	      Notes on Configuring the DEC FDDIcontroller/EISA
-----------------------------------------------------------------------------

     There are three EISA configuration files provided for the
     controllers: !DEC3001.CFG, !DEC3002.CFG, and !DEC3003.CFG.
     The file you use to configure the system depends upon the
     part number of the controller you are installing.  The
     controller's part number is marked on a label attached to
     the controller.
     
     Refer to the following listing to determine which EISA
     configuration file you should use:

!DEC3001.CFG - The EISA Configuration Utility configuration file for
	       DEC FDDIcontroller/EISA Part # 54-21497-0X
!DEC3002.CFG - The EISA Configuration Utility configuration file for
	       DEC FDDIcontroller/EISA Part # 54-21503-0X and 54-24239-0X
!DEC3003.CFG - The EISA Configuration Utility configuration file for
	       DEC FDDIcontroller/EISA Part # 54-24889-0X

The following rules may prove useful in resolving EISA configuration 
process problems:

- Make a working copy of the configuration disk that came with your
  system.  Most PC vendors advise you to do this.  Because the EISA
  configuration process writes configuration data to the disk, store
  an original copy of your disk, in case the working copy becomes
  corrupted.

- Locate where all of the configuration files are on your working disk,
  and use DOS to copy the DEC FDDIcontroller/EISA configuration files
  to that location.  Most EISA configuration utilities provide some means
  of copying configuration files from the distribution disk to the
  configuration disk.  The best way to do this is by booting your
  system into DOS BEFORE installing the controller.  Then, use DOS to copy
  the configuration file to the configuration disk.  This is not only
  faster, but also lessens the possibility that your configuration utility
  will be unable to locate the configuration file on the distribution disk.

- If, after you install the controller successfully, and you reset the PC,
  the screen is blank or the once-working disk controller card no longer
  installs successfully, you need to check for ISA devices in your
  configuration.
  
  The EISA configuration utility reads your current system configuration 
  and verifies that there are no resource conflicts.  When conflicts arise, 
  the utility either modifies the settings of one or more devices to remove 
  the conflict, or instructs the user to remove the conflict.  Often, a
  conflict occurs with the presence of an ISA device in the configuration.      
  
  The EISA configuration utility assumes that there are no ISA devices 
  installed in the computer.  ISA devices are not included in the EISA 
  configuration process.  It is possible to write ISA configuration
  files for the EISA configuration process, but unlike EISA devices which
  have their hardware settings modified through the utility, ISA devices
  almost always come with jumpers and require the user to turn off the
  computer and physically adjust the jumper settings.  This manual user
  intervention means that ISA configuration files might not reflect the
  current ISA jumper settings.  Consequently, the EISA configuration
  utility may not recognize a conflict with an ISA device when one
  exists.  When ISA devices are present in your EISA computer, you must
  determine the resources used by any of your ISA options and must
  reconfigure the DEC FDDIcontroller/EISA option accordingly.

Specific Configuration Options:

- The EISA configuration files allow the controller to be configured for
  shared or non-shared interrupts.  Shared interrupts may be used with the
  NetWare 3/4 ODI server, SCO UNIX, Windows 95, and Windows NT drivers only.  
  All other drivers require that the controller be configured for non-shared 
  interrupts.

- The EISA configuration files allow the controller to be configured for
  1K or 0K memory.  The 0K option may be used with all drivers except the
  SCO UNIX LLI driver which requires at least the 1K memory option.

- Previous releases of the EISA configuration files allowed the controller
  to be configured for 32K or 64K memory.  Since the 32K and 64K memory
  options provide no practical advantage over other smaller memory options,
  they have been removed from the current EISA configuration files.  For the
  sake of backwards compatibility, however, the device drivers will continue
  to support the use of 32K and 64K memory options.

  The configuration options are summarized in the following table:

			 Memory Options     Shared Ints/    Maximum NICs
