ISSUE/PROBLEM

     It is not possible to use Novell's Disk Coprocessor Board (DCB) as a
     keycard.

     The Disk Interface Board (DIB) may be used in place of a keycard for all
     86 and 286 systems.  Be sure to perform the following steps.

     1.   Set the switches in both banks to either the "ON" or the "closed"
          position.  (Some banks are labeled on/off and others are labeled
          closed/open.) This tells the board that no disk drives are attached.
          In this arrangement the board will still use IRQ-2, DMA-1, and I/O
          Ports 340-343.  The board also has an EPROM socket that decodes at
          D000:0.

     2.   The interrupt and DMA channel may be changed by setting the switches
          in banks S1.5.  Select a configuration that will NOT conflict with
          any other boards or devices that you currently have installed in
          your machine.  The following is a list of possible settings:

          IRQ-2, DMA-1, all switches set to "ON" position
          IRQ-3, DMA-1, Switch 3 "OFF," all others "ON"
          IRQ-5, DMA-1, Switches 2 and 3 "OFF," all others "ON"
          IRQ-2, DMA-3, Switch 1 "OFF," all others "ON"
          IRQ-3, DMA-3, Switches 1 and 3 "OFF," all others "ON"
          IRQ-5, DMA-3, Switches 1, 2 and 3 "OFF," all others "ON"
          IRQ-2, No DMA, Switch 2 "OFF," all others "ON"
          IRQ-3, No DMA, Switches 1 and 2 "OFF," all others "ON"

     3.   If you have the "Enhanced SCSI Adapter" which has been made since
          June 1985, you may also disable the EPROM decode.  This is done by
          setting switches 6, 7 and 8 in bank S1.5 to the "ON" position.
