Module test menu and 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:
v The diagnostic code for the device is not in the Enhanced Diagnostics
utility. Run the diagnostics provided with that device.
v The missing device is defective or it requires an additional diskette or
service manual.
v An unrecognizable device is installed.
v A defective device is causing another device not to be recognized.
v The SCSI controller failed (on the system board or SCSI adapter).
v Use the procedure in “Undetermined problems” on page 90 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 90.
