PCI Co-Processor Adapter Diagnostics Test
Notes:
1. You can test the PCI co-processor adapter with or without the
37-pin wrap plug (shown in “Service Parts” on page 4-22). The
wrap plug lets you test the electrical interfaces.
2. If at any time during diagnostics testing, you get a screen with
non-decipherable data, see the steps under “Blank Screen,
Blinking Cursor, or Non-Decipherable Data” on page 4-5.
Otherwise, follow the step-by-step procedures.
3. If you receive an error message during any of the tests, record
the error message and have the system unit serviced, unless
otherwise stated.
During diagnostics testing, instructions appear on the screen. Follow
the instructions as they appear.
