit adapter slot.

  If the problem continues, you can change the OS2LDR file using the DOS DEBUG
  command.  You must have a version of DOS on a DOS diskette or on your hard
  disk.  To change the OS2LDR file, do the following:

  1.  Make a backup copy of installation Diskette 1.  (You can use the DOS
                                         __________
      DISKCOPY command to make the backup.)  Do not change the file on your
                                             ______
      original OS/2 2.0 installation Diskette 1.
                                     __________

  2.  Start DOS from diskette or your hard disk.

      NOTE:  Make sure that DEBUG.COM is on your hard disk.

      Change to the directory that contains the DEBUG.COM file.

  3.  Insert the backup copy of Diskette 1 in drive A.  Type the following at
                                __________
      the DOS command prompt:

           DEBUG A:\OS2LDR

      and press Enter.

  4.  Type:

           4f7c

      and press Enter.  "CD." appears.



  2-6  Tips and Techniques









  5.  Type:

          90

      and press the Spacebar.  "10." appears.

  6.  Type:

           90

      and press Enter.

  7.  To write changes to the file, type:

           W

      and press Enter.

  8.  To end the debug procedure, type:

           Q

      and press Enter.  (If you started DOS from a diskette in drive A, remove
      the backup copy of Diskette 1 from drive A and insert your DOS diskette
                         __________
      and press Enter.  You will see the DOS prompt.)

  9.  Restart the installation of OS/2 2.0 using your modified backup copy of
      Diskette 1.
      __________


  With Future Domain SCSI Controller

  If you have a Future Domain 16xx SCSI controller, you might have installed
                                __
  OS/2 2.0 successfully, but then found a problem the next time you started
  OS/2 2.0.  If the system stopped running with the LOGO screen displayed,
  there might be a conflict with the interrupt settings of your hardware
  devices.  Check all interrupt-request (IRQ) settings on all your hardware
                      _________________
  devices and make sure that each one is using a unique IRQ.  Future Domain
  controllers are shipped from the factory preset to use IRQ5.  However, IRQ5
  is the interrupt that is normally assigned to LPT2.  Also, it is common for
  IRQ5 to be used by sound or communications adapters.  You might not see a
  problem immediately because of interrupt conflicts, but eventually a problem
  can occur.

  Refer to Chapter 9, "Hardware Support" on page 9-1, for more information
  about setting IRQ levels.

      If the installation procedure stops while Diskette 1 is in the diskette
                                                __________
      drive of a non-IBM computer, there might be a problem with the features
      of the hard disk drive controller.  If the controller has on-board disk
      caching, disable the caching.  If the controller can do asynchronous
      memory refreshes, turn off that feature.

  o   DISKETTE 3 PROBLEM

      If the installation program keeps prompting you to insert Diskette 3, you
                                                                __________
      have a 1.44MB diskette drive that can work in either IBM PC/XT(*).  mode
      or IBM PCAT* mode.  You need to change the mode from XT(*) to AT(*) by
      changing the jumper for pin 34 on your 1.44MB diskette drive.  Refer to
      the information that came with your computer or diskette drive to find
      out how to make the change.

  o   DISKETTE 6

      If the installation procedure stops after Diskette 6, the adapter for a
                                                __________
      VGA display might be causing the problem.  If you have a VGA display,
      refer to the Guide to Operations for your VGA adapter.  If the adapter
      has autosense capability, find out how to turn off this feature.  If the
      adapter has a resolution available other than 640x480, make sure the mode
      on the adapter is set to 640 x 480 mode.

  o   NO DISKETTE 16 (3.5-INCH INSTALLATION)

      If you are installing the 3.5-inch version of OS/2 2.0, and the
      installation prompts you to insert Diskette 16, your drive A is not being
                                         ___________
      recognized as a 1.44MB drive.  You must set the Basic Input/Output System
      (BIOS) to recognize drive A as 1.44MB.  Refer to the documentation that
      came with your computer to find out how to do this.


  MESSAGES ON SCREEN

  Following are solutions you can try when you see specific information
  displayed on the screen during installation.  For example, there is something
  you can do if "C0000005" appears when the installation procedure stops.

  2-8  Tips and Techniques









  C0000005

  If "C0000005" appears on the screen the first time you start the system after
  installation, call the OS/2 Technical Support Center at 800-237-5511 and
  request a corrected version of the BVHSVGA.DLL file.


  COUNTRY.SYS File Cannot Be Found

  Following are solutions to try when OS/2 2.0 displays a message that it
  cannot find the COUNTRY.SYS file:

  o   If you have a PS/2(*) P70, contact your IBM customer engineer or computer
      dealer and request the engineering change announcement "ECA068".

  o   Find out if a diskette drive or a hard disk drive controller has an
      additional device attached to it, such as a tape backup.  Disconnect the
      device, if possible.

  o   Make sure the diskette drive or hard disk drive controller resides at its
      own IRQ level.  Refer to the operations manual that came with your
      computer for information about the IRQ setting.

      Refer to Chapter 9, "Hardware Support," for more information about
      setting IRQ levels.


  SYS1200 and EC=00BF

  If you see the error message "SYS1200" while attempting to use the Dual Boot
  feature to change to DOS, and you also see error code "EC=00BF" (meaning that
  the DOS environment cannot be created), check your CONFIG.SYS file.  Make
  sure your virtual DOS device drivers are listed correctly in your CONFIG.SYS
  file.


  COMPUTER BEEPS CONSTANTLY

  If your computer beeps constantly while you are changing diskettes during
  installation, you might have a defective-diskette drive controller or cable.
  Check the controller and cable for damage, and also check all their
  connections.


  WHITE SCREEN PROBLEMS

  The following sections provide problem determinations if you encounter a
  white screen during or after installation.

  With Disk Light On Constantly

  If you are installing OS/2 2.0 on a fast 486 ISA-bus computer, you might see
  a white screen and the disk light constantly on.  If so, try switching the
  system board out of turbo mode, to reduce the speed of the computer.  Refer
  to the documentation that came with your computer to find out how to change
  the mode.


  After Installation

  If the display screen is white after installation and there is no system
  activity, set the video adapter to 8 bits and move the adapter to an 8-bit
  slot.  If possible, disable the auto-switching capability of the video
  adapter.  Refer to the documentation that came with your video adapter.


  With an ATI Video Adapter

  If the display screen is white after installation, and you have an ATI
  8514/ULTRA or Graphics Ultra video adapter, you might have an early version
  of a video ROM chip on the adapter. Contact ATI at 416-756-0711 to request an
  update.


  BIOS PROBLEMS

  Following is information about systems and system boards that do not support
  OS/2 2.0 because of an earlier version of the BIOS.  Information is provided
  about how to upgrade the BIOS.


  Phoenix BIOS

  You must have a level 1.02.05D, or later, BIOS from Phoenix to run OS/2 2.0.


  AMI BIOS

  The later BIOS versions from American Megatrends, Inc. (AMI) provide a screen
  ID code, which is visible at the lower-left corner of the screen during the
  initial random-access-memory (RAM) count.  The code can be made to reappear
  if you restart the system by pressing Ctrl+Alt+Del, or it can be frozen
  on-screen by holding down the Ins key during system startup.  This creates a
  keyboard error, which will stop the screen for the error message:

    AMI BIOS and AMI BIOS Plus:   aaaa-bbbb-mmddyy-Kc

    AMI Hi-Flex BIOS:   ee-ffff-bbbbbb-gggggggg-mmddyy-hhhhhhhh-c

  If the screen ID code is in a form other than the above, the BIOS is either
  (1) a very early version, or (2) it was produced by a company with
  source-code license.  In the first case, contact Washburn & Co. at
  716-248-3627.  In the second case only, the system board manufacturer will be


  2-10  Tips and Techniques









  able to provide further information or updates.  All Everex** 368 BIOS
  versions are in the second category.

  GENERAL RULES:

  1.  If an IDE-type hard drive is installed, the date mmddyy should be 040990
                                                       ______
      or later for use with any operating system, including DOS.  This is
      because of the special timing requirements of IDE drives, which were
      accommodated on the date noted.
  2.  With any other drive type, such as MFM, RLL, ESDI, or SCSI, the OS/2
      operating system might install and operate correctly if mmddyy is 092588
                                                              ______
      or later, provided that the Keyboard Controller revision level is
      suitable for the OS/2 version being used.  Also, in the case of SCSI hard
      drives, a driver compatible with the version of OS/2 operating system
      being installed might be provided by the controller manufacturer, and if
      so, a special installation procedure might apply.
  3.  The Keyboard Controller revision levels ("c" in the previous screen ID
      code examples) expected to produce proper installation and operation of
      the various OS/2 operating system versions are as follows:

        OS/2 1.0 or 1.1:  8, B, D, or F
        OS/2 1.2x:  D or F
        OS/2 1.3x or 2.0: F

  4.  If the Keyboard Controller revision level shows as 0 or M, the Keyboard
      Controller chip is not an AMI chip, even if an AMI license sticker was
                         ___
      applied to it by the system board of original equipment manufacturer
      (OEM).  This means that its performance under the OS/2 operating system
      is unknown.  It might or might not work correctly.  In some cases,
      (usually "M"), an AMI chip can successfully replace a non-AMI chip, but
      this is not a general rule.  Sometimes the nonstandard Keyboard
      Controller (usually "0") was used to combine system board functions not
      normally part of the controller.  Substituting a standard chip causes the
      board to not function at all.  In this case, there is no solution other
      than to replace the board.  A revision level of 9 accompanied by a
      nonstandard ID code, also indicates a nonstandard controller (and BIOS).
      The system board manufacturer should be contacted for further
      information.

  BIOS UPDATES:  If a BIOS prior to the previously noted dates requires
  replacement, note the following:

  1.  AMI BIOS and BIOS Plus series BIOS (16 character ID code) for cached
      system boards are customized for individual system board designs.  They
      can only be obtained from the system board OEM, with only three common
      exceptions:
      a.  BIOS's with "aaaa" = E307 can often be replaced with a standard type.
      b.  BIOS's for Northgate or Motherboard Factory system boards, except the
          Northgate Slimline, can be replaced by a standard type.  Slimline
          BIOS's have the VGA BIOS in the same chips. They can be updated to
          the 040990 release, provided they are identified as Slimline, and the
          speed is specified (20,  25, or 33 MHz).  The speed must be specified
          because different VGA code is required for the various speeds.



                                  Chapter 2.  Installation Considerations  2-11









      c.  BIOS's with "aaaa" = DAMI, DAMX, or EDAMI are usually for cached
          boards designed or built by AMI, and if so, can be updated.  Mylex or
          Leading Technology boards with these prefixes can only be updated by
          the board manufacturer.
  2.  The complete screen ID code is necessary to determine whether a BIOS
      update for other system boards can be provided.  In the case of the
      Hi-Flex BIOS, the complete second and third lines of the ID code are also
      necessary.  If not immediately visible on the screen, they can be viewed
      by pressing the Ins key during system startup.
  3.  If you have a hard disk drive from another manufacturer, it must be dated
      092588 or later.

  If your hard disk drive is an early version, contact the dealer at your place
  of purchase, or the manufacturer, for information about upgrading the drive.


  Micronics System Board

  If your computer does not work properly, (for example, you receive a "divide
  underflow" message), you might have revision E of a Micronics system board.
  This board contains an early version of BIOS.  If you purchased the board
  from Gateway, contact Gateway 2000, Inc. at 800-523-2000 and request an
  upgrade to revision F.


  Gateway 2000 Computer

  If you have an early version of a Gateway 2000 computer that does not work
  properly, your BIOS might be an early version.  The company suggests that you
  replace the system board.  Contact Gateway 2000, Inc. at 800-523-2000 for
  information about upgrading your computer.


  Gateway 486 Computers

  If you have a Gateway 486 computer with a Rev E system board, there is
  potential for a DIVIDE UNDERFLOW error.  The error is caused when running
  software that takes advantage of the 486 math coprocessor.  If this error
  occurs, you can upgrade to a Rev F system board by contacting Gateway.


  Gateway Computers and Trap 2 Errors on Boot or Installation

  Gateway computers that cause a Trap 2 error are caused by one of the
  following:

  o   A bad Read Ahead Cache on the system board
  o   Bad memory

  When the problem is a bad Read Ahead Cache on the system board, press
  Ctrl+Alt+Esc to disable the external caching.  Contact Gateway when this
  problem is encountered.




  2-12  Tips and Techniques









  When the problem is bad memory, try moving the memory sims.  If the problem
  is not corrected, locate the memory sim that is bad and replace it.


  Gateway Nomad Notebook

  If you receive a "COUNTRY.SYS not found" message, your computer needs a BIOS
  upgrade.

  NOTE:  If a trap error appears when the system is started, or during
         installation, disable caching on the system board.  If the problem
         persists, contact Gateway 2000, Inc. at 800-523-2000.


  ZEOS NOTEBOOK

  If you have a ZEOS notebook and the installation of OS/2 2.0 fails, you can
  correct the installation problem by adding a patch to your Installation

                     __________
  the installation at Diskette 9 after doing the following:
                      __________

  1.  Identify which diskette was being "unpacked" when the installation
      procedure stopped.

  2.  Subtract the number of that diskette from 15 and add one to the result if
      you have 3.5-inch installation diskettes.  (Subtract the number from 18
      if you have 5.25-inch installation diskettes.)  For example, if you were
      on Diskette 9 on a 3.5-inch system, the result would be 7.
         __________                                           _

  3.  Start the computer with the Installation Diskette, and then insert

  USING DOS AND WINDOWS APPLICATIONS
  __________________________________

  Following is information about running DOS or Windows applications:

  NEWLY INSTALLED DOS OR WINDOWS APPLICATIONS:  After installation, and before
  you run any DOS or Windows applications, shut down your system and restart
  it.  You only have to do this once, immediately after you finish installing
  OS/2 2.0.

  EXISTING APPLICATION NOT MIGRATED:  Occasionally, the Migrate Applications
  program might not find all applications.  In this case, retry the Find
  Programs operation.

  WINDOWS VERSION 3.1:  IBM's testing of Windows Version 3.1 indicates that the
  OS/2 2.0 Installation program will not configure your WIN-OS/2* desktop.  If
  the Windows directory that is found is from a Windows Version 3.1
  environment, either change the DOS PATH to point to a Windows Version 3.0
  environment, or select the default environment.

  so, end the programs before you switch to DOS.


  USING BOOT MANAGER
  __________________

  Following is information about using the Boot Manager.





  2-16  Tips and Techniques









  BOOT MANAGER MENU BYPASS

  The Setboot utility program supports an immediate-restart function that will
  restart the system to the specified drive without going through the Boot
  Manager Menu.  The parameter is /IBD:DRIVE, where DRIVE is the letter of a
                                       _____        _____
  startable partition.  For example, from the OS/2 command prompt, you can type

       SETBOOT /IBD:E

  to start the logical drive E without displaying the Boot Manager Menu.  (If
  the Boot Manager is not present, then only drive C can be specified.)


  OS/2 VERSION 1.3 IN A PARTITION WITH DUAL BOOT

  If you are using Boot Manager, and one of your partitions contains OS/2
  Version 1.3 with Dual Boot, copy BOOT.COM from the OS/2 2.0 \OS2 subdirectory
  to the OS/2 Version 1.3 \OS2 subdirectory.


  USING NON-IBM COMPUTER WITH TWO DRIVES
  ______________________________________

  If you have a non-IBM computer with two hard disk drives, the second drive
  might not work properly after you install OS/2 2.0.  If so, reformat that
  drive with DOS or OS/2 2.0.

  CHAPTER 3.  SYSTEM PERFORMANCE CONSIDERATIONS
  _____________________________________________





  Following are some performance considerations that you should be aware of.
  For more performance guidelines, see the Information and Planning Guide

  document (G326-0160) that can be obtained from your place of purchase or
  retrieved through CompuServe.


  MEMORY REQUIREMENTS
  ___________________

  The minimum memory requirement for OS/2 2.0 is 4MB.  (This includes up to
  128KB that is used on some systems for ROM to RAM remapping.)

  Some systems use more than 128KB for other purposes, so less than the minimum
  required memory is available.  On these systems, you might need another 512KB
  to 1MB to satisfy the minimum requirements.  Check your system to see if it
  offers a way to recapture the memory so that you can regain the minimum
  requirement.

  Users concerned with response times when using some system functions, such as
  loading programs, starting sessions, and switching between sessions, can
  improve performance by increasing system memory.  If you are running on a
  constrained system (small hard disk, 16-MHz or less processor, 4MB of
  memory), an additional 2MB of memory will improve performance.  In the entry
  memory system (4MB), the recommended file system is the FAT file system.


  SWAPPER FILE
  ____________

  The system automatically preallocates the SWAPPER.DAT file based on the size
  of installed memory.  This is done to optimize performance and reduce disk
  fragmentation.  To tune the size of the swapper file, see the information
  about SWAPPATH in the Command Reference.
                        _________________

  In OS/2 2.0, the SWAPPER.DAT file is designed to shrink in size when the data
  segments are no longer needed, but does not shrink as expected.  This problem
  has been fixed by IBM APAR PJ03686, available from CompuServe or the IBM BBS.

  Ignore any CHKDSK errors that might be reported on the SWAPPER.DAT file.
  These error indications are normal.


  FILE SYSTEMS
  ____________

  Many performance changes have been incorporated into OS/2 2.0 file systems.
  They are the file allocation table (FAT) and the high performance file system
  (HPFS).  Both file systems read ahead (for sequential I/O), lazy write to
  disk, and accept threshold parameters.

  A disk cache size is preselected by the system based on installed memory,

  disk size, and file systems installed. The default for the entry memory
  system (4MB) is a cache size of 128KB.  To tune the size of the disk cache,
  see the information about DISKCACHE in the Command Reference.
                                             _________________


  DOS APPLICATION PROGRAMS
  ________________________

  You can improve the performance of some DOS application programs by adjusting
  the DOS settings.  If the program does not require extended or expanded
  memory, these values can be set to zero.  This will provide maximum
  performance.

  Some DOS programs use polling techniques to poll the system for work.  An
  example is a program that appears to be idle at an input prompt, but is in
  fact polling the keyboard looking for keystrokes.  Use the IDLE SENSITIVITY
  choice to detect this occurrence and suspend the program while it is polling.


  WINDOWS APPLICATION PROGRAMS
  ____________________________

  Windows application programs are generally started in one WIN-OS/2 session,
  unless specifically set to run in their own WIN-OS/2 session.  If you use
  several programs simultaneously, you might want to increase the DPMI memory
  limit before starting the first program.  The first program that is started
  determines the DPMI memory available for all subsequent Windows programs that
  are used.

  In low-memory configurations, you can run multiple Windows programs in one
  WIN-OS/2 session.  This reduces both memory and swapper-file requirements.

  With a WIN-OS/2 window session, a new session is created every time you
  double-click on an active object.  To restore the currently active object:

  o   Double-click on the minimized program object, or
  o   Display the OS/2 Window List and double-click on the program name.

  If you choose to migrate your Windows programs (at installation time or later
  using MIGRATE), most Windows programs will run in one WIN-OS/2 session.  If
  you set up a Windows program and do not use MIGRATE, each program runs in its
  own WIN-OS/2 session.

  If you are running Windows programs in a single WIN-OS/2 session, the Windows
  clipboard can be changed from Public to Private for increased performance.
  Setting it to Private means that it can be used in the single Windows
  environment only.

  When a large volume of data is being sent to the clipboard in a WIN-OS/2
  Window session, you might receive the message:

      Data not saved, possible memory or disk space error.
       This data not available in clipboard.

  followed by the message:



  3-2  Tips and Techniques









      Do you want to exit clipboard?

  Selecting OK to the second message will make the clipboard private to that
  WIN-OS/2 session.  Data that was previously sent to the Public clipboard
  might have remained private.  You might want to use the Private clipboard for
  programs receiving these messages.

  When you exit from a WIN-OS/2 session, the system leaves the clipboard and
  DDE loaded.  If you will not be returning to a WIN-OS/2 session, close both
  the clipboard and DDE.  Use the PM Window List to see if they are active.

  To permanently disable public DDE and clipboard exchange between Windows
  programs and Presentation Manager programs, and between Windows programs in
  separate WIN-OS/2 sessions, edit the OS2\MDOS\WINOS2\SYSTEM.INI file.  Under
  the "boot" section you will find the names of these two programs in the
  SAVDMApps= line, the MAVDMApps= line, and the WOS2VDMApps= line.  By removing
  the names of the programs from these lines, the programs will not be
  automatically started.  Adding them back will cause them to be started the
  next time a WIN-OS/2 session starts up.


  APPLICATION PROGRAM USAGE
  _________________________

  If you have an application program that you always use, you can set up the
  program in the Startup folder to load when the system is started.

  To avoid reloading frequently used programs, minimize the program after use
  and simply maximize it to use it again. You can find the program in the
  Window List or the Minimized Window Viewer.

  If you use several different programs, the icons (objects) can be placed on
  the desktop or in a folder.  The folder can be set to open when the system is
  restarted.

   TIP:  Close opened programs when you are not going to use them again.

         Close folders that you do not need.  Also, move commonly used
         functions out of folders and onto your desktop, and close the folders
         that contained the icons.


  HARD DISK SPACE
  _______________

  To save hard disk space, be certain to install only the functions you need.
  If you have installed the productivity aids and the games, and later only
  want a subset of these, delete all OS2\APP and OS2\APP\DLL files and use
  INSTALL to selectively install the items you want.  Additionally, delete
  TUTORIAL.HLP in OS2\HELP\TUTORIAL if you no longer need the tutorial.

  CHAPTER 4.  OS/2 WORKPLACE SHELL
  ________________________________





  This chapter describes tasks associated with using the OS/2 Workplace
  Shell(*).  For WIN-OS/2-specific topics, refer to Chapter 6, "WIN-OS/2
  Application Programs."


  STARTING UP YOUR SYSTEM
  _______________________

  This section describes information that controls the operation of your system
  at startup time.


  FILE SYSTEMS

  If you are using the file allocation table (FAT) file system, update your
  CONFIG.SYS file with the following statement to autocheck drive C (or your
  startable partition) to ensure disk data is verified prior to using the hard
  disk:

    DISKCACHE=64,LW AC:C

  If you are using the High Performance File System (HPFS), this function is
  done automatically.


  THE STARTUP FOLDER

  The Startup folder is the OS/2 Workplace Shell equivalent of the STARTUP.CMD
  file.  Objects placed in a Startup folder are started when the Desktop folder
  is opened.  You cannot specify the order in which the objects are started.

  NOTE:  Place program objects in this folder instead of the executable
         program-file objects.

  PREVENTING AUTOMATIC STARTUP

  If you want to prevent programs from automatically starting when the computer
  is restarted (for example, programs located in the Startup folder or programs
  that were running at the time the computer was shut down), do the following:

  1.  Press Ctrl+Alt+Del to restart the computer.
  2.  When the mouse pointer appears, press Ctrl+Shift+F1.
  3.  Hold the keys for approximately 15 seconds, or until the desktop icons
      appear.  (If the hard disk light stops during this time, your computer
      might be suspended.  Release the keys quickly, and then resume holding
      the keys until the desktop icons appear.)


  STARTUP.CMD FILE

  The STARTUP.CMD file is started before the OS/2 Workplace Shell is started;
  therefore, you cannot start applications using this file if they require an
  initialized shell.


  CUSTOMIZED STARTUP

  If you want a customized system startup, you can update your CONFIG.SYS file
  with the following statements:

  SET RESTARTOBJECTS =

  YES                       Default.  Start all objects that were running at
                            time of shutdown.

  NO                        Do not start any applications that were running at
                            time of shutdown.

  STARTUPFOLDERSONLY        Start objects only in the Startup folder.

  REBOOTONLY                Start objects only if the OS/2 Workplace Shell is
                            starting after resetting with Ctrl+Alt+Del or
                            turning on the computer.  This parameter can be
                            used with one of the other parameters (for example,
                            YES).















  4-2  Tips and Techniques









  SET AUTOSTART =

  FOLDERS                   Folders are opened, including the Desktop folder.

  TASKLIST                  The Window List is opened.

  PROGRAMS                  Programs are opened.

  CONNECTIONS               Re-creates the network connections established when
                            you last logged on.

  NOTE:  The SET AUTOSTART statement is used to start parts of the OS/2
         Workplace Shell.  Eliminating any of the options in the list restricts
         users from accessing portions of the shell (for example, limiting a
         user to only a few applications).


  USING ICONS
  ___________

  The following sections describe some of the tasks associated with using
  Icons.  Icons are miniature pictures that represent an object.  For example,
  ______
  if you install a printer, your printer object appears as a miniature picture
  of a printer.


  REDRAWING ICONS, TABS, OR BIT MAPS

  o   Because of system (memory) resource limitations, when too many
      applications are open, or when too many bit maps are visible on the
      screen, new icons, tabs, or other bit maps might not be drawn.  To remedy
      this, close unused folders and applications so the resources can be used
      by other processes.

  o   If some system icons (such as OS/2 System or Shredder) do not appear when
      you start the operating system, you can reset the desktop to its default
      configuration by doing the following:

      WARNING:  THIS PROCEDURE REMOVES ANY DESKTOP CUSTOMIZATION DONE SINCE
      INSTALLING THE OPERATING SYSTEM.

      1.  Press Ctrl+Alt+Del to restart the computer.
      2.  Before the OS/2 Logo panel appears, hold down Alt+F1 for 20 seconds.

      The current versions of the CONFIG.SYS, OS2.INI, and OS2SYS.INI files are
      renamed and replaced by the default installation versions in the
      \OS2\INSTALL subdirectory.  If you have a STARTUP.CMD file, it also is
      renamed.  This deactivates the startup feature.









                                          Chapter 4.  OS/2 Workplace Shell  4-3









  CHANGING ICON POSITIONS

  If you install IBM LAN Server 2.0, the positions of the icons on your screen
  might change.  To rearrange the icons:

  1.  Display the pop-up menu for the Desktop folder by clicking mouse button 2
      on an area not covered by any objects or windows.

  2.  Click on Arrange.


  CHANGING THE COLOR OF ICON TITLE TEXT

  If you want to change the color of the title text of all the icons in a
                                                       ___
  folder, do the following:

  1.  Select OS/2 SYSTEM.
  2.  Select SYSTEM SETUP.
  3.  Select COLOR PALETTE.
  4.  Press and hold Ctrl; then, pressing and holding mouse button 2, drag a
      color to an icon.  Drop the color; then release Ctrl.

  NOTE:  You cannot change the color of individual icon-title text.


  RECOVERING ICONS

  o   If you lose a folder by moving it to a folder you are unable to access,
      you can recover the folder.  From an OS/2 Window, use the MOVE command to
      relocate the folder (for example, the OS/2 System folder, "OS!2_SYS"), to
      the proper location.

      WARNING:  THE FOLLOWING PROCEDURE SHOULD BE USED ONLY IF A FOLDER IS
      INACCESSIBLE TO THE OS/2 WORKPLACE SHELL.

      To move a folder (for example, the "OS!2_SYS" folder):

      1.  Change to the directory where the "OS!2_SYS" folder is located.
      2.  Type the following to move the folder back to the Desktop folder.
          For FAT, type:


                MOVE OS!2_SYS \OS!2_2.0_D

          For HPFS, type:

                MOVE "OS!2 SYSTEM" \"OS!2 2.0 DESKTOP"



  o   If, intermittently, the icons on your desktop open normally but appear
      black, there might have been a timing problem that occurred when a new
      icon was saved using the General page in the settings notebook.  Try
      correcting the appearance by re-creating or restoring the icon.


  4-4  Tips and Techniques









  CREATING AN ICON FOR AN APPLICATION

  If you want to create an icon for a DOS, Windows, or OS/2 application that
  does not have one, but has graphics within the application, do the following:

  1.  Run the application in a window session.
  2.  When you see an icon-sized graphic that you would like to use as the icon
      to represent your program, size the window, making the image
      approximately the size of a desktop icon.
  3.  Click on the title-bar icon (in the upper-left corner of the window);
      Select MARK.
  4.  Mark the graphic.
  5.  Select COPY to move the graphic to the clipboard.
  6.  Display the pop-up menu for the object by moving the mouse pointer to it
      and clicking mouse button 2.
  7.  Click on the arrow to the right of OPEN.
  8.  Select SETTINGS; then select the GENERAL tab to display the default icon.
  9.  Select CREATE ANOTHER to display the Icon Editor.
  10. Select FILE, NEW, ICON; then select OK.
  11. Select EDIT, then PASTE to paste in your graphic.  If necessary, use the
      Icon Editor to make any changes you want in the graphic.
  12. Select FILE, then SAVE to store the program name.ICO file in the same
                                          ____________
      drive and directory as the program file (.COM or .EXE file).
  13. Double-click on the title-bar icon to exit the editor.
  14. From the settings notebook, Select FIND; then locate the saved .ICO file.
      (Selecting DRIVES is the easiest search.)
  15. Click on the icon; then save the file.
  16. Exit the settings notebook.  The original icon is replaced with the
      graphic from the application.


  RESTORING THE DESKTOP
  _____________________

  If your desktop becomes damaged (for example, you started a specific version
  of DOS and rearranged your hard disk, damaging .INI files or extended
  attributes), you must restore the initial .INI and CONFIG.SYS files to
  restore the desktop.  However, any modifications (such as shadows and
  associations created after installation) are lost and must be re-created.


  UPDATING THE .INI FILES

  To restore the desktop, do the following to update your existing .INI files:

  1.  Restart your computer using the OS/2 Installation Diskette; then insert
                                      __________________________
      Diskette 1.
      __________
  2.  Press Esc to access an OS/2 full screen; then change to the \OS2
      directory.
  3.  Type:

        MAKEINI OS2.INI INI.RC  (and press Enter)

        MAKEINI OS2SYS.INI INISYS.RC  (and press Enter)



                                          Chapter 4.  OS/2 Workplace Shell  4-5









  4.  Delete the hidden file WP ROOT. SF in the startable partition.  For HPFS,
      type:

        ATTRIB -h -s -r "WP ROOT. SF"  (and press Enter)

      For FAT, type:

        ATTRIB -h -s -r WP_ROOT._SF  (and press Enter)

      Next, for HPFS type:

        DEL "WP ROOT. SF" (and press Enter)

      For FAT, type:

        DEL WP_ROOT._SF (and press Enter)


  If the above procedure does not fix the problem, do the following to recover
  the backup .INI files.  You will lose all your desktop customization, but the
  desktop should be restored.

  1.  Press Ctrl+Alt+Del to restart your computer.
  2.  As soon as you hear a single beep, or you press Enter at the Boot Manager
      menu or power-on password prompt, press and hold Alt+F1.  Hold these keys
      down until you hear rapid beeping.


  RE-CREATING THE .INI FILES

  If the preceding procedures do not fix the damaged desktop, do the following
  to re-create the .INI files:

  1.  Restart your system using the OS/2 Installation Diskette; then insert
                                    __________________________
      Diskette 1.
      __________
  2.  Press Esc to access an OS/2 full screen; then change to the OS2
      directory.
  3.  Delete the current .INI files.  Type:

           DEL OS2.INI (and press Enter)

           DEL OS2SYS.INI (and press Enter)

  4.  Re-create both files using the MAKEINI command.  Type:


           MAKEINI OS2.INI INI.RC (and press Enter)

           MAKEINI OS2SYS.INI INISYS.RC (and press Enter)

  5.  Change to the desktop directory, OS!2_2.0_D (FAT) or "OS!2 2.0 DESKTOP"
      (HPFS).
  6.  Delete all subfolders (subdirectories) in this directory.
  7.  Change to the root directory.


  4-6  Tips and Techniques









  8.  Delete the hidden file WP ROOT. SF in the startable partition.  For HPFS,
      type:

        ATTRIB -h -s -r "WP ROOT. SF"  (and press Enter)

      For FAT, type:

        ATTRIB -h -s -r WP_ROOT._SF  (and press Enter)

      Next, for HPFS, type:

        DEL "WP ROOT. SF"  (and press Enter)

      For FAT, type:

        DEL WP_ROOT._SF (and press Enter)

  9.  Press Ctrl+Alt+Del.  The desktop is reinstalled to its initial
      installation setup.
  10. Shut down the system using the SHUT DOWN choice on the desktop pop-up
      menu.

  NOTE:  Use MAKEINI instead of the Alt+F1 key combination if you do not want
         to replace the CONFIG.SYS file and desktop.  The installation process
         places a copy of the original OS2.INI, OS2SYS.INI, and CONFIG.SYS
         files in the \OS2\INSTALL subdirectory.  These are the same .INI files
         created with MAKEINI.  They will rebuild the desktop and set it to its
         initial installed state.

         Alt+F1 replaces OS2.INI, OS2SYS.INI, and the CONFIG.SYS files.


  ADDING AN OS/2 WINDOW TO THE DESKTOP MENU
  _________________________________________

  If you want another method of accessing an OS/2 Window, you can add OS/2
  WINDOW as a new menu choice on the desktop pop-up menu.  Do the following:

  1.  Display the pop-up menu for the Desktop folder by clicking mouse button 2
      on an area not covered by any objects or windows.
  2.  Click on the arrow to the right of OPEN.
  3.  Select SETTINGS; then select the MENU tab.
  4.  From the ACTIONS ON MENU choices, select CREATE ANOTHER.
  5.  In the MENU ITEM NAME field, type:

           OS/2 Window

  6.  In the PROGRAM NAME field, type:

           C:\OS2\CMD.EXE

      Change to a different drive, if necessary.
  7.  Select OK.
  8.  Double-click on the title-bar icon to close the notebook.



                                          Chapter 4.  OS/2 Workplace Shell  4-7









  9.  Display the Desktop folder pop-up menu again.  "OS/2 Window" is added to
      the available menu choices.  If you select this choice, an OS/2 Window is
      displayed.


  USING EXECUTABLE FILES
  ______________________

  Do not move program-file objects (.EXE, .COM, .CMD, and .BAT files) from
  their installed directories (for example, moving a program-file object from
  the Drives folder to a new location).  Moving program-file objects might
  cause some program objects to not function properly.  Instead, create a new
  object that refers to the original, either a program object or a shadow; then
  you can move the new object to a location of your choice.  (Program-object
  settings and shadow settings specify the location of the original
  program-file object.)  To create a program object or shadow:

  1.  Display the pop-up menu for the program-file object by moving the mouse
      pointer to it and clicking mouse button 2.
  2.  Select CREATE ANOTHER or CREATE SHADOW.
  3.  Select a folder for the new object; then select CREATE.

  NOTE:  The CREATE ANOTHER choice, when used on a program-file object, creates
         a program object, not a program-file object.


  CHANGING A DEFAULT FOLDER VIEW
  ______________________________

  If you want to change the default view for displaying the objects within a
  folder (for example, icon versus details view), do the following:

  1.  Display the pop-up menu for the folder by moving the mouse pointer to it
      and clicking mouse button 2.
  2.  Click on the arrow to the right of OPEN.
  3.  Select SETTINGS; then select the MENU tab.
  4.  Select OPEN in the AVAILABLE MENUS field.  The Menu Settings window is
      displayed.
  5.  In the DEFAULT ACTION field, select the default you want.
  6.  Select OK.


  USING THE MINIMIZED WINDOW VIEWER
  _________________________________

  o   In the Minimized Window Viewer settings notebook, disregard "Page 1 of
      3."  Each section of the notebook contains 1 page only.

  o   Some objects, such as WIN-OS/2 programs, online books, and programs that
      start other programs, do not minimize to the Minimized Window Viewer.









  4-8  Tips and Techniques









  USING FIND
  __________

  o   In the Help information for Find, disregard any references to "page 2."
      Page 2 does not exist in Find operations.

  o   If you change the title of an object from within the Find Results folder,
      the name of the original object is changed.


  AVOIDING AN "INCORRECT DOS VERSION" MESSAGE
  ___________________________________________

  If you receive the message "Incorrect DOS version" when trying to run a DOS
  application under OS/2 2.0, the application is using an earlier version of
  DOS on your computer.  To fix the problem, update the DOS setting DOS_VERSION
  using the Value field of the DOS Settings window.  For example,

               PROG.EXE,5,0,255

    (program, major version, minor version, count)

  This setting simulates the DOS 5.0 version check as opposed to the OS/2 2.0
  version check.


  USING ANSI COLORS AND CHARACTERS IN DOS SESSIONS
  ________________________________________________

  If you want to use ANSI colors and characters in your DOS sessions, do the
  following:

  1.  Add the following statement to your CONFIG.SYS file:

        DEVICE=C:\OS2\MDOS\ANSI.SYS

  2.  Shut down your computer.
  3.  Press Ctrl+Alt+Del to restart your computer and make the change active.


  USING THE HIGH PERFORMANCE FILE SYSTEM
  ______________________________________

  o   If you formatted your installed drive with the High Performance File
      System (HPFS), you might not be able to access files in the Desktop
      folder from DOS or WIN-OS/2 applications.  DOS and WIN-OS/2 applications
      use the FAT file system.  If you experience this problem, the partition
      should be reformatted with the file allocation table (FAT) file system.

  o   If you are typing a command in the HPFS, you must include double
      quotation marks around the name of the subdirectory or file name if it
      contains blanks.  For example, to change to the OS!2 2.0 DESKTOP
      directory, type:

        CD "OS!2 2.0 DESKTOP"

      As another example, to copy the file This is my file from the root
                                           _______________
      directory to the This is my directory subdirectory, type:
                       ____________________


                                          Chapter 4.  OS/2 Workplace Shell  4-9









        COPY "THIS IS MY FILE" \"THIS IS MY DIRECTORY"

  NOTE:  In the FAT file system, HPFS file names are shortened.  Underscores
         represent blank spaces.


  SHUTTING DOWN
  _____________

  o   Sometimes when system (memory) resources are limited, the final shutdown
      message might not appear after a shutdown is performed.  To ensure that
      shutdown is complete, wait until all disk activity stops before turning
      off or restarting your computer by pressing Ctrl+Alt+Del.

  o   If you want to shut down your system without using a mouse, do the
      following:

      1.  Press Ctrl+Esc to display the Window List.
      2.  Press the Up Arrow (A) to move the cursor to "OS/2 2.0 Desktop - Icon
          View"; then press Enter.
      3.  Press Ctrl+\ to deselect any selected icons.
      4.  Press Shift+F10 to display the pop-up menu for the desktop.
      5.  Press the Down Arrow (V) to move the cursor to SHUT DOWN; then press
          Enter.

  o   You should shut down your system before restarting or turning off your
      computer; however, there are situations where you might want to restart
      your system by pressing Ctrl+Alt+Del instead:

      -   If you used the ARRANGE choice on the Desktop folder pop-up menu, it
          rearranged the icons you placed in specific positions on the screen.
          Restarting your system recovers your icon positions.

      -   If you opened several folders containing many icons, shutdown will
          take a long time saving the positions of the icons.  You might want
          to restart your system without using the SHUT DOWN choice on the
          desktop pop-up menu as long as you are certain that you will not lose
          anything else of importance.

  o   If you shut down your system, but do not receive the message "Shutdown
      has completed.  It is now safe to turn off your computer...", you should
      wait for all disk activity to stop, and then you can turn off your
      computer or press Ctrl+Alt+Del.

  CHAPTER 5.  APPLICATION PROGRAMS
  ________________________________





  Most DOS, Windows, and OS/2 programs run under OS/2 2.0 without any
  modification.  A few need specific attention.  This chapter provides that
  information.


  INCOMPATIBLE PROGRAMS
  _____________________

  The following identifies categories of programs that do not work correctly
  with OS/2 2.0.

  o   DOS extenders that require exclusive access to the 80386 control
      registers, such as the Virtual Control Program Interface (VCPI), are not
      supported because they would conflict with OS/2 2.0 operations.  The DOS
      Protect-Mode Interface (DPMI 0.9), the Expanded Memory Specification
      (EMS), and the Extended Memory Specification (XMS) are supported.

  o   Programs that directly address the physical disk sectors to perform
      disk-write operations are not supported.  These operations would conflict
      with OS/2 2.0 operations.  This category includes most DOS UNDELETE
      programs.

  o   Some Windows programs make use of the Windows accessory programs, like
      the Calculator.  If you already had Windows Version 3.0 installed and you
      did not format your hard disk when you installed OS/2 2.0, the accessory
      programs are on your hard disk and are supported by OS/2 2.0.  However,
      the accessory programs are not part of the WIN-OS/2 environment included
      with OS/2 2.0.

  o   Programs (and hardware) that require the Windows Enhanced mode are not
      supported.  This mode uses an unsupported memory-management method.
      Programs that run in Windows standard mode and real mode are supported.

  o   Programs that manipulate the 80386 control registers, such as 386 DOS
      debuggers, are not supported; this would conflict with OS/2 2.0
      operations.

  o   Fax boards and programs that use more that 1000 interrupts per second
      (9600 baud or greater) are not supported.  The following fax boards and
      programs contain timing sensitivities that might prevent reliable
      operation:

      -   ATI ETC
      -   Cardinal FAX
      -   Practical Peripherals
      -   Smartfax**
      -   Twincomm 24/96




  (C) Copyright IBM Corp. 1992                                              5-1









      The programs listed here fit into one or more of the categories listed in
      the previous section:

      -   Ansel for Windows
      -   Bound Checker (DOS)
      -   Central Point Backup** for Windows
      -   Close-Up (Windows)
      -   Desert Storm CD-ROM (Windows)
      -   Distinct** Back-Up (Windows)
      -   DoDot 3.0 (Windows)
      -   Fax Concentrator (DOS)
      -   Magic-CV (DOS)
      -   Mathematica 2.0 (Windows)
      -   MusicPrinter Plus** 4.0 (DOS)
      -   Omnipage Professional** 1.0 (Windows)
      -   Oracle (DOS)
          (There is an OS/2 version of this program.)
      -   Perceive for Windows
      -   PharLap** DOS extenders prior to Version 4.0
      -   Realizer** 1.0 (Windows)
      -   Sherlock Holmes CD-ROM (DOS)
      -   Smartfax (DOS)
      -   Soft-ICE (DOS)
      -   Splash 1.01 (DOS)
      -   Turbo Debugger (DOS)


  IMPROVING PROGRAM COMPATIBILITY
  _______________________________

  The following provides techniques that improve program compatibility:

  o   For more reliable DOS communications performance on slower systems, the
      combined baud rate should not exceed 9600 bps for one or more concurrent
      DOS applications.

  o   You can improve the performance of DOS communications programs by using
      the 16450 UART or 16550AFN UART communications chips.

  o   If you run a bulletin board or a DOS communications application that
      keeps timing out, change the DOS settings as indicated below.  If the
      first settings change does not fix the problem, change the next settings,
      and so forth.

      1.  HW_TIMER to ON
      2.  IDLE_SECONDS to 60, and IDLE_SENSITIVITY to 100
      3.  COM_HOLD to ON
      4.  HW_ROM_TO_RAM to ON
      5.  If you lose data using DOS communications software, set the
          PRIORITY_DISK_IO setting to NO in your CONFIG.SYS file, and the
          IDLE_SENSITIVITY setting to 100% in the DOS settings for the object.

      If the DOS-settings changes do not fix the problem, set PRIORITY_DISK_IO
      to NO in the CONFIG.SYS file.



  5-2  Tips and Techniques









  o   Some DOS and Windows programs run correctly only in full-screen sessions.
      Any Windows program that does not use the Windows application program
      interface (API) function to change the video mode should be run in a
      WIN-OS/2 full-screen session.

  o   Some DOS and Windows programs must be installed or run in a specific DOS
                                                                  ____________
      session.  A specific DOS session is started by booting from an actual
      _______
      version of DOS.  For more information, refer to "DOS, starting specific
      version" in the online Master Help Index.

  o   Some programs run in OS/2, DOS, or WIN-OS/2 sessions, but require that
      you install the program under DOS.

  o   Windows programs cannot start DOS sessions or DOS programs.

  o   DOS programs that use low-level file-system calls cannot access HPFS
      disks.

  o   If you are running communications programs, set the CONFIG.SYS statement
      PRIORITY_DISK_IO to NO; then restart your system.

  o   Code-page-switching support is not available for graphics mode in DOS
      sessions.

  o   Some DOS and Windows programs use security keys as protection against
      copyright infringement.  The security key is a 25-pin connector that is
      connected to the parallel port of the computer on which the program is
      executing.  The program checks to see if the connector is attached and,
      if the connector is not present, the program is assumed to be an illegal
      copy.  When more than one DOS session is running one of these programs, a
      SYS1799 error can result.  This occurs because the programs that use
      these security keys do not de-allocate the parallel port if a second
      session is started for a program that also requires the security key.
      This error is the result of a direct I/O parallel port contention
      mechanism that protects the user from possible data corruption.  To
      disable this mechanism:

      1.  Display the pop-up menu for the printer object by moving the mouse
          pointer to it and clicking mouse button 2.
      2.  Click on OPEN; then SETTINGS.
      3.  Click on the Output tab.
      4.  Double-click on the LPT port that has the contention problem.
      5.  Select Shared access to share the port between DOS sessions doing
          direct I/O to the parallel port.
      6.  Click on OK.

  o   Some Windows Multimedia Extension programs might not work correctly after
      being migrated to OS/2 2.0.  If this occurs, reinstall them under
      WIN-OS/2.

  o   If the SYS0005 error "ACCESS DENIED" occurs when starting DOS programs,
      follow this procedure:

      1.  Shut down the system.


                                          Chapter 5.  Application Programs  5-3









      2.  Insert the Installation Diskette into drive A.
                     _____________________

      3.  Restart the system.

      4.  When prompted, remove the Installation Diskette, insert Diskette 1,
                                    _____________________         __________
          and press Enter.

      5.  At the "Welcome to OS/2" screen, press Esc.

      6.  Remove Diskette 1 and insert Diskette 2.
                 __________            __________

      7.  At the command prompt, type "CHKDSK C: /F:3 " and press Enter.

      8.  If you receive the error "cross-linked extended attribute", repeat
          the previous command until CHKDSK reports no errors.

      9.  After repeated attempts, if CHKDSK continues to report errors, note
          the names of the files related to the errors.  Copy these files to a
          blank diskette and delete the files from the hard disk.  Then, run
          CHKDSK again.

      10. When CHKDSK reports no errors, copy the files back to their original
          location, and restart your system.

      NOTE:  This problem usually occurs when an EADATA file is deleted from
             DOS.  If you have DOS, copy files to another directory or name;
             delete the originals, and then copy back to the original location.


  SPECIFIC PROGRAM COMPATIBILITY
  ______________________________

  The following list provides information about the compatibility of specific
  programs with OS/2 2.0.  This information is version specific; later versions
  of the same program might operate correctly.  Some program manufacturers
  already have resolved incompatibility issues and have fixes available; these
  are noted.

      ACTION! SAMPLER 1.0 (WINDOWS)

      o   The DPMI_MEMORY_LIMIT WIN-OS/2 setting must be set to 5 or greater.

      ADOBE TYPE MANAGER (WINDOWS)

      o   When using an IBM 4029 printer in PPDS mode with Adobe** Type
          Manager**, some Windows programs might not function correctly.  If
          this occurs, do not use the printer's resident fonts.  To disable the
          printer's resident fonts, bring up the control panel of the Windows
          Adobe Type Manager and ensure that the selection "Use Pre-built or
          Resident Fonts" is disabled.

      AFTER DARK (WINDOWS)

      o   To run this program in a WIN-OS/2 window session, change the object's
          settings to Hide or minimize the program object to the desktop.


  5-4  Tips and Techniques









      o   This program places a TSR (terminate and stay-resident) reference in
          the AUTOEXEC.BAT file when it is installed.  To run in a WIN-OS/2
          window session, remove this reference from AUTOEXEC.BAT.





















































                                          Chapter 5.  Application Programs  5-5









      ALDUS PAGEMAKER 4.0 (WINDOWS)

      o   The spelling checker cannot locate the dictionary.
      o   Deselect the Public setting to use the clipboard.
      o   If you experience incorrect output when spooling Standard format
          files to the printer, set the printing to RAW mode.  To do this, take
          the following actions:
          1.  Go to the Printer icon on the desktop.
          2.  Select OPEN, then SETTINGS, then QUEUE OPTIONS.
          3.  Ensure that PRINTER SPECIFIC FORMAT is checked.

      ALDUS PERSUASION 2.0 (WINDOWS)

      o   Use the parallel ports to print.
      o   Deselect the Public setting to use the clipboard.

      ARTS & LETTERS GRAPHICS EDITOR 3.1 (WINDOWS)

      o   The DECIPHS utility program requires that a DOS session be started
          from the Windows environment; this is not supported.
      o   To run in a WIN-OS/2 window, change the object's settings to minimize
          to the desktop.
      o   The directory created by Arts & Letters is named A&L.  The ampersand
          character (&) is a reserved character of the command shell, CMD.EXE;
          it is used for conjugated command lines. To change to the A&L
          directory with the CD command, you must use one of two methods of
          quoting the directory name.  The first method is to prefix the & in
          A&L with a &caret. (caret, shift 6):

                 CD A&caret.&L

          The second method is to surround the entire directory name with
          quotation marks (" "):

                CD "A&L"

      o   If you are running Arts & Letters and you get a system error (a GDI
          trap), you must restart the operating system before running the
          program again.  This is because the program left a portion of itself
          running when it ended and will not start a new copy of itself while
          that portion is running.  This also means that when you restart the
          computer, Arts & Letters will start again automatically.  It is
          recommended that you close the copy that is opened on system startup
          and start the program from its icon when you intend to run it in a
          window.

      AUTOCAD VERSION 10 (DOS)

      o   Close the program from the desktop.  Use an HPFS partition as a
          workaround.  A fix is forthcoming from IBM.

      AUTOCAD (OS/2)




  5-6  Tips and Techniques









      o   Some of the background colors are set to a very pale color that does
          not show up well on XGA displays.

      AUTOMANAGER 4.0 (DOS)

      o   The version of the program that uses extended memory uses an
          unsupported DOS memory extender.  Use the real-mode version.
      o   The program expects COMMAND.COM to be in the root directory of drive
          C:\.  Copy COMMAND.COM from the C:\OS2\MDOS directory to C:\.

      BORLAND C++** 2.0 AND 3.0 (DOS)

      o   Set the DPMI_DOS_API DOS setting to Enabled.

      BORLAND TURBO C++ 2.0 (DOS)

      o   The version of the program that uses extended memory uses an
          unsupported DOS memory extender.  Use the standard-mode version of
          the program.

      BORLAND TURBO DEBUGGER 2.01 (DOS)

      o   The version of the program that uses extended memory uses an
          unsupported DOS memory extender.  Use the standard-mode version of
          the program.
      o   TD386, the 386 version of Turbo Debugger, manipulates the 80386
          control registers; this is not supported.

      BORLAND TURBO DEBUGGER FOR WINDOWS (WINDOWS)

      o   Run the program in a WIN-OS/2 full-screen session.
      o   The screen is temporarily corrupted when this program is called from
          Turbo C++.  The screen is restored on the first repaint.  (A repaint
          can be forced by clicking the mouse on several different windows.)

      BORLAND TURBO PASCAL 6.0 (DOS)

      o   The version of the program that uses extended memory uses an
          unsupported DOS memory extender.  Use the standard-mode version of
          the program.

      CENTRAL POINT BACKUP FOR DOS 7.1 (DOS)

      o   Displays meaningless characters when running in a DOS window session.
          Run this program only in a DOS full-screen session.

      CENTRAL POINT PC TOOLS DELUXE 7.1 (WINDOWS)

      o   Many of the utility programs require starting a DOS session from the
          Windows environment; this is not supported.  Start these programs
          from a separate DOS session.
      o   The backup feature of this program performs in a manner similar to
          Central Point Backup for Windows, which is in the list of programs
          that do not work correctly with OS/2 2.0.  If you experience


                                          Chapter 5.  Application Programs  5-7









          difficulty backing up on a diskette, back up on an alternate device,
          such as a network drive or a tape drive.

       TIP:  You might need to install this program under a specific DOS
             session.

      COMMANDER KEEN (DOS)

      o   Set the VIDEO_RETRACE_EMULATION DOS setting to OFF.

      COMMUTE (WINDOWS)

      o   When this program is installed under WIN-OS/2, the statement
          keyboard.drv=commkbd.drv is added to the SYSTEM.INI file.  Change
          this statement to keyboard.drv=keyboard.drv.

      CONTROL ROOM 1.0 (DOS)

      o   You must run this program in a DOS full-screen session for the screen
          blanking feature to work correctly.

      CORELDRAW 2.0 (OS/2)

      o   If you do a large amount of printing while in this program, it is
          possible that you might run out of system (memory) resources.  To
          avoid this, you should periodically save your work and exit
          CorelDRAW; then restart the program and continue your work.

      CORELDRAW 2.0 (WINDOWS)

      o   Install the program in a DOS session.
      o   Run the program in a WIN-OS/2 full-screen session.

      CORELDRAW 2.1 (WINDOWS)

      o    To install this program:
          -   Start a DOS session.
          -   Run FFIX /date (note that "date" must be lowercase).
          -   Type A: and press Enter.
          -   Exit WIN-OS/2.
          -   Run FFIX /u.
          -   Type INSTALL and press Enter.
      o   Run the program in a WIN-OS/2 full-screen session.

      CROSSTALK (WINDOWS)

      o   Type MODE COMx BUFFER=OFF at the command prompt, where x is the
                       _                                         _
          communications port you are using, before you run the program.

      DBASE IV 1.1 (DOS)

      o   If you receive a "too many files open" error message, set the
          DOS_FILES DOS setting to 30.  Set the DOS_VERSION DOS setting to



  5-8  Tips and Techniques









          DBASE.EXE,5,0,255.  With Hyperdisk, set DOS_VERSION to
          DBASE1.EXE,5,0,255.
      o   When using Hyperdisk, you might have to adjust the EMS and XMS memory
          limits.
      o   With the multi-user version, the program must be run in a specific
          DOS session.

      DESIGNER (OS/2)

      o   The MIRRORS.DLL that comes with this program must be installed in the
          program directory, not in the C:\OS2\DLL directory, and the program
          must be started from this directory.  This is because OS/2 2.0 comes
          with its own dynamic link library named MIRRORS.DLL.

      DRAFIX CAD VERSION 1.11 (WINDOWS)

      o   Run the program in a WIN-OS/2 full-screen session.

      DRAFIX CAD VERSION 3.0 (WINDOWS)

      o   Run the program in a WIN-OS/2 full-screen session.

      DYNACOMM** ASYNCHRONOUS OS/2 (OS/2)

      o   The DLL's included with this product must not be in the same
          directory as the executable file.  Put them in a separate directory
          and add that directory to the end of the LIBPATH.





























                                          Chapter 5.  Application Programs  5-9









      ENHANCED EDITOR (OS/2)

      o   The OS/2 Enhanced Editor supports up to 99 fonts.  If additional
          fonts are installed, unpredictable results might occur.
      o   In the online help for the Enhanced Editor, it states that you should
          contact your IBM representative for detailed information on how to
          program the editor.  Instead, obtain this information from the IBM
          bulletin boards.

      F-117A STEALTH FIGHTER 2.0 (DOS)

      o   Set the VIDEO_RETRACE_EMULATION DOS setting to OFF.
      o   If the program appears to stop at a blank screen soon after you start
          it, press Esc and the program will continue.  Once you are past the
          opening screens, the program runs correctly.

      F19 (DOS)

      o   Set the HW_ROM_TO_RAM DOS setting to ON and the
          VIDEO_RETRACE_EMULATION DOS setting to OFF.

      FASTBACK FOR WINDOWS (WINDOWS AND OS/2)

      o   Use only Version 1.01, a no-charge upgrade from Fifth Generation
          Systems.  To order, call 1-800-873-4384.
      o   In the Options pull-down menu in the program, make sure that the
          Media setting is set to the system default.  (The other Media
          settings write to DMA device drivers, which have incompatibility
          problems.)

      FASTBACK PLUS 2.1 AND 3.04 (DOS)

      o   If you experience difficulty backing up on a diskette, back up on an
          alternate device, such as a network drive or a tape drive.

      FASTLYNX 1.1 (DOS)

      o   To use the serial port with this program, remove the
          DEVICE=C:\OS2\MDOS\VCOM.SYS statement from CONFIG.SYS.  The parallel
          port works correctly.
      o   Due to its high speed, the program sometimes fails to function.  If
          this occurs, simply end the program; system integrity is not
          compromised.  To minimize the possibility of this error condition,
          set the following DOS settings:
          HW_TIMER = ON
          IDLE_SENSITIVITY = 100
          IDLE_SECONDS = 10

      FORM PUBLISHER (WINDOWS)

      o   Ensure that the program's printer driver is installed before running
          the program.

      FORMBASE 1.2 (WINDOWS)


  5-10  Tips and Techniques









      o   The SHARE statement is automatically added to AUTOEXEC.BAT during
          program installation.  Use an editor to remove the SHARE command from
          AUTOEXEC.BAT.
      o   When running this program and Lotus 1-2-3 in the same WIN-OS/2
          session, this program must be started first.

      INTEL SATISFAXTION (DOS)

      o   The program must be run in a specific DOS session.
      o   After installing Intel SatisFAXtion, you are told to remove the
          diskette and press any key to reboot your computer.  Instead, shut
          down the operating system and restart your computer.
      o   If SatisFAXtion software is loaded into each DOS session, it might
          cause the fax to stop if another DOS session is started.  Set up one
          DOS session to be used for faxing, and load the device driver and
          executable files only into that DOS session.  To do this, take the
          following steps:
          1.  Edit AUTOEXEC.BAT.
          2.  Cut the last two lines referring to the Intel SatisFAXtion board
              to the clipboard and save the file (using DOS Command File for
              the file type).
          3.  Open a New file.
          4.  Paste the last two lines into the new file.
          5.  Save the new file as FAX.BAT, using DOS Command File as the file
              type.


  5-12  Tips and Techniques









          6.  Edit CONFIG.SYS and cut the last two lines relating to the Intel
              SatisFAXtion board to the clipboard (cut only the last line if
              you do not have a scanner installed).
          7.  Save the file using Plain Text as the file type.
          8.  In the Command Prompts folder, select a DOS Full Screen icon,
              press the Ctrl key and mouse button 2 at the same time, move the
              mouse pointer to an empty area in the folder, and release the
              mouse button and the Ctrl key.  This creates a copy of DOS Full
              Screen.
          9.  Put the mouse pointer over your new icon and click on mouse
              button 2.
          10. Click on the arrow next to OPEN, and select SETTINGS.
          11. Go to the Session page and select the DOS SETTINGS push button.
          12. Go to DOS_DEVICE and click on mouse button 1.  Then, move the
              mouse to the dialog area and click on mouse button 1 (there
              should be a blinking cursor now).
          13. Paste the text that you cut from the CONFIG.SYS file and select
              SAVE.
          14. Go to the General page and replace the contents of the Title box
              with FAX (or whatever other title you choose).
          15. If you want to edit the new session's object, go to the General
              page and select the EDIT push button.
          16. If you want to have this session start each time your system
              starts, move the icon to the Startup folder.
          17. Whenever you start this session, type FAX to run the FAX.BAT file
              before using the SatisFAXtion board.  Use the fax board in only
              one session at a time.
      o   If you install the program using this procedure and you receive error
          messages, install the program under DOS.

      KING'S QUEST (DOS)

      o   Remove the DOS=HIGH statement, if one exists, from CONFIG.SYS or from

      LAN SUPPORT PROGRAM DEVICE DRIVERS (DOS)

      o   If you opened a DOS session with the DOS LAN Support Program (LSP)
          device drivers, and subsequently closed the session, you must ensure
          that the token-ring adapter is reset before using the LAN from
          another DOS session.  To ensure that the token-ring adapter is reset,
          use RESETOKN.EXE or RESETOKN.SYS.  These files can be retrieved from
          CompuServe by issuing GO IBMOS2 and downloading RESTKN.ZIP from
          SECTION 17, IBMFILES, or they can be retrieved from the IBM National
          Support Center Bulletin Board System by downloading RESTKN.ZIP.
      o   The IBM token-ring adapter should be used by only one session at a
          time.

      o   Do not use the program's shutdown function.

      SANTAFE MEDIA MANAGER (DOS)

      o   To install this program:
          -   Start a DOS session.
          -   Run FFIX /find (note that "find" must be lowercase).
          -   Install the program.
          -   Run FFIX /u.

      SIDEKICK (OS/2)

      o   A printer must be installed and present on the desktop to use the
          Notepad.

      SIGNMASTER 5.11 (DOS)

      o   The plot/preview feature causes an illegal instruction to be issued.

      SOFT TERM (OS/2)

      o   In the Send File and Receive File windows, the first time the drive
          is changed, the Directory window updates incompletely.  After the
          first time, the Directory window works normally.

      SOUNDBLASTER (DOS)

      o   The SBTEST utility program reports an incorrect DMA level during
          installation.  Disregard the error message and continue with
          installation.  The program will be installed correctly.
      o   The PARROT program does not run in a DOS session.

  CHAPTER 6.  WIN-OS/2 APPLICATION PROGRAMS
  _________________________________________





  This chapter contains information when running a Windows application program
  in a WIN-OS/2 session (window and full-screen).


  OPTIMIZING WIN-OS/2
  ___________________

  The following are tips for using your computer more efficiently in WIN-OS/2
  sessions:

  o   Current information for WIN-OS/2 window sessions in high-resolution video
      modes is available from CompuServe, the IBM National Support Center
      Bulletin Board System, the OS/2 Bulletin Board System, and IBMLINK*.

  o   If you are running Windows programs in WIN-OS/2 window sessions, you
      cannot have any statement in the AUTOEXEC.BAT file that prompts the user
      for input (for example, "Press any key to continue").

  o   Do not use the SETUP.EXE file shipped with Windows Version 3.0.  Instead,
      use the SETUP.EXE file shipped with WIN-OS/2 to ensure your environment
      is properly configured for OS/2 2.0.  Use the Selective Install program
      in OS/2 2.0 to change video device drivers for VGA, 8514, XGA, EGA, and
      CGA, and for mouse device drivers.  To start Selective Install, select
      the icon for OS/2 SYSTEM, then SYSTEM SETUP, then SELECTIVE INSTALL.

  o   To decompress Windows device drivers supplied by equipment manufacturers,
      use the EXPAND.EXE utility program for WIN-OS/2 located on OS/2 2.0
      Diskette 9.
      __________

  o   Windows Version 3.1 is not compatible with OS/2 2.0, so you cannot run it
      in a WIN-OS/2 session.  However, you can run Windows Version 3.1 in a
      separate partition.  Install Boot Manager, and partition your hard disk
      so that Windows Version 3.1 is in a partition separate from OS/2 2.0.
      Or, if you have DOS and Windows Version 3.1 already installed before you
      begin OS/2 2.0 installation, consider installing OS/2 2.0 Dual Boot.
      With Dual Boot, you can shut down OS/2 2.0 and start up DOS/Windows to
      run programs that require Windows Version 3.1.

  o   If a Windows program does not work correctly in a WIN-OS/2 session, it is
      likely that the program files were not all migrated properly.  To fix the
      problem, you can reinstall the program using a WIN-OS/2 full-screen
      session.  (Select RUN on the File menu of the Program Manager and use the
      command line there.)  Or, if you know the specific files that are needed,
      you can copy them from the \WINDOWS directory to the \OS2\MDOS\WINOS2
      directory.

  o   If you are running a WIN-OS/2 full-screen session and you have an 8514
      display, use DOS Settings to set VIDEO_8514A_XGA_IOTRAP to OFF and
      VIDEO_SWITCH_NOTIFICATION to ON.


  (C) Copyright IBM Corp. 1992                                              6-1









  o   If the VIDEO_SWITCH_NOTIFICATION setting is On, wait until you see your
      WIN-OS/2 desktop in a full-screen session before switching back to the
      OS/2 desktop.  If the session does not start successfully, close it, and
      then restart it.

  o   The value for VIDEO_SWITCH_NOTIFICATION should not be changed for an
      active WIN-OS/2 session.

  o    You cannot use the WIN-OS/2 Control Panel to change mouse buttons in
      WIN-OS/2 window sessions.  Change mouse button settings from the OS/2
      desktop to affect the WIN-OS/2 mouse buttons in the WIN-OS/2 window
      environment.  The WIN-OS/2 Control Panel can still be used for changing
      mouse buttons in WIN-OS/2 full-screen sessions.

  o   If you install the US English version of OS/2 2.0, and you want to change
      the system configuration to another country or language, run Selective
      Install to make the changes effective for OS/2.  To make the changes
      effective for WIN-OS/2, start WIN-OS/2 in a full-screen session, open the
      Control Panel, and use the INTERNATIONAL choice to make your changes.

  o   If you start a program in a WIN-OS/2 session and receive the message
      "FATAL ERROR 0X0401", ensure that all device statements are correct in
      OS2\MDOS\WINOS2\SYSTEM.INI.

  o   If you are running a WIN-OS/2 full-screen session with an XGA video
      device driver and your WIN-OS/2 icons are not clear, use the Control
      Panel to choose another color scheme for the WIN-OS/2 desktop.

  o   To improve performance, it is preferable to have only one server or
      client in a WIN-OS/2 session.

  o   If you have an XGA or 8514 display, keep the DDE server as an icon
      instead of opening it.  Also, set the DOS setting
      VIDEO_SWITCH_NOTIFICATION to On.


  USING CLIPBOARD AND DYNAMIC DATA EXCHANGE
  _________________________________________

  o   If you use the Clipboard Viewer to display data, cut, copy, or paste from
      a DOS, OS/2, or WIN-OS/2 program, ensure that the Clipboard Viewer is
      running before marking the text; otherwise, the copy might not be
      successful.

  o   The availability of Clipboard and Dynamic Data Exchange (DDE) functions
      can vary, depending upon the types of sessions you are running.

      -   In standard-mode full-screen WIN-OS/2 sessions, Clipboard and DDE
          default to Public.

      -   In real-mode full-screen WIN-OS/2 sessions, the default is Private.

      -   In WIN-OS/2 window sessions, Clipboard and DDE can only be Public.

  o   To disable Clipboard and DDE in an OS/2 session, do the following:


  6-2  Tips and Techniques









      1.  Create a WIN-OS/2 window or full-screen session, so that Clipboard
          and Data Update are started.  (Clipboard and Data Update are
          automatically started when you start a WIN-OS/2 session.)
      2.  On the OS/2 desktop, display the Window List.
      3.  Select CLIPBOARD and DATA UPDATE.
      4.  Display a pop-up menu by clicking mouse button 2 on CLIPBOARD or DATA
          UPDATE.
      5.  Select CLOSE.

  o   To share data between WIN-OS/2 sessions only, close Data Update and
      Clipboard in the OS/2 sessions.

  o   In a WIN-OS/2 window session, the Clipboard and DDE icons are not
      available.  You do not have access to the clipboard features.

      However, if you want to use a private clipboard in WIN-OS/2 window
      sessions, you can remove !CLIPWOS2 from the SYSTEM.INI file (in the
      OS2\MDOS\WINOS2 directory).  The statements involved are those that begin
      with:

           SAVDMApps=
           MAVDMApps=
           WOS2VDMapps=

      All three occurrences of !CLIPWOS2 must be removed.  It is advisable to
      back up the SYSTEM.INI file before making the changes, so that you can
      easily restore the original SYSTEM.INI if you decide to do so in the
      future.

      WARNING:  IF THE SYSTEM.INI FILE IS CHANGED INCORRECTLY, YOU MIGHT NOT BE
      ABLE TO USE WIN-OS/2.  IF YOU ARE NOT FAMILIAR WITH WINDOWS .INI FILES,
      YOU MIGHT WANT TO ARRANGE FOR A PERSON WHO HAS WINDOWS TECHNICAL
      EXPERTISE TO MAKE ANY CHANGES IN THE SYSTEM.INI FILE.

  o   To disable Clipboard and DDE in a full-screen WIN-OS/2 session, do the
      following:

      1.  Start WIN-OS/2.
      2.  Click mouse button 1 on the Clipboard icon to display the window
          menu.
      3.  Select CLOSE.
      4.  Respond to the confirmation message.
      5.  Repeat the previous steps to close the DDE Interchange Agent.

  o   If you experience slow performance when using a Windows program to copy
      data to the clipboard, consider the following information on improving
      performance.

      The clipboard uses delayed rendering, which means only the format name is
      given to the clipboard.  The actual data is rendered only when the PASTE
      menu choice is selected.  Many Windows programs use this scheme when they
      copy data to the clipboard.  However, to share data between WIN-OS/2 and
      OS/2 sessions, the WIN-OS/2 clipboard receives all data from the program
      that copied the data to the clipboard, and then sends the data to other


                                 Chapter 6.  WIN-OS/2 Application Programs  6-3









      sessions.  This process is time-consuming.  You can decide whether or not
      you want to share data between WIN-OS/2 sessions.

      If you do not want to share data, open the Clipboard icon in a WIN-OS/2
      full-screen session and turn off the PUBLIC CLIPBOARD choice on the
      OPTIONS menu bar choice; however, if you want to share some of the data
      between sessions, use the FILE EXPORT and IMPORT menu bar choices.

  o   If you are unable to paste data from the OS/2 clipboard to a WIN-OS/2
      session, you need to open the WIN-OS/2 session before you copy data from
      the OS/2 clipboard.  The WIN-OS/2 session starts the OS/2 clipboard,
      which will send the data to the WIN-OS/2 clipboard.  This problem will be
      fixed in a future release.

  o   If you cannot paste a bit map from the OS/2 clipboard to a WIN-OS/2
      session, the bit map might be too large, or the program might not
      understand the device-independent bit map (DIB) format of the file.  For
      example, icons created using the Icon Editor are not understood by some
      Windows programs, such as Microsoft Paintbrush.  If your WIN-OS/2 session
      is started first, you can view the bit map in the OS/2 clipboard;
      however, you cannot paste it.  The PASTE menu choice is grayed
      (unavailable).

  o   If you are running several programs concurrently (each doing Copy and
      Paste), you might receive from the clipboard pasted data that was
      supposed to go into another program.  Suppose you copy data to the
      clipboard using Program 1, but do not paste it into its destination right
      away.  While Program 1 is doing other work, you copy data from Program 2
      to the clipboard, and you do not paste that data either.  Later, you
      attempt to paste the Program 1 data from the clipboard.  However, the
      only data that is pasted is from Program 2, not Program 1.  This happens
      because the clipboard can hold data from only one cut or copy at a time.
      In this example, the copied data from Program 2 replaced the data from
      Program 1.

      To avoid having this problem, always paste the cut or copied data into
      its destination program before you cut or copy data from another program
      to the clipboard.

  o   Vertical scrolling in the OS/2 clipboard does not work.  It will be fixed
      in a future release.  In the meantime, you can use Page Down and Page Up.

  o   When a program copies several sources of data to a public clipboard in
      different formats, and if one of the sources creates a rendering problem,
      no data is sent to other WIN-OS/2 sessions.  In a future release, only
      the problem data will not be sent to the public clipboard.

  o   When a metafile is copied to the OS/2 clipboard, it is converted into a
      bit map, and then the image is enlarged.  Only the center of the image is
      in the clipboard viewer.  This will be fixed in future release.

  o   Metafiles in WIN-OS/2 and OS/2 are not compatible.  If you copy a
      WIN-OS/2 metafile without bit map information to a public clipboard, it



  6-4  Tips and Techniques









      is converted to a device-independent bit map (DIB) so that it can be
      exchanged with an OS/2 session.

  o   If you want to use dynamic data exchange (DDE) using the PASTE LINK
      choice on the File menu of a program, consider the following information.

      The clipboard should be set to Public.  The client and server must
      negotiate the data format to initiate the DDE link.  If this negotiation
      fails, some applications do not display any error message and no further
      action is taken.  If this happens, try another menu choice (for example,
      LINK), if available.

  CHAPTER 7.  PRINTING CONSIDERATIONS
  ___________________________________





  This chapter describes how to configure your printer hardware.  It also
  provides help when diagnosing printing problems.


  CONFIGURING YOUR COMPUTER FOR PRINTING
  ______________________________________

  On most Industry Standard Architecture (ISA) -- IBM refers to this
  architecture as AT bus -- parallel ports are configured using either
  dual-inline package (DIP) switches or jumpers.  Most of the systems and
  adapters purchased have literature that explains the interrupt request (IRQ)
  level and port setting for each port.  The following tables show standard
  parallel-port address and IRQ settings:

  +------------------+------------------+------------------+------------------+
  |                  |   AT BUS (ISA)   |       EISA*      |   MICRO CHANNEL  |
  +------------------+------------------+------------------+------------------+
  | LPT1             | 3BC/IRQ7         | 3BC/IRQ5 or IRQ7 | 3BC/IRQ7         |
  +------------------+------------------+------------------+------------------+
  | LPT2             | 278/IRQ5         | 378/IRQ5 or IRQ7 | 378/IRQ7         |
  +------------------+------------------+------------------+------------------+
  |                                     OR                                    |
  |                                                                           |
  +------------------+------------------+------------------+------------------+
  | LPT1             | 378/IRQ7         | 378/IRQ5 or IRQ7 | 378/IRQ7         |
  +------------------+------------------+------------------+------------------+
  | LPT2             | 278/IRQ5         | 278/IRQ5 or IRQ7 | 278/IRQ7         |
  +------------------+------------------+------------------+------------------+

  +------------------+------------------+------------------+------------------+
  |                  |   AT BUS (ISA)   |       EISA*      |   MICRO CHANNEL  |
  +------------------+------------------+------------------+------------------+
  | LPT1             | 3BC/IRQ7         | 3BC/IRQ5 or IRQ7 | 3BC/IRQ7         |
  +------------------+------------------+------------------+------------------+
  | LPT2             | 378/IRQ7         | 378/IRQ5 or IRQ7 | 378/IRQ7         |
  +------------------+------------------+------------------+------------------+
  | LPT3             | 278/IRQ5         | 278/IRQ5 or IRQ7 | 278/IRQ7         |
  +------------------+------------------+------------------+------------------+

  * Using IRQ5 or IRQ7 depends on the hardware interrupt level your Extended
  Industry Standard Architecture (EISA) parallel port supports.

  Dip switches and jumpers reside on the system board or adapter in your
  computer.  To change their configuration, do the following:

  1.  Turn off your computer.
  2.  Remove the parallel-port adapter.
  3.  Configure the system board or adapter by adjusting the DIP switches or
      jumpers to set the parallel port to one of the industry standard


  (C) Copyright IBM Corp. 1992                                              7-1









      combinations.  Ensure that other adapters are not configured to use the
      same IRQ level.  Sound, Musical Instrument Device Interface (MIDI), LAN,
      and serial adapters might be sharing these same hardware-interrupt levels
      and creating interference.

  For more information, refer to "Setting the Interrupt Request (IRQ) Level on
  an ISA System" on page 9-12 and "Interrupt Problems on an ISA System" on
  page 9-8.


  HARDWARE ADAPTERS AND IRQ CONFLICTS

  AT bus computers do not allow hardware-interrupt sharing; therefore, each
  adapter must be configured to a separate IRQ level to be able to work
  properly.  Some adapters, such as SoundBlaster, are factory configured to
  IRQ7, or their accompanying instructions recommend that you configure them to
  IRQ7.  This might be the same hardware-interrupt level as the first parallel
  port.  If you intend to print, this conflict must be resolved.  Refer to
  "Unable to Print" on page 7-7.  You might be able to use IRQ10 with
  SoundBlaster because it does not conflict with parallel ports (IRQ7 or IRQ5)
  or IRQ5 if LPT2 is not being used.  Refer to "Configuring Your Computer for
  Printing" on page 7-1 and "Setting the Interrupt Request (IRQ) Level on an
  ISA System" on page 9-12 for more information about possible parallel port
  and IRQ settings.

  Refer to the reference manual for your adapters to configure the IRQ levels
  for your parallel ports and other adapters in your system.


  PS/2 DIRECT-MEMORY-ACCESS PARALLEL PORTS

  If you have a Personal System/2(*) system that supports direct-memory-access
  (DMA) parallel ports, OS/2 2.0 can take advantage of it.  The current systems
  with a DMA parallel port include PS/2 models 56, 57, 80-A21, 80-A31, 90, and
  95.  If you have one of these systems, ensure that the parallel-port
  arbitration level is set to SHARED7 (enabled).  OS/2 2.0 will automatically
  take advantage of this feature; no additional OS/2 setup is required.  If you
  are an OS/2 Version 1.3 customer with Corrective Service Diskette 5054 (or
                                        ________________________________
  later) installed, and you have disabled the parallel-port arbitration level,
  you need to reenable it in order for OS/2 2.0 to take advantage of the
  feature.  Use the Reference Diskette shipped with the computer to view the
  system configuration, and then set the parallel-port arbitration level to
  SHARED7.


  SELECTING PRINTER DRIVERS
  _________________________

  The following section describes suggestions for using specific printers.








  7-2  Tips and Techniques









  CANON BUBBLE-JET PRINTER

  The following can help you select a driver for a a Canon** Bubble-Jet**
  printer to use with OS/2 2.0:

  o   The Bubble-Jet BJ10E can emulate an IBM Proprinter(*) x24E using the
                                                            _
      IBM42xx driver.
           __
  o   The Bubble-Jet BJC800 can emulate an Epson** LQ2550 using the OS/2 Epson
      driver.
  o   The Bubble-Jet LBP8 III+ can emulate an Epson LQ2550 or Proprinter x24E
                                                                         _
      using the appropriate driver.


  DESKJET, DESKJET+, DESKJET 500, AND DESKJET 500C PRINTERS

  If you want to use a Deskjet, DeskJet+, DeskJet 500, or DeskJet 500C printer,
  install the Epson driver and then select HP DESKJET 500.

  NOTE:  The HP DeskJet 500C will not produce color output using the HP DeskJet
         500 device support in the Epson printer driver.


  HP LASERJET PRINTER

  If you are going to install the OS/2 HP LaserJet printer driver over an
  existing driver, be sure to delete all the old .FNT files first.  Then,
  delete the printer driver from the OS/2 Workplace Shell printer object, and
  respond YES when asked if the driver files should be deleted from the hard
  disk.

  DIAGNOSING PRINTING PROBLEMS
  ____________________________

  This section describes the actions you can take to resolve some common
  printing problems.


  PRINTING IS SLOW

  If you have an AT bus computer and your parallel printer prints slowly under
  OS/2, DOS, and WIN-OS/2 sessions, your parallel-port address and
  hardware-interrupt levels are not configured correctly.  You need to
  reconfigure your hardware.  Refer to "Configuring Your Computer for Printing"
  on page 7-1.


  UNABLE TO PRINT

  If you encounter printing problems with parallel ports (for example, nothing
  prints), ensure that you have installed the appropriate printer driver for
  your model printer (see "Selecting Printer Drivers" on page 7-2).  If the
  printer driver is correct, check the following:

  o   Check that your parallel ports are configured properly.  Refer to
      "Configuring Your Computer for Printing" on page 7-1 for configuration
      settings.

  o   Verify that your printer cable meets parallel-port specifications. Some
      cables do not meet these specifications and can cause printing problems.
      (Cables that are longer than six feet in length are suspect.  The
      six-foot cable-length problem is more evident on high-speed
      microprocessor systems.)  Some cable manufacturers reduce the costs of
      their cables by not wiring all interface signals.  This might not have
      been a problem under DOS, because DOS does not make use of all the
      signals within the parallel-port interface.  However, some interface
      signals used to transmit data under OS/2 2.0 are not used when printing
      under DOS.

      You might need to purchase a new cable.  You might want to use an "IBM
      approved" cable -- one which has been verified as properly wired.

  o   If you still cannot print, and you are convinced it is not a
      printer-driver problem, interrupt problem, or cable problem, there might
      be a problem with your I/O adapter.  Some older parallel-port adapters
      fail to generate hardware interrupts; therefore, they will not work with
      versions of the OS/2 operating system.  These adapters usually work
      correctly under DOS, as DOS does not use hardware interrupts to print.
      The OS/2 2.0 operating system waits for the printer to send an interrupt
      when the printer is ready for more data.  If your adapter does not
      generate interrupts, it must be replaced if you want to print under OS/2
      2.0.  If your printer-buffer light illuminates, or prints one character
      and then displays an error message (or otherwise behaves erratically),
      you might have an interrupt problem.




                                       Chapter 7.  Printing Considerations  7-7









  PRINTER STOPS PRINTING

  If your DOS application sending PostScript** output stops printing, do the
  following:

  1.  Cancel the print job that caused the printer to stop printing.
  2.  Open the printer-object settings notebook to the Queue page.
  3.  Turn off the PRINT WHILE SPOOLING check box.
  4.  Resend the print job.


  PRINT JOB DAMAGED ON RETRY

  If you send a print job to an offline printer, and then retry the operation
  when the printer is online by responding to the Retry message, your job might
  be damaged.   To fix the problem, cancel the initial job, and resubmit it
  after resetting the printer.


  PRINTER WORKED UNDER DOS, BUT NOT UNDER OS/2 2.0

  If your printer worked under DOS, but does not work under OS/2 2.0, there is
  probably a problem with your hardware-interrupt level or printer cable.
  (Refer to "Unable to Print" on page 7-7.)


  PRINT JOB SPOOLED BUT DOES NOT PRINT

  The spooler will not print a job until the application closes the print-data
  stream.  Some DOS applications do not immediately close the print-data
  stream.  If you see your print job as an icon with an arrow pointing to the
  document in the Job Icon View window, the job will not print.  The arrow must
  point from the document to the print device.  This will not occur until the
  application closes the data stream.

  If the job does not print after 15 seconds, you might need to change a DOS
  setting.  By default, the PRINT_TIMEOUT DOS setting is turned ON and set to
  15 seconds.  If, after 15 seconds, your job does not print, adjust the
  setting.  (Refer to "Printing Starts Only When DOS Application Ends"
  regarding the LPTDD.SYS file.)


  PRINTING STARTS ONLY WHEN DOS APPLICATION ENDS

  If your DOS print job does not begin printing until the application is ended,
  the application has not closed the data stream.  Use the DOS_DEVICE DOS
  setting to load the C:\OS2\MDOS\LPTDD.SYS device driver.  Then, the
  PRINT_TIMEOUT DOS setting can be used to close the print job without having
  to exit the application.







  7-8  Tips and Techniques









  PRINT JOB SPLIT INTO SEVERAL SPOOL FILES

  If your DOS application print job is split into several spool files, you
  might need to disable the spooler to correct the problem.  Some applications
  open and close the printer data stream for every character, line, or page.
  Disabling the spooler (using the Spooler object in the System Setup folder)
  is one way to correct this problem.  Another alternative is to upgrade the
  application by contacting the manufacturer.  If the problem occurs with
  complex printouts, you might increase the DOS setting PRINT_TIMEOUT value.


  CAN PRINT FROM DOS APPLICATION, BUT CANNOT PRINT ELSEWHERE

  If you are printing from a DOS application, but are unable to print elsewhere
  until you end the DOS application, your DOS application is accessing the
  parallel-port hardware directly.  OS/2 2.0 prevents two or more applications
  from simultaneously accessing the same parallel-port hardware.  The second
  application must wait for the first application to end, even if the second
  application is the OS/2 print object.


  PRINTER WORKED UNDER WINDOWS, BUT NOT UNDER OS/2 2.0

  o   If your printer worked under a Windows operation, but does not work after
      installing OS/2 2.0, delete the printer driver and reinstall it under
      WIN-OS/2 using the WIN-OS/2 Control Panel.

  o   If printing from a WIN-OS/2 session is slow, but acceptable everywhere in
      the system, you might need to set the priority level higher using the
      Options menu in the WIN-OS/2 Print Manager.


  PRINTING FROM A WIN-OS/2 SESSION
  ________________________________

  The following section describes considerations for customizing your system to
  print from a WIN-OS/2 session.


  LPTX AND LPTX.OS2 PORT CONSIDERATIONS

  If your printer is connected to LPTx or LPTx.OS2, be sure that the OS/2
                                     _       _
  spooler is active and the WIN-OS/2 printer does not use the Print Manager.
  (Disable using the Printer icon in the WIN-OS/2 Control Panel.)  When the
  OS/2 spooler is active, WIN-OS/2 applications print directly to the OS/2
  spooler.  Therefore, multiple print jobs can be spooled from one WIN-OS/2
  session or multiple WIN-OS/2 sessions.  This does not apply to serial
  printers, because there is no spooling for COM devices to the OS/2 spooler
  (only to WIN-OS/2 Print Manager).  If you are using LPTx but are unable to
                                                         _
  print from any other session, you must use LPTx.OS2 for WIN-OS/2 printing.
                                                _
  If you are printing to a redirected port, you must use LPTx.OS2.
                                                            _






                                       Chapter 7.  Printing Considerations  7-9









  CONFIGURING AN LPT3.OS2 DESTINATION

  To enable support for LPT3.OS2, you need to configure an LPT3.OS2 destination
  that you can select from the ports listbox in the WIN-OS/2 Control Panel.
  You must shut down your WIN-OS/2 session and edit the
  C:\OS2\MDOS\WINOS2\WIN.INI file.  You need to add a "LPT3.OS2=" line
  following the "LPT2.OS2=" line in the ports section of the file.  After
  saving the file, you can start the WIN-OS/2 session and Control Panel and
  then select the LPT3.OS2 destination.


  INSTALLING THE IBM 4029 LASER PRINTER

  o   If you are installing the IBM4029 Windows PostScript printer driver for
      use in WIN-OS/2 sessions, do the following to avoid an invalid entry in
      the WIN.INI file:

      1.  Select CONTROL PANEL in the WIN-OS/2 session.
      2.  Select PRINTERS.
      3.  Select ADD PRINTER.
      4.  Select UNLISTED PRINTER from the list of printers.
      5.  Insert Printer Driver Diskette 4 in drive A.
                 _________________________
      6.  In the Files and Directories window, select A.
      7.  Select PSCRIPT.DRV from the files list.  (This installs the
          PostScript driver.)
      8.  Select CONFIGURE.
      9.  Select the appropriate port.
      10. Select SETUP.
      11. Select IBM4029 (17 font, 600 Dpi) from the list of printers.
      12. Select OK several times to remove the open windows.
      13. Exit the Control Panel.
      14. Save any changes; then exit the WIN-OS/2 session.

  o   If you have problems printing with a 4029 printer in a WIN-OS2 session,
      change the WIN.INI file in the OS2\MDOS\WINOS2 directory.  Several lines
      in the file refer to the 4029 printer; for example:

          IBM 4029 v52.3 (17 Fonts, 600 Dpi)

       Now change the comma (,) to a colon (:) as follows:

          IBM 4029 v52.3 (17 Fonts: 600 Dpi)


  NETWORK PRINTING
  ________________

  o   To improve the performance of viewing the contents of a network printer
      object, use a long refresh interval or set the interval to 0 (no
      refresh).

  o   If you move the network object from the desktop to another folder, the
      network printer-object template will not appear the next time you start
      the system. To make it reappear, move the network object back to the
      desktop and restart the system.


  7-10  Tips and Techniques









  o   If you are unable to print from a DOS session to an LPT port that is
      redirected to a network printer, you might need to use the LPTDD.SYS
      device driver.  (Refer to "Printing Starts Only When DOS Application
      Ends" on page 7-8 for more information.)

  CHAPTER 8.  VIDEO GRAPHICS SUPPORT
  __________________________________





  OS/2 2.0 fully supports EGA, and VGA.  Because of the graphical user
  interface provided by the Workplace Shell, using OS/2 2.0 in CGA mode will be
  difficult and is not recommended.  However, applications designed for CGA
  mode are supported and can be run even when OS/2 2.0 is running in EGA, VGA,
  or SVGA mode.  The OS/2 installation program will correctly configure OS/2
  2.0 and WIN-OS/2 drivers for the 8514 display and the XGA* mode.

  Resolutions above VGA (640 x 480 x 16 colors) are referred to as Super VGA
  (SVGA).  The implementation of SVGA varies widely and requires different
  device drivers for different resolutions, as well as for different adapters
  and systems.  All SVGA adapters are supported in VGA mode with the VGA driver
  provided with OS/2 2.0.


  SUPER VGA
  _________

  The base video system and virtual display device driver in OS/2 2.0 have been
  enabled for some of the most popular SVGA chips and adapters.  This support
  is required to switch between OS/2 Presentation Manager, DOS, or WIN-OS/2
  applications.  Because of the many implementations and video modes, a limited
  number of video boards have been tested.

  The following Super VGA adapters have been tested and found to work with OS/2
  2.0 for DOS applications that make use of SVGA modes:

  o   Orchid** ProDesigner IIs by Orchid Technology (ISA and MCA versions)
  o   Trident TVGA by Trident Microsystems, Inc. (8900b and c levels)
  o   STB PowerGraph** VGA by STB Systems, Inc.
  o   Video Seven VRAM II, by Video Seven
  o   Boca Super VGA by Boca Research** Inc.
  o   VGAWONDER XL** series by ATI Technologies, Inc.
  o   Paradise VGA Professional by Western Digital Imaging

  VGA support is designed to be generic for the Trident, Tseng**, ATI,
  Headland, and Western Digital chipsets.  It is likely that there are many
  more adapters which are supported that have not been tested.

  The 8514/ULTRA** by ATI must be installed as an 8514 and as a primary
  display; it will default to high-resolution mode.  You need to edit the
  following statement in your CONFIG.SYS file:

       DEVICE=\OS2\MDOS\VVGA.SYS

  to

       DEVICE=\OS2\MDOS\VSVGA.SYS




  (C) Copyright IBM Corp. 1992                                              8-1









  Contact the manufacturer of your computer or SVGA video adapter to obtain
  device drivers and installation instructions if you want to run Windows or
  OS/2 applications in SVGA modes.  Information about SVGA support will be
  available on CompuServe, the National Support Center Bulletin Board System,
  the OS/2 Bulletin Board System, as well as many video-board and system
  manufacturers' bulletin boards.

  Do NOT run the video-adapter test utility programs in OS/2 2.0 unless the
  manufacturer has explicitly verified that they run in OS/2 2.0.

  Some video adapters require that the computer's DOS BIOS initialize the video
  adapter correctly.  If you have one of these adapters, screen text might
  appear distorted in an OS/2 full-screen command prompt.  To remedy this,
  start a DOS full-screen session, type EXIT, and then switch back to the OS/2
  full-screen session; the text should appear normal.

  To automate this process, you can create a DOS batch file to run when you
  start your computer.  Add the following statement to STARTUP.CMD:

     START /FS /DOS DOSFS.BAT

  Create the file DOSFS.BAT and place the following statement in it:

     EXIT


  SVGA ON UTILITY PROGRAM

  If you have one of the video adapters listed on the previous page and want to
  run DOS or Windows applications that make use of SVGA, you must turn on OS/2
  2.0 SVGA support.  The OS/2 Installation program detects the type of video
  chip in the system; it cannot detect the type of adapter or system board that
  the video chip has been implemented on.  You must determine that you have a
  supported configuration, and then explicitly enable SVGA.

  To enable SVGA, type the following at a DOS full-screen command prompt:

     SVGA ON

  Then restart the system.

  NOTE:  This does not apply to IBM PS/2 Micro Channel computers.


  OS/2 SVGA VIDEO FILES

  o   OS2\SVGADATA.PMI

      This file indicates that SVGA support has been enabled with SVGA ON.  The
      file contains data on the following:

      -   The video chipset of your SVGA adapter.
      -   The SVGA modes from the supported list your adapter is capable of
          setting.  The list of supported modes is:


  8-2  Tips and Techniques









          -   640 x 480/256 colors
          -   800 x 600/16  colors
          -   800 x 600/256 colors
          -   1024 x 768/16 colors
          -   1024 x 768/256 colors
          -   132 x 25 text
          -   132 x 43 or 44 text
      -   The values in the video registers when the adapter is in each mode.
          This data is used by the OS/2 operating system to save and restore
          the registers to their proper state when switching between sessions
          with different SVGA modes set.  This data file must be generated by
          typing SVGA ON at a DOS full-screen command prompt, because SVGA ON
          sets all the possible modes using the BIOS of the video adapter, and
          then reads out the values of the registers into the .PMI file.  If
          SVGA ON is run from a DOS window, the video virtualization of the
          operating system takes over, and the BIOS does not set the SVGA modes
          properly.

      Even though two systems have the same video adapter, the same
      SVGADATA.PMI file does not work in both.  The SVGADATA.PMI file has to be
      specific to each adapter/display setup.

  o   OS2\SVGA.EXE

      This is the utility program that generates the .PMI file and places it in
      the OS2 subdirectory.  The syntax is:

        SVGA ON|OFF|STATUS

      where ON creates the OS2\SVGADATA.PMI file and enables SVGA support, OFF
      deletes the .PMI file, and STATUS returns the chipset type that your
      adapter appears to be to the operating system.

  o   OS2\DLL\DISPLAY.DLL

      This file determines what video resolution the desktop uses.  This is the
      Presentation Manager display driver.  The equivalent file on a Windows
      system is the VGA.DRV (in the case of VGA) file.  For the first release,
      SVGA systems will have a VGA display driver installed on their system.
      Already, SVGA drivers are available from most of the main adapter
      manufacturers.

  o   OS2\DLL\BVHSVGA.DLL

      This file is the Base Video Handler for the OS/2 operating system.  Any
      OS/2 application that sets a video mode calls this DLL.  In most cases,
      however, the only application that sets any video modes is the
      Presentation Manager display driver and the MODE.EXE utility program (for
      setting 132-column modes).  The first time this DLL would be called is
      after the OS/2 bit-map logo appears (PM starts up then).  This DLL is
      specified in the CONFIG.SYS file as the following:

        SET VIO_VGA=DEVICE(BVHVGA,BVHSVGA)



                                        Chapter 8.  Video Graphics Support  8-3









      BVHVGA is used to set, save, and restore VGA modes; BVHSVGA is used for
      SVGA modes.

  o   OS2\MDOS\VSVGA.SYS

      This is the virtual video device handler for DOS sessions.  All calls to
      change the video mode from a DOS session are handled through this driver.
      The job of this driver is to allow the user to set an SVGA mode, and when
      the user switches away, to save the current state of the video adapter
      (its registers and its video RAM).  Then, when the user returns to the
      DOS session, it restores the video adapter to its previous state.  When
      there is no .PMI file (SVGA is OFF), this driver acts like a VGA driver,
      except for adapter-specific code which ensures the VGA modes work
      correctly on the SVGA adapter.  Therefore, even if you do not want SVGA,
      you will probably want VSVGA.

  o   OS2\MDOS\WINOS2\SYSTEM\VGA.DRV
      OS2\MDOS\WINOS2\SYSTEM\SWINVGA.DRV

      These are the WIN-OS/2 full-screen and WIN-OS/2 window session drivers,
      respectively.  They determine which resolution WIN-OS/2 uses.


  ADDITIONAL SVGA SUPPORT INFORMATION

  o   Over time, more display adapters and PC systems that offer SVGA will be
      tested.  Refer to the bulletin boards mentioned previously, or to the
      manufacturers, for the latest support information.

  o   To make use of SVGA modes, you also must install Windows and Presentation
      Manager video display drivers.

  o   If you experience display errors on an SVGA-enabled system, try disabling
      SVGA support by typing SVGA OFF at a command line.  This will delete the
      SVGADATA.PMI file.  Then restart your system.

  o   In some SVGA displays, if you switch to the PM desktop while the screen
      is still drawing, you might experience display errors on the PM desktop.
      Switch back to the SVGA screen, allowing the drawing to complete, and
      then switch back to the PM desktop.

  o   Some screen resynchronization problems might exist in DOS or WIN-OS/2
      full-screen sessions.  The problem is with how some SVGA adapters handle
      switching.  IBM has created a new VSVGA.SYS file to correct this.
      Specifically, the problem occurs most frequently with Tseng chipsets.
      Video adapters using the Tseng ET4000 chipset with batch #TC6059AF have
      been identified as having this problem.  The VSVGA.SYS file dated 4/8/92
      or later should solve this problem.

  o   In the event of a TRAP000E error message when opening a DOS or WIN-OS/2
      session on systems with 4MB of memory and SVGA adapters, you need to
      obtain the VSVGA.SYS driver replacement from IBM.




  8-4  Tips and Techniques









  o   In the event of a SYS3176 message when starting a DOS or WIN-OS/2 command
      prompt, try setting the HW_ROM_TO_RAM setting in the session to ON or
      changing the DOS_RMSIZE parameter in the session to 624 from the default
      640.  If this does not work, the VSVGA.SYS fix from IBM might resolve the
      problem.

  o   A virtual desktop is a Presentation Manager display driver that uses all
      of the adapter's video memory to store a desktop that is bigger than what
      is actually displayed.  You could have 1024 x 1024 of desktop space, with
      only 640 x 480 being displayed on the screen.  You move to other portions
      of the desktop by dragging the mouse to the edge of the screen, which
      scrolls the desktop.  Because of the way OS/2 2.0 is designed, this is an
      extremely quick operation and will be very smooth, even on the slowest
      video adapters.  The PM driver must be coded to support virtual desktops,
      and Trident is currently the only chipset to support it.

  o   Trident supports OS/2 2.0 and has SVGA presentation drivers available for
      their SVGA boards.  Trident's support number is 415-691-9211.  They also
      have support bulletin boards where these drivers are available.  For the
      West Coast, the number is 415-691-1016 and for the East Coast, the number
      is 203-483-0348.

  o   Orchid is working on OS/2 drivers for their video adapters.  For more
      information, you can reach Orchid's bulletin board service at:

      -   510-683-0327 for 2400 baud, parameters n,8,1
      -   510-683-0555 for 9600 baud, parameters n,8,1
      -   ATI now has SVGA drivers for OS/2 2.0.  Information is available
          using the ATI bulletin board service:

              416-756-4591 (2400 baud, N, 8, 1)


          The file names are ATIOS213.ZIP and WIN31ACC.ZIP.
      -   A WIN-OS/2 window session has the ability to run Windows Version 3.0
          programs on the desktop.  The way it is achieved is by making a place
          in the desktop that the WIN-OS/2 window session driver writes to.
          Special code must be put into both the window session driver and the
          display driver to support this.  Trident has produced 800 x 600/16
          WIN-OS/2 window session drivers, and has been the only one to produce
          SVGA support for WIN-OS/2 window sessions so far.
      -   Questions about OS/2 support for adapters based on the S3 or TI**
          chipsets have been asked.  Adapters which are coprocessed are the
          fastest, but also take the longest to develop software for.  No
          manufacturers have announced dates yet for support of any of these
          adapters.  You might want to contact the manufacturer for further
          information.
      -   In the event of some corruption when returning to a WIN-OS/2
          full-screen session, set your VIDEO_SWITCH_NOTIFICATION in the DOS
          Settings to ON.
      -   Even in VGA, games in a DOS full-screen session are not optimized.
          Set your VIDEO_RETRACE_EMULATION in the DOS Settings to OFF.
      -   Some DOS applications in a window have color corruption.  This is a
          limitation of the VGA desktop.  The color palette of the DOS session


                                        Chapter 8.  Video Graphics Support  8-5









          has to be translated to PM, and the 640 x 480/16 desktop does not
          offer enough colors to do a good translation.  The best solution is
          to use a 256 color PM driver or run the application in a DOS
          full-screen session.
      -   The graphics of some applications are corrupted when displayed in a
          window.  These applications are probably using a nonstandard VGA mode
          that the adapter can support, but that OS/2 2.0 does not.
      -   When you have SVGA ON, you can:
          -   Use 132 column modes in an OS/2 full-screen session
          -   Take a window with an SVGA image in it and paste it to the
              Clipboard
      -   To enable the Windows 3.0 SVGA drivers in WIN-OS2, update the
          SYSTEM.INI file to point to a new Windows display driver, or just
          copy over the VGA.DRV in the OS2\MDOS\WINOS2\SYSTEM directory.  Keep
          in mind, however, that a Windows session in SVGA mode will only work
          if you have set SVGA ON.
      -   Many different SVGA boards have different interfaces and chipsets,
          each with their own characteristics.  Some boards perform better with
          SVGA OFF.


  DUAL DISPLAYS
  _____________

  In multiple XGA configurations, when you switch from DOS to the desktop, your
  system will not save and restore the hardware registers.

  If your machine has an 8514/ULTRA adapter and an OS/2 2.0 supported SVGA
  adapter, you will need to change the DEVICE= statement in your CONFIG.SYS
  file from VVGA.SYS to VSVGA.SYS.


  LAPTOP LCD OR MONOCHROME PLASMA DISPLAYS
  ________________________________________

  To change the color schemes for OS/2 system windows and create a more
  readable display image, change the Scheme Palette as follows:

  1.  Use your Reference Diskette or hardware Setup program to set your
      hardware to VGA color, if possible.
  2.  Open the System folder.
  3.  Select SYSTEM SETUP.
  4.  Select SCHEME PALETTE.
  5.  Select the monochrome scheme in the right-hand column.

  This procedure will optimize the color scheme for gray-scale usage, and also
  provide a good set of colors for a VGA desktop presentation.


  INAPPROPRIATE FONT METRICS
  __________________________

  Several fonts have been enhanced in OS/2 2.0.  Some existing applications use
  inappropriate font metrics to scale their text.  In some cases, the text
  becomes clipped because it no longer fits in the available space.

  WIN-OS/2 WINDOW AND FULL-SCREEN SESSIONS
  ________________________________________

  When running a WIN-OS/2 full-screen session with an 8514 adapter in
  high-resolution (8514.DRV) mode, do not switch to a different session while
  an application is updating the screen or displaying the hourglass.

  The following is a procedure for enabling WIN-OS/2 full-screen sessions to
  run in high-resolution (XGA) mode while the Workplace Shell desktop and
  WIN-OS/2 window sessions run in medium-resolution (VGA) mode.  The procedure
  assumes you are not familiar with the SYSTEM.INI and WIN.INI files.

  Follow the instructions very carefully.  Otherwise, you could cause your
  WIN-OS/2 sessions, both window and full-screen, to become inoperable.

  1.  Install OS/2 2.0 for medium-resolution VGA.

      The next step requires that you make backup copies of your SYSTEM.INI and
      WIN.INI files.  DO NOT SKIP THIS STEP.  It is assumed that you have a
      diskette or tape backup copy of your system; instructions follow for a
      backup of the directory only.

  2.  Back up the SYSTEM.INI and WIN.INI files.

      Open an OS/2 Window from the Command Prompts folder in the OS/2 System
      folder.  At the C prompt, type the following and press Enter:

         CD\OS2\MDOS\WINOS2
         COPY WIN.INI WIN.BAK
         COPY SYSTEM.INI SYSTEM.BAK

      Before making changes to the files, be sure the desired high-resolution
      Windows device drivers and fonts are loaded in the system.

  3.  Check the \OS2\MDOS\WINOS2\SYSTEM directory for the desired
      high-resolution display device driver.  In this example, the XGA.DRV
      device driver is used.  Checking this directory reveals that this device
      driver is not loaded.  (The device driver might be loaded already, if the
      system was installed in high-resolution mode and then Selective Install
      was run to return to VGA mode.)

      For XGA mode, the diskettes need to be searched for WINXGA and *G.FON.
      The following shows the sequence of entries:

         DIR A:WINXGA
         DIR A:*G.FON

      No XGA drivers were on this diskette, but one of the font files was.
      Although the font file is not in a bundle of files, it is still in packed
      format and must be unpacked.

      The files are packed with their standard target directory coded into the
      packed file.  To copy the file to the system disk in the proper
      directory, just run the Unpack utility program.



                                        Chapter 8.  Video Graphics Support  8-7









         UNPACK A:SYMBOLG.FON

      This procedure continues until all of the scalable fonts are unpacked.
      These fonts are:

      o   SYMBOLG.FON
      o   TMSRG.FON
      o   COURG.FON
      o   HELVG.FON

      Eventually the WINXGA file is found by the dir a:WINXGA search.  It
      contains the WIN-OS/2 XGA.DRV and three XGA fonts.

         UNPACK A:WINXGA

      With all of the required driver and font files on the system disks, the
      next step is to modify the SYSTEM.INI file.

  4.  Edit the SYSTEM.INI file and find the following line:

         display.drv=vga.drv

  5.  This line specifies the device driver WIN-OS/2 is to use in full-screen
      sessions.  Change this line to point to the high-resolution device driver
      that was unloaded in the steps above. In this example, the device driver
      is XGA.DRV.  The modified line should look like the following:

           display.drv=xga.drv

      Both SYSTEM.INI and WIN.INI have font entries that must be changed.  In
      SYSTEM.INI, these entries are:

           fixedfor.fon=vgafix.fon
           oemfonts.fon=vgaoem.fon
           fonts.fon=vgasys.fon

      For XGA mode, these entries must be changed to:

           fixedfor.fon=xgafix.fon
           oemfonts.fon=xgaoem.fon
           fonts.fon=xgasys.fon

      In WIN.INI, the entries:

           Symbol 8,10,12,14,18,24 (VGA res)=SYMBOLE.FON
           Helv 8,10,12,14,18,24 (VGA res)=HELVE.FON
           Tms Rmn 8,10,12,14,18,24 (VGA res)=TMSRE.FON
           Courier 10,12,15 (VGA res)=COURE.FON

      must be changed to:






  8-8  Tips and Techniques









           Symbol 8,10,12,14,18,24 (XGA res)=SYMBOLG.FON
           Helv 8,10,12,14,18,24 (XGA res)=HELVG.FON
           Tms Rmn 8,10,12,14,18,24 (XGA res)=TMSRG.FON
           Courier 10,12,15 (XGA res)=COURG.FON

  When these changes have been made and the .INI files saved, the system is
  ready for running Windows applications in WIN-OS/2 window sessions (VGA mode)
  and WIN-OS/2 full-screen sessions (high-resolution mode).

  For 8514 displays, you must delete the following line from the CONFIG.SYS
  file:

       DEVICE=C:\OS2\MDOS\V8514A.SYS

  For 8514 displays, the files to find are:

      WIN8514 (contains 8514.DRV, 8514SYS.FON, 8514OEM.FON, and 8514FIX.FON)

      COURF.FON

      TMSRF.FON

      HELVF.FON

      SYMBOLF.FON

  | Windows application program developers should note that their debuggers   |
  | work in full-screen sessions only.  If you have a dual-display setup      |
  | (8514+VGA), install OS/2 2.0 for the 8514 as primary display with no      |
  | secondary display.  This will allow your Turbo Debugger for Windows (TDW) |
  | or CodeView for Windows (CVW) programs to run in a full-screen session on |
  | the VGA display while the WIN-OS/2 session runs full screen on the 8514.  |
  | For CVW, make sure to use the /8 option.  Quick C runs on the same        |
  | display as WIN-OS/2.  If you use Quick C, you don't need a special video  |
  | configuration.                                                            |
  |                                                                           |
  | Installing OS/2 2.0 in this way will allow PM to run on the 8514, and     |
  | your full-screen debugger to run on the VGA.  It also will provide a      |
  | "stereo" effect for all full-screen sessions; both the 8514 and VGA       |
  | displays will show the same picture, unless a full-screen application     |
  | takes advantage of video-specific features.                               |
  |                                                                           |

  CHAPTER 9.  HARDWARE SUPPORT
  ____________________________





  The following sections provide information about hardware device support in
  OS/2 2.0.


  PERSONAL COMPUTER MANUFACTURER SYSTEMS
  ______________________________________

  OS/2 2.0 is supported on personal computers with an 80386 SX (or compatible)
  or later microprocessor, with at least 4MB of memory and a 60MB hard disk
  with 15MB -- 30MB of free space.

  IBM is currently testing personal computer manufacturer (PCM) systems for
  compatibility with OS/2 2.0.  The compatibility test verifies 18 key
  functions of OS/2 2.0.  Test results are based on selected model
  configurations provided by the manufacturers.  While testing is continuing,
  current compatibility information about tested systems is available through
  your dealer or Marketing Representative, as well as through the following
  online services:

  o   Prodigy**, Jump Computer Club, in Windows and OS/2 topic. (To join
      Prodigy, call 1-800-Prodigy.)

  o   CompuServe, G IBMOS2, in Library 17, PCMTAB.TXT.  (To join CompuServe,
      call the appropriate phone numbers for your area, or Membership Service
      at 1-800-848-8199, and ask for representative 239.)

  o   IBM National Support Center Bulletin Board System (NSC BBS).  This
      service is available 24 hours a day, on a toll-call basis, with no access
      charge, to anyone in the world who has a modem,
      asynchronous-communication programs, and a switched telephone line.  (The
      modem should be set for 8 data bits, 1 stop bit, no parity, and the
      standard transmission speed from 1200 to 9600 baud.)

      To access the NSC BBS, call (404) 835-6600.

  o   IBMLink.  Eligible customers can obtain installation and usage assistance
      through IBMLink Question Support.  To obtain information about
      eligibility, contact your local Branch Office or Marketing
      Representative.

  NOTE:  The compatibility test information is provided for information
         purposes only.  IBM MAKES NO WARRANTY, EXPRESS OR IMPLIED, WITH
         RESPECT TO THE OPERATION OF THE PERSONAL COMPUTERS LISTED THROUGH THE
         ABOVE SOURCES.

  SCSI ADAPTERS
  _____________

  o   ProCom+ SCSI disk adapters (Micro Channel) are not supported by OS/2 2.0.
      You should contact the manufacturer for any details on OS/2 support.

  o   Some SCSI adapters have jumper pins which can be set to either
      synchronous or asynchronous mode. There have been noted problems such as
      no icons appearing or slow hard disk performance.  This can be attributed
      to the SCSI adapter and hard disk not being set to the same synchronous
      or asynchronous settings.  Either way, they must match.  Be sure these
      are set properly.

  o   The early versions of the IBM 16-bit SCSI adapters might experience
      problems and report, erroneously, that the device is not functioning.
      This can be corrected by replacing the SCSI adapter with an adapter with
      updated microcode.


  ADAPTEC AND FUTURE DOMAIN SCSI DEVICE DRIVERS

  Device support for the following Adaptec and Future Domain SCSI adapters is
  shipped with OS/2 2.0.  When any of the following adapters is installed in a
  workstation, its presence is normally detected automatically, and the
  appropriate device support is subsequently installed.

  For reference, the names of the device drivers that support each adapter are
  provided in the following table.

  +-------------------------------------+-------------------------------------+
  | SCSI ADAPTER OR INTERFACE           | DEVICE DRIVER                       |

  For the Adaptec 1542B SCSI card to run properly, set the default data rate to
  5.

  The TMC-850/860/875/885 and TMC-850IBM adapters will not be detected when the
  adapter's BIOS is disabled.  To install this support in your system follow
  these steps:

  1.  Locate Installation Diskette 8, which contains the file DASDDRVS.
             _______________________

  2.  Insert the diskette in drive A.

  3.  Change the current directory to the root directory of the startup drive.

  4.  Type:

          UNPACK A:DASDDRVS \OS2 /N:xxxxxxxx.ADD

      Where xxxxxxxx.ADD is the file name of the device-driver file you want to
            ____________
      install.

  5.  Add the following line to the CONFIG.SYS file:

         BASEDEV=xxxxxxxx.ADD

  6.  Restart the system.


  OS2SCSI.DMD DEVICE DRIVER

  Earlier versions of the OS/2 operating system used the device driver
  SCSI.SYS.  This has been replaced by OS2SCSI.DMD.  OS2SCSI.DMD is provided in
  the OS2 directory of the startup partition.  Replace the old CONFIG.SYS entry
  "DEVICE=SCSI.SYS" with "BASEDEV=OS2SCSI.DMD."  Normally, this is done
  automatically, but inspect your CONFIG.SYS file if you suspect SCSI problems.

  The OS2SCSI.DMD device driver is required for a number of SCSI CD-ROM
  devices, SCSI read/write optical devices, and SCSI tape devices.


  SCSI CD-ROM SUPPORT

  The SCSI CD-ROM support built into OS/2 2.0 has some manufacturer-specific
  dependencies at this time.  Support has been verified for IBM and Toshiba
  SCSI CD-ROM drives.  If your CD-ROM is either SCSI with no other devices
  attached or is non-SCSI, you might get it to work by using an external DOS
  session (VMBOOT by using the DOS Program setting, DOS_STARTUP_DRIVE ).
  Information about the support and verification of additional manufacturers'
  drives will be made available at a later date.


                                              Chapter 9.  Hardware Support  9-3









  SCSI REMOVABLE MEDIA SUPPORT

  Full-function support is not yet available for SCSI hard disk drives that are
  removable media.  Examples of this class of device include the Bernoulli
  drives manufactured by Iomega**, and the removable-media drives manufactured
  by SyQuest Technology.

  Although OS/2 2.0 recognizes these drives, it will treat them as large
  diskettes.  You will be able to format for the FAT file system only.  You
  will not be able to partition or start up from this medium, and partitioned
  removable-media drives will not be recognized.

  If the IBMINT13.I13 driver is used to control these units, the drive will be
  treated as a hard disk.  In this case, the cartridge must be in the drive at
  startup time.  Use the SHUT DOWN choice on the desktop pop-up menu to remove
  the cartridge from the drive.

  Bernoulli 44MB and 89MB drives work if connected to Adaptec, Future Domain,
  IBM, or any adapter other than the Bernoulli adapter.  The drive will work as
  a large diskette but cannot be used as a startup drive.  Customers should
  call Iomega for status on an update for their adapter.

  If Seagate SCSI controller model ST-01 or ST-02 is present, it must be the
  only drive controller present.  Conflicts exist between this controller and
  MFM and RLL hard disk controllers.

  If you experience some problems with a Western Digital WD7000 SCSI adapter,
  contact Future Domain for assistance.

  AMI AND CEI SCSI ADAPTERS

  AMI Fast Disk and AMI Fast Disk II SCSI adapters are incorrectly recognized
  as Adaptec adapters.  The CEI Cumulus C5640B SCSI Micro Channel adapter has
  the same problem.  If you have one of these adapters in your system, do the
  following:

  o   At the final restart after the installation is completed, delete from the
      CONFIG.SYS file any line with "BASEDEV=AHA1xxx.ADD" (where x can be any
                                                 ___             _
      character).
  o   Ensure the line "BASEDEV=IBMINT13.I13" appears in the CONFIG.SYS file.
      This line should have been placed there by system installation.


  ALWAYS TECHNOLOGY SCSI

  If you are experiencing OS/2 problems either at installation time or after,
  (such as a TRAP 000D error) and your system has an Always Technology IN-2000
  SCSI adapter, the BIOS on the adapter might be the problem.  If the BIOS
  revision level is 3.06A or 3.20 (as shown during the system self-test), you
  should get the BIOS on the adapter upgraded.  The current BIOS level is
  VCN:1-02 and works with OS/2 2.0.  If you require this upgrade, you might
  also need an upgrade to a companion 8-pin serial PROM chip which must have a
  revision level of 2.5-2.7.  Always Technology support can be reached at
  818-597-9595.


  ADDITIONAL DEVICE SUPPORT INFORMATION
  _____________________________________

  The following contains useful information about OS/2 2.0 support for the
  specified devices.


  BERNOULLI DEVICE DRIVERS

  If you are experiencing a problem installing your new Bernoulli device
  driver, call the Iomega Corporation support group at 1-800-456-5522 and ask
  for an OS/2 technician.







  9-6  Tips and Techniques









  HP SCANJET

  If you receive an error message saying that you cannot access your HP
  scanner, and you are using an ISA (AT-style) bus machine, your adapter
  switches need to be set to 1010.

  If you are using a PS/2 computer, you must use the Reference Diskette to set
  the adapter to ROM addresses C8000 -- CBFFF and I/O addresses 268 -- 26F.  In
  both cases, you also need to set the DOS Setting for the DOS session for
  EMS_FRAME_LOCATION to Auto.


  TAPE DRIVES

  The following describes IBM and non-IBM tape drives that work in conjunction
  with OS/2 2.0.


  Adapter or SCSI

  The only tape drives that have been tested at this point are IBM tape drives.
  If no other device is connected to the SCSI bus on its adapter or the tape
  adapter, then you might be able to get your drive to work in an external DOS
  (VMBOOT) session.

  If the tape drive worked under OS/2 version 1.x and the device is written to
                                                _
  ASPI, IBM is currently working on support for your device.  IBM does not
  provide third-party device drivers for peripherals.  Refer to your peripheral
  manufacturer for OS/2-specific support.


  Diskette Based

  IBM or IRWIN tape drives are supported.  Programs are PMTAPE or PS2TAPE.
  Easy Tape from Maynard Backup Systems is scheduled for future release.
  Contact Maynard for information.


  Colorado Jumbo

  For Colorado Jumbo tape drives connected to a diskette-drive controller, you
  must set up a DOS Startup session from a diskette image and run the tape
  backup program from it.  To do this, you need to refer to the topic "Starting
  DOS from an image file" in the Master Help Index.

  The Colorado Jumbo Tape program allows you to specify some hardware and
  software settings to be used when backing up files.  The CONCURRENT DISK/TAPE
  OPERATION option must be set to No.  To change the option, start the program
  and select the Utilities menu (F3); then select SOFTWARE SETUPS (F6).  Change
  the option to N.

  The Colorado company is developing an OS/2-specific version of their program.
  For more information, contact Colorado.

  IBM PS/2 MODEL 30-286 UPGRADES

  IBM PS/2 Model 30-286 upgrades to a 386 microprocessor are not supported.


  50 MHZ SYSTEMS

  There have been some intermittent problems using 50 MHz systems with AT-style
  bus computers with a mouse.  The mouse can get out of synchronization.  Input
  will function through the keyboard and the mouse, but to avoid possible
  problems, shut down the system and restart to resynchronize the mouse.


  LOGITECH 3-BUTTON MOUSE

  The Logitech 3-button bus mouse is supported as a 2-button mouse.  It is
  treated as a Microsoft 2-button bus mouse.

  A Logitech serial mouse with 3 buttons behaves as expected in DOS sessions.
  In a Presentation Manager session, however, there might be different and more
  limited functions assigned to the buttons.  There are no standards for the
  functions of 3-button mice.


  AOX SYSTEMS

  If your computer has an Aox** add-in microprocessor adapter card and you
  encounter problems either installing or starting up your OS/2 system, you can
  call the Aox Corporation and ask for the latest "flash-prom" code upgrade.


  PERSTORE

  PerStore drive controllers are not supported.


  INTERRUPT PROBLEMS ON AN ISA SYSTEM

  On an ISA system, having a shared interrupt-request line can cause problems.
  ISA systems have what are called edge triggered interrupts, whereas Micro
                                   ______________
  Channel and EISA systems use level sensitive interrupts.  Edge triggered
                               _______________
  interrupts can only be sensed for a very short period.  If a second interrupt
  arrives from another adapter while the first interrupt is still being
  processed, the second interrupt will be lost.  In your computer system, this
  situation can lead to various difficulties, such as printers that do not seem
  to print smoothly or reliably, or communications sessions where some
  characters are getting lost.



  9-8  Tips and Techniques









  However, with single-tasking systems such as DOS, the two adapters that are
  sharing the interrupt might never cause any real problems because they might
  never be in use at the same time.  However, OS/2 2.0 presents a different set
  of problems.  If you have multiple serial communications adapters, there is a
  greater probability that you might try to use two or more of them at the same
  time.  If some of them have previously been set up using shared interrupts,
  problems can occur that probably didn't happen in DOS.

  OS/2 2.0 can detect that an interrupt line is shared and will not allow
  simultaneous use.  Assume that COM1 and COM3 are sharing Interrupt Request
  line 4 (IRQ4).  If you try to use both COM ports at the same time, the OS/2
  operating system will not allow the second one to start.  A well-written OS/2
  communications program will recognize that the port cannot be opened and an
  error message will be displayed.  However, a DOS program is unprepared to
  respond to this unfamiliar situation.  It will probably suspend, waiting for
  the port that will not open.

  Another potential source of trouble is having multiple hardware adapters that
  are sharing the same I/O address.  The various hardware adapters in your
  computer must have their own addresses.  Consider what might happen, for
  example, if the commands that were meant for your printer were instead routed
  to your disk drive.

  The solution for all of these problems is to ensure that all your hardware
  adapters have their own unique I/O addresses and IRQ assignments.


  COMMUNICATION PORTS ACCESSED BY DOS APPLICATION PROGRAMS

  When COM_DIRECT_ACCESS is set to On, DOS programs use VCOM.SYS to directly
  access communication ports.  COM_DIRECT_ACCESS enables LapLink III, FastLynx,
  FSDUAT, AS/400 Asynch Router, MS Word to work in a DOS session.  However,
  because buffers in COM.SYS cannot be used, characters are sometimes lost, and
  some programs experience difficulties from the lack of buffering.  Therefore,
  on most DOS programs, it is a good idea to set COM_DIRECT_ACCESS to Off as
  its default setting.

  COM_SELECT enables a DOS session to select and use one communication port.
  Communication ports that are not selected are hidden from the DOS session.
  There are some DOS programs that take over every available communication
  port, such as LapLink Pro.  If LapLink Pro and another program that accesses
  a communication port are executed at the same time, it is necessary to set
  COM_SELECT to All as its default setting.


  COMMUNICATION PORT IS NOT RECOGNIZED OR DOES NOT WORK

  Most problems with Interrupt Request (IRQ) lines and I/O address settings
  occur on an AT bus (ISA) computer as a limitation of the hardware.  IRQ lines
  can be shared on a micro channel (MCA) computer provided the adapter card is
  MCA compatible and is configured with the Reference Diskette.

  The follow provides some solutions for your communications problems:



                                              Chapter 9.  Hardware Support  9-9









  o   Verify that all IRQ levels and I/O addresses are unique for every adapter
      card.  The normal problem is that communication adapters, such as
      internal modems, FAX machines, etc., use COM3 and IRQ4, which are already
      in use by COM1.  You MUST change the IRQ on the adapter card to one that
      is not in use.  Refer to the documentation that came with the adapter
      card.

  o   Verify that the correct parameters are being passed to the COM.SYS driver
      in the CONFIG.SYS file.  Refer to "Communication Ports Accessed by DOS
      Application Programs" on page 9-9.

  o   Obtain the latest OS/2 2.0 communication drivers.

  o   During boot, if the message "COMx not installed because Interrupt is
      already in use" appears, ensure there is no IRQ conflict with other
      device drivers or hardware.

  o   If the system (AT bus or MCA) boots without an error but the
      communication ports are not working, type the following at an OS/2
      command prompt:

           MODE COMx

      Where x is the problem communication port.  If a message appears
            _
      indicating the COMx port is not installed, check for IRQ conflicts.
                        _

      NOTE:  If the mouse is on a communication port, the message "SYS1620 COM
             port specified is not installed" appears.

  o   If the program is a DOS communication program, set DOS_SETTINGS to the
      following:

      COM_HOLD                 On

      COM_DIRECT_ACCESS        On or Off*

      COM_Select               Specified COMx*
                                            _

      DOS_DEVICE               X:\OS2\MDOS\COMMDD.SYS**

      HW_ROM_TO_RAM            On

      HW_TIMER                 On

      IDLE_SECONDS             60

      IDLE_SENSITIVITY         100

      *Requires the latest device drivers.  Refer to "Communication Ports
      Accessed by DOS Application Programs" on page 9-9.

      **The DOS_DEVICE (COMMDD.SYS device driver) might require more than one
      device driver depending on the program.  For example, Intel's
      SatisFAXtion requires a device driver loaded into each DOS session that


  9-10  Tips and Techniques









      uses an adapter.  The COMMDD.SYS device driver is usually required only
      for earlier DOS communication programs.  Do not use DOS_DEVICE for every
      DOS communication session; use it only if it resolves the problem.

  o   To provide a higher priority to all communication programs, edit the
      following in the CONFIG.SYS file:

           PRIORITY_DISK_IO:   NO
           MAXWAIT:                  1

  o   Some DOS programs open all the communication ports.  If this occurs, use
      the COM_SELECT DOS property (see "Communication Ports Accessed by DOS
      Application Programs" on page 9-9) in all DOS communication sessions.


  COM3 OR COM4 SUPPORT ON AN ISA SYSTEM

  The original ISA computer (the IBM Personal Computer AT) allowed for the
  definition of up to four serial communication ports.  However, there has
  never been any hardware architectural standard that defined the I/O port
  addresses or IRQ lines associated with communication ports 3 or 4.

  Over the years, a convention has developed that places the port addresses for
  COM3 and COM4 at 03E8 and 02E8 respectively.  This is a generally accepted
  convention, but not a standard.  Check the documentation and the settings of
  the adapters in your system to verify your hardware environment.

  After you have checked and set the I/O and IRQ values on your COM ports or
  internal modems, you must add this information to the communications
  device-driver (COM.SYS) statement in the CONFIG.SYS file.

  You might also need to tell your communications program where the COM ports
  are.  ProCom software, for example, has a configuration screen that enables
  you to specify these settings.  If the program, operating system, and
  hardware are not in agreement, then the program will not run.

  OS/2 COM ports do not need to be defined in sequence.  It is acceptable to
  have a COM4 without having a COM3.  DOS, however, might have difficulty if
  there is a gap in the port definition.  To avoid confusion for DOS, you can
  define COM ports that do not have any physical adapters attached in the
  COM.SYS statement.  These substitute definitions will serve as placeholders.
  COM1 and COM2 are assumed to have standard values and do not need to be
  explicitly set up unless you want to set some nonstandard values to
  accommodate your particular configuration.

  To enable COM3 or COM4 on an ISA system, place the following in the
  CONFIG.SYS file:

    DEVICE=X:\OS2\COM.SYS (n,a,i) (n,a,i)

  where:

  X    is the drive where OS/2 is installed.
  N    is the communication port that you are attempting to access.


                                             Chapter 9.  Hardware Support  9-11









  A    is the communication port I/O address (for example, 03E8 and 02E8).
  I    is the IRQ level, which is usually a jumper setting on the I/O adapter.

  For example, to specify that COM3 is at address 03E8 on IRQ5 and that COM4 is
  at address 02E8 on IRQ10, use the following statement (assuming that OS/2 is
  installed on drive C):

          DEVICE=C:\OS2\COM.SYS (3,03E8,5) (4,02E8,10)

  The I/O address and IRQ level should be noted in the documentation that came
  with your adapter.  Either or both might be fixed values or can be set to a
  range of values via jumpers or switches.  In some cases you might find that
  the values are fixed or that the range of settings available to you is
  insufficient to avoid the sharing conflict.  In that case, you must purchase
  a different, more versatile adapter or accept that you cannot use both
  adapters at the same time.


  SETTING THE INTERRUPT REQUEST (IRQ) LEVEL ON AN ISA SYSTEM

  The following information will help you determine what IRQ settings you can
  use for COM3 or COM4 port adapters to avoid shared interrupts.

  On an ISA machine there are a total of 15 IRQ levels available.  Many of
  these are already being used.  Most are already in use because they are the
  the standard settings for the more common devices.  These standard settings
  are as follows:

  IRQ LEVEL      DEVICE ASSOCIATED

  0              System Timer

  1              Keyboard

  2              Secondary Interrupt Controller  (see note)

  3              COM2 (Serial Communications Port 2)

  4              COM1 (Serial Communications Port 1)

  5              LPT2 (Parallel Port 2)

  6              Diskette

  7              LPT1 (Parallel Port 1)

  8              Real-time Clock

  9              open

  10             open

  11             open



  9-12  Tips and Techniques









  12             open

  13             Math Coprocessor

  14             Hard Disk

  15             open

  NOTE:  On the IBM-AT (ISA bus), the IRQ9 pin is identical with the IRQ2 pin
         on the original IBM-PC.  If you have an earlier, 8-bit adapter whose
         documentation states that it uses IRQ2, be aware that this will
         actually be interpreted as IRQ9 when plugged into the 16-bit ISA bus.

  The IRQ levels shown as "Open" have no established, standardized use.  When
  setting the IRQ values on your COM3 or COM4 ports, you are likely to find
  these levels available to use without conflict with some other adapter.
  Furthermore, if you don't have two parallel ports installed, IRQ5 might be
  usable for some other purpose, such as COM3 or COM4.  Be cautious about doing
  this because it might cause a problem later if you decide to install a second
  parallel port.  In addition, some other nonstandard device might already be
  using IRQ5.

  When trying to manage the IRQ levels of your various hardware adapters to
  avoid conflicts, you might find that your 8-bit adapters cause problems.
  Except for IRQ9, only 16-bit adapters are configurable to use IRQ levels
  higher than 7.  Notice that IRQ table shows that the low-numbered IRQ lines
  already have some standard function assigned.  It might be that your only
  alternative for avoiding some IRQ conflicts is to purchase a more versatile
  16-bit adapter.

  If you have nonstandard 8-bit adapters, be especially careful of interrupt
  conflicts.  For example, the SoundBlaster adapter is configured at the
  factory to use IRQ7.  IRQ7, however, is the standard assignment for LPT1, the
  first printer port.  This conflict might not be apparent with DOS because DOS
  printing typically does not use the interrupt line.  OS/2 2.0, however,
  requires it, and the hidden conflict can become the source of printing
  problems.  It is also fairly common to discover that the interrupt feature on
  your parallel-port adapter does not work.  In DOS, this might not have any
  effect.  In OS/2 2.0, however, your printer might be very erratic or not work
  at all.


  PARALLEL-PORT-ATTACHED DEVICE

  o   If you have a parallel device (for example, a tablet system, LAN adapter,
      or SCSI device) that does not work in a DOS session, it might be because
      interrupt IRQ7 is not reflected in the session.  Your device might
      attempt to use the parallel-port feature and is prevented from doing so.
      OS/2 developers are working on a solution for this limitation.

  o   Some security devices (known as dongles) attached to a parallel port do
                                      _______
      not work properly with OS/2 2.0.  The DOS program that uses the device
      can start from one DOS session only.  An error message appears when you
      try to start additional copies of the program.  You can press


                                             Chapter 9.  Hardware Support  9-13









      Ctrl+Alt+Print Screen to release access to the parallel-port program
      prior to starting the second copy of the DOS program.

  o   Make sure you are using cables that are properly shielded and wired.
      (For more information, refer to "Unable to Print" on page 7-7.)


  FAX ADAPTERS

  When certain fax adapters are operating as ordinary modems, they might
  operate correctly yet fail to work correctly as a fax device in a DOS
  session.  The probable cause of the trouble is the VCOM.SYS device driver.
  VCOM.SYS might be introducing timing distortions into those hardware commands
  that are used to control the fax device but are not a part of normal
  asynchronous communications.

  Because there are no standards established for fax controls, it might be that
  the only solution is to acquire an OS/2-based fax device driver and program.
  Your fax adapter manufacturer might have information on sources and
  availability of OS/2-based program.

  Without purchasing new software, you can try removing the VCOM.SYS statement
  from your CONFIG.SYS file.  This might allow your fax adapter to work
  properly but might have other undesirable side effects.  One of the functions
  of VCOM.SYS is to provide a performance assist.  Without VCOM.SYS, you might
  have to use a reduced baud rate.  Also, some programs, such as Prodigy, will
  not run without it.  Therefore, while removing VCOM.SYS is all right in some
  instances, it might not be the right action for you.

  If you have an ISA bus system, you might consider making changes to the fax
  adapter so that only part of your system detects it.  Then, place all
  operation into a single DOS session.  This is possible on an ISA system if
  you can set up your fax adapter as COM3 or COM4.  Since there are no
  standards for COM3 or COM4 on an ISA system, OS/2 2.0 will not recognize the
  adapter unless it is defined for the system in the CONFIG.SYS file (See the
  section "COM3 or COM4 Support on an ISA System" found earlier in this
  chapter).

  To set up this configuration, set the hardware switches on the fax adapter to
  indicate either COM3 or COM4.  Use a setting that is available and that does
  not conflict with other adapters.  Leave VCOM.SYS in your CONFIG.SYS
  definition but do not define the fax adapter settings to the COM.SYS device
  driver.  When OS/2 2.0 starts up, it will not recognize the fax adapter, but
  the normal communications ports will still get the benefit of having VCOM.SYS
  available.

  Next, set up a DOS session so that it loads the DOS programs that you use for
  faxing and also the DOS device driver used to control the fax adapter if it
  came with a special driver.  Check your documentation to be sure.  This
  single DOS session should now be able to operate your fax adapter normally.

  In some cases, this still might not work.  If the DOS program treats the
  adapter as a COM port instead of directly accessing the hardware, then DOS
  will not recognize the adapter either.  The only problem with this


  9-14  Tips and Techniques









  configuration is that this single DOS session controls the adapter.  Other
  DOS or OS/2 sessions will not be able to access it at all.

  IBM is working on a fix to alleviate this problem, but the best solution is
  to use OS/2-specific device drivers and programs, especially where
  performance is critical.


  PS/2 EXTERNAL 5.25-INCH 1.2MB DISKETTE DRIVE

  If you cannot get the external 5.25-inch 1.2MB diskette drive to work on a
  PS/2 computer, install the device driver that comes with the drive into the
  OS2 directory in the startup partition.  The device driver is called
  EXT5DD.SYS.  Change your CONFIG.SYS file statement to read \OS2\EXT5DD.SYS
  instead of \OS2\EXTDSKDD.SYS.


  IBM PS/2 MODEL 90 OR 95

  If you are experiencing problems with your Model 90 or 95, ensure your system
  is at the latest engineering change (EC) level.  Your IBM service
  representative can assist you.

  If your Model 90 or 95 is a 33 MHz system and you are having intermittent
  difficulty identifying memory parity errors such as TRAP 0002, forcing you to
  restart your system, then ECA053 might apply.  If your microprocessor card
  has part number 84F9356, contact your IBM representative to assist you with a
  replacement.

  If your Model 90 is experiencing intermittent memory errors, ECA084 might
  apply if the part number of your memory riser card is N33F4905 or 84F9356.
  Again, your IBM representative can assist you with a replacement.

  For both Model 90 and 95 computers, you must ensure that you have matched
  pairs of single inline memory modules.  This means that each pair of single
  inline memory modules, as described in your technical reference manual, must
  be matched in memory size and speed.  Mixing these modules can cause some
  computers to report memory errors.


  FORMATTING DISKETTES
  ____________________

  If you have a non Micro Channel system with a 5.25-inch drive, and its
  3.5-inch drives all support media sense, your 5.25-inch drive will format
  diskettes at 720MB.  Previously formatted 1.2MB diskettes will read and write
  correctly.  A fix for this problem can be obtained from the electronic
  bulletin board described in Chapter 2 "Service and Support Information."
