Title: Using the Disk Interface Board (SCSI Card) as a keycard.

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-
  ts3.  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-t, 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.
