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 Refer-
ence Manual for further information on these parameters.
NOTE
Step 6 requires execution of low level formatting. Use of the
IBM Advanced Diagnostic (or similar program for IBM-
compatibles) 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.
