Tech Bulletin: Using the Disk Interface Board (SCSI Card)
NOVELL TECHNICAL BULLETIN
TITLE: Using the Disk Interface Board (SCSI Card)
DOCUMENT ID: TB.P.150
DATE: 9/12/86
PRODUCT:
PRODUCT VERSION: Novell Disk Interface Board
SUPERSEDES: NA
SYMPTOM: NA
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.
