This document is divided into 6 Sections Section 1 OS/2 files on this disk Section 2 Installation of OS/2 onto a SCSI disk Section 3 Adding a QLogic Adapter to an existing system Section 4 Removable Devices Section 5 Command Line Parameters Section 6 Troubleshooting Section 1 OS/2 files on this disk ---------------------------------- The following files are on this disk for supporting OS/2: \OS2\QL12.DDP Device driver profile script required for the OS/2 Device Driver Install utility \OS2\QL12OS2.ADD OS/2 ADD driver for QLogic PCI QLA12xx SCSI adapters \OS2\README.TXT This file Section 2 Installation of OS/2 onto a SCSI disk ------------------------------------------------ To initially install OS/2 on a SCSI disk attached to the QLogic adapter or to install OS/2 from a CD-ROM player attached to the QLogic adapter: Installing OS/2 Version 2.1: 1. Make a copy of the IBM OS/2 Diskette 1 (use diskcopy command) 2. Copy the QL10OS2.ADD file from the \OS2 directory on the QLogic driver diskette onto the root directory on the copy of the OS/2 Diskette 1. 3. Edit the CONFIG.SYS file located on the copy of OS/2 Diskette 1, add the following statement to the end of the file: BASEDEV=QL12OS2.ADD 4. Start the installation by inserting the IBM OS/2 Installation Diskette into drive A and restarting the system, use the modified copy of Diskette 1 when prompted to insert Diskette 1. Installing OS/2 Warp Version 3 from CD-ROM: 1. Make a copy of the IBM OS/2 Warp Diskette 1 (use diskcopy command). 2. To make room for the QLogic driver, delete the following files from the copy of Diskette 1: For an ISA/EISA (non-Micro Channel) computer, delete: IBM2*.* For a Micro Channel computer, delete: IBM1*.* 3. Copy the QL12OS2.ADD file from the \OS2 directory on the QLogic driver diskette onto the root directory on the copy of the OS/2 Diskette 1. 4. Edit the CONFIG.SYS file located on the copy of OS/2 Diskette 1: a. Insert the letters REM before any lines in the CONFIG.SYS that refer to the files deleted in step 2 above. b. Add the following statement to the end of the file: BASEDEV=QL12OS2.ADD 5. Start the installation by inserting the IBM OS/2 Installation Diskette into drive A and restarting the system, use the modified copy of Diskette 1 when prompted to insert Diskette 1. Installing OS/2 Warp Version 3 from diskettes: 1. Start the installation by inserting the IBM OS/2 Installation Diskette into drive A and restarting the system, insert other diskettes as requested 2. During the installation from diskette, select "Advanced Installation". 3. When the System Configuration window is displayed, select the CD-ROM Device Support icon and then select the type of CD-ROM device to be supported. 4. After completing the OS/2 installation from diskettes, follow the procedure below to install the QLogic ADD driver using the Device Driver Install utility. Section 3 Adding a QLogic Adapter to an existing system -------------------------------------------------------- To install the QLogic ADD driver on a previously installed OS/2 system perform the following steps: 1. Boot up OS/2 system. 2. Insert QLogic SCSI driver diskette into drive A (or B). 3. Select "System Setup" from OS/2 System program group. 4. Select "Device Driver Install" from the System Setup group. 5. Change source directory to A:\OS2 (or B:\OS2). 6. Select "Install" 7. Select the "QLogic PCI SCSI ADD Driver" followed by "OK". The driver will be copied to your boot disk and your CONFIG.SYS file will be updated. 8. You must reboot your system after installing the driver. Section 4 Removable Devices ----------------------------- OS/2 currently does not support removable SCSI disk devices. The QLogic ADD driver provides limited support for these devices by treating them like a fixed disk device. The disk media must be inserted when booting OS/2, and the system must be rebooted when changing the disk media. To enable removable disk support, add the /!R parameter to the BASEDEV= command in your CONFIG.SYS file as follows: BASEDEV=QL12OS2.ADD /!R Section 5 Command Line Parameters ---------------------------------- The following command line parameters are supported by the QLogic ADD driver: (add to end of BASEDEV=QL12OS2.ADD line in config.sys file). /A:d Specifies which adapter (0-2) that following command line parameters apply to. /I Ignore the specified adapter (must follow "/A:d" parameter). /DM /!DM Enable/disable DASD manager support for specified adapter and/or devices (add ":d,d,d" to specify list of SCSI IDs or ":(d,d),(d,d),(d,d)" to specify ID,LUN pairs). Default is enabled. /SM /!SM Enable/disable SCSI manager support for specified adapter and/or devices (add ":d,d,d" to specify list of SCSI IDs or ":(d,d),(d,d),(d,d)" to specify ID,LUN pairs). Default is enabled. /!R Report removable disk devices to OS/2 as fixed disks. By default removable disks will be reported as removable. /SR /!SR Enable/disable SCSI bus reset during boot on specified adapter. Default is enabled. Do not disable the SCSI bus reset if synchronous negotiation is enabled on any device. /ET /!ET Enable/disable embedded target support for specified adapter. Default is enabled (all 8 LUNs supported). Specify /!ET for supporting LUN 0 only. /V Enable verbose mode (display configuration data during boot). Default is disabled. /RA Reorder adapters. This parameter is used to reverse the order in which the QLogic adapters are configured. This parameter is required on some systems with AMI BIOS and more than one QLogic adapter. Section 6 Troubleshooting -------------------------- When doing an initial installation of OS/2 using the QLogic adapter, OS/2 mistakenly places the command for loading the QLogic ADD driver at the beginning of the CONFIG.SYS file. This creates a problem if your system configuration includes both an IDE fixed disk (boot device) and a SCSI fixed disk device. When booting on the IDE disk, the ADD driver for the IDE disk (IBM1S506.ADD) must be loaded before the ADD driver for the SCSI disk. To get around this problem, remove the SCSI disk from the system while completing the installation onto the IDE disk. Then, edit CONFIG.SYS file and move the command for loading the QLogic driver from the beginning of the file to the end of the file. Finally, reinstall the SCSI disk.
