The information below was kindly provided to me by SCO tech support
when I was getting my system up and running with the wd 7000 scsi
adapter:

:>Jumper information for the WD7000 SCSI host adapters.

:>KEYWORDS:   wd7000 scsi configure jumper settings address irq dma 

:>RELEASE:    SCO UNIX System V/386 Release 3.2 Operating System Version 2.0 

:>            Currently, the WD7000 is supported only on the above release
:>	    of the operating system.

:>PROBLEM:    What are the meanings of the jumper settings for the
:>	    WD7000 SCSI host adapter including: base address, memory
:>	    address, interrupt and dma?

:>            What are the settings required for the WD-7000 host adapter
:>            to work with SCO UNIX 3.2 Version 2.

:>SOLUTION:   Use the following information:

:>            To configure the WD-7000 to work with SCO UNIX 3.2 version 2,
:>            set the:

:>            IO Address to:.... : 350h 
:>            IRQ (Interrupt) to :  12
:>            DMA .............. :   6

:>            The following information will show you how to jumper the
:>            WD-7000 for the require settings, as well as other options.

:>            Jumper W3 = IO Address,  Jumper W2 = DMA (Pins 1 - 12)
:>            Jumper W1 = IRQ,         Jumper W4 = ROM Address
:>            Jumper W2 = IRQ (Pins 13-22)

:>            NOTE: PIN 1 IS ON THE LEFT HAND SIDE WITH THE EDGE
:>                  CONNECTOR TOWARD YOU.

:>ROM ADDRESS:  The address jumper is W4, in 4 banks of 2 pins.

:>PIN -->     13 14 15 16              
:>            [:][:] : [:] C800h  [:][:][:] : D000h  [:][:] :  : D800h

:>             : [:] : [:] CA00h   : [:][:] : D200h   : [:] :  : DA00h

:>            [:] :  : [:] CC00h  [:] : [:] : DA00h  [:] :  :  : DC00h

:>             :  :  : [:] CE00h*  :  : [:] : D600h   

:>             * Default Factory Setting

:>IO ADDRESS: The IO Address jumper is W3, in 5 banks of 2 pins.

:>PIN -->   9  7  5  3  1
:>         [:][:] : [:][:] 320h*   :  :  :  :  :  3f8h [:][:] :  :  : 3E0h

:>          : [:][:] :  :  3C8h   [:] :  : [:] :  3B0h  :  : [:][:] : 398h

:>         [:][:][:][:] :  380h   [:] :  :  : [:] 370h  :  :  : [:][:] 338h

:>         [:] : [:][:][:] 310h   [:][:][:][:][:] 300h [:] : [:] : [:] 350h 

:>INTERRUPT: A combination of W1 and W2 are used to configure the IRQ.
:>           IRQ channels available are 3-5, 7, 9-12 and 14-15; IRQ 3 is
:>           shown as the standard default.

:>PIN -->      1   3  5  7  9 13 15 17 19 21 
:>            [:]  :  :  :  :  :  :  :  :  :   
:>IRQ -->      3   4  5  7  9 15 14 12 11 10

:>DMA CHANNELS:  Available DMA Channels are 5,6 and 7.  The default is 6.
:>               DMA must use the same channels for Request and Acknowledge.
:>               Jumper W2 (Pins 1-12) are used.

:>PIN -->     1   3   5  7   9  11 
:>            :  [:]  :  :  [:]  :
:>            D   D   D  D   D   D

:>                       7   6   5

:>OTHER JUMPERS:  

:>FLOPPY CONTROL:  Remove Jumpers W6 and W9 to enable floppy controller.

:>DUAL SPEED FLOPPY SPINDLE:  Jumper W7 when installed enables a dual
:>                            speed 300/360 RPM spindle.

:>FLOPPY WRITE PRECOMP SELECT:  When Jumper W8 is installed, the write precomp
:>                              is set for 187 NS (for a 1.2Mb floppy).  When 
:>			      removed, its value is 125 NS (360 Kb)

:>TERMINATION POWER: Jumper W5 when installed supplies power to resistor
:>                   packs Z1 and Z2.  All resistor packs between the two
:>                   ends of the SCSI cable must be disabled or removed.
:>                   In general, W5 should be installed.
