Module test menu/hardware configuration report
Depending on the diagnostics version level you are using, the installed devices in the
computer are verified in one of two ways.
1. At the start of the diagnostic tests, the Module Test Menu is displayed. Normally,
all installed devices in the computer are highlighted on the menu.
2. At the start of the diagnostic tests, the main menu appears. From this menu, select
System Info
, then select Hardware Configuration from the next menu. Normally,
all installed devices in the computer are highlighted on this report.
If an installed device is not recognized by the diagnostics program, then review the
following:
• The diagnostic code for the device is not in the Diagnostics program. Run the
diagnostics provided with that device.
• The missing device is defective or it requires an additional diskette or service
manual.
• An unrecognizable device is installed.
• A defective device is causing another device not to be recognized.
• The SCSI controller failed (on the system board or SCSI adapter).
• Use the procedure in “Undetermined problems” on page 81 to find the problem.
If a device is missing from the list, replace it. If this does not correct the problem, use
the procedure in “Undetermined problems” on page 81.
