A selected test is marked by >>. Pressing the space bar again de-selects a test and removes the chevron.

4.Repeat steps 2 and 3 above to select all desired tests.

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:

vThe diagnostic code for the device is not in the Diagnostics program. Run the diagnostics provided with that device.

vThe missing device is defective or it requires an additional diskette or service manual.

vAn unrecognizable device is installed.

vA defective device is causing another device not to be recognized.

vThe SCSI controller failed (on the system board or SCSI adapter).

vUse the procedure in “Undetermined problems” on page 109 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 109.

Memory Diagnostic tests

The Memory Diagnostics provide the capability to identify a particular RIMM memory module which fails during testing. Use the System Board Layout section to reference the memory sockets, or select F1 twice to load the Diagnostics online manual and select SIMM/DIMM/RIMM Locator.

Follow the steps below to locate the Memory Diagnostic tests options.

1.Select the DIAGNOSTICS option on the toolbar and press Enter.

2.Highlight either the Memory Test-Fullor Memory Test-Quickoption and press Enter.

3.

vMemory Test-Full

The full memory test will take about 80 seconds per MB of memory and will detect marginal, intermittent, and solid (stuck) memory failures.
