DOCUMENT SCOPE
This document describes the hardware and software installation of the following boards:
WD1002-WAH Winchester Disk Controller
WDl002-WA2 Winchester/Floppy Disk Controller
WDl003-WAH Winchester Disk Controller
WDl003-WA2 Winchester/Floppy Disk Controller
NOTE
These controllers are designed for use in IBM Personal
computer ATs or other AT-compatible computers with a 16bit data bus.
The use of the term controller refers to all boards described
within this document. When a specific reference is made to a
particular board. the appropriate WD part number is used.
HARDWARE INSTALLATION
This section briefly describes installation of your hardware. If
the disk drive(s) is(are) being installed internally, it is best to
locate the controller in the nearest available expansion slot to
the drive.
CAUTION
Handle the controller board by the ends of the
board. Some of the chips are static sensitive and
damage may occur If the board is incorrectly
handled.
NOTE
Only verify the jumper settings in Step 1. Modification of the
standard factory jumper settings on any equipment described
in this document is rarely necessary. Modify jumpers only
under the direction of a qualified individual; i.e., your dealer.
1.
Verify controller jumper settings. Refer to pages 3
through 6 for jumper setting information.
2.
Verify termination on last drive. Verify proper setting of
drive select switches on drive; i.e., set the drive select
switches for drive select 1 or 2. Refer to your system
owner's manual for information about proper drive
termination and select switches.
3
. Remove the blank expansion slot bracket. Put the bracket
away and save it for possible future use. The screw will
be used to hold the new controller board in place.

4.
Attach 34-pin control connector pin 1 to J1 (J5 for
WDl002-WA2 or WDl003-WA2) pin 1. Pin 1 is in the
lower left hand corner of J1. Pin 1 is in the upper left
hand corner of J5.
5.
Connect control cable to drive.
6.
Attach 20-pin data connector to J2 (drive C or 1) for the
WD1002-WAH or WD1003-WAH (J4 for WD1002WA2 or WD1003-WA2).
7.
Attach 20-pin data connector to J3 (Drive D or 2).
8.
Connect data cables to drives.
9.
Attach 34-pin floppy cable connector to J1. Connect
cable to floppy drive. This step applies to WD1002-WA2
and WDl003-WA2 users only.
10.
Attach Winchester activity LED connector to J6 for all
controllers except the WDl002-WAH. The reference
designator for the Winchester activity LED connector on
the WD1002-WAH is J4.
11.
Install the controller board into the expansion slot. Make
sure that the board is seated properly by pressing down
on both ends of the board. Secure the board with the
bracket screw.
12.
Remove or disable any other floppy controller in your

SOFTWARE INSTALLATION
This section contains instructions for preparing (low level
format, etc.) your operating system to recognize the Western
Digital controller.
1
. Insert your system Diagnostic Diskette (or equivalent).
2.
Turn on the power
3.
Boot diagnostic and select setup option.
4
. Set clock etc.
CAUTION
Avoid system damage by consulting your
Technical Reference manual to ensure that your
drive type is supported by your host BIOS drive
tables. Not all AT-compatibles share the same
drive tables as IBM
5.
Select proper drive type. Consult your Technical Reference Manual for further information on these parameters.
Step 6 requires execution of low level formatting. Use of the
IBM Advanced Diagnostic (or similar program for IBMcompatibles) is necessary since these controllers contain no
on-board Basic Input/Output System (BIOS) ROM.
6.
Insert your Advanced Diagnostic diskette and execute
low level Format. Follow instructions in your reference
manual.
7.
Insert System Diagnostic Diskette (or equivalent) after
the system finishes the low level format.
8.
Load and execute the FDISK and FORMAT programs.
Follow instructions in your reference manual.
