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 340-343. 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.
