IBM PC Enhanced Memory Diagnostics

The IBM PC Enhanced Memory Diagnostics provide the capability to identify a particular memory module (SIMM or DIMM) which fails during testing. Use the System Board Layout section to reference the memory sockets, or select F1 twice to load the Online Manual and select Chapter 11, ″SIMM/DIMM/RIMM Locator″.

Follow the steps below to locate the IBM PC Enhanced Memory Diagnostics test 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.Memory 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.

4.Memory Test-Quick

The quick memory test will take about 20 seconds per MB of memory and will detect solid (stuck) memory failures only.

Notes:

1.Either level of memory testing can be performed on all memory or a single SIMM or DIMM socket.

2.Only sockets containing a SIMM or DIMM can be selected for testing. Unpopulated sockets are noted by ........ beside the test description.

Alert-On LAN test

The Alert On LAN test does the following:

vDetermines if Alert On LAN is supported on the system.

vChecks the revision ID register.

vVerifies the EEPROM checksum.

vValidates that a software alert can be sent.

Asset ID test

The Asset ID test does the following:

vDetermines if Asset ID is supported on the system.

vVerifies the EEPROM areas.

vPerforms an antenna detection test.

Test results

IBM PC Enhanced Diagnostic test results will produce the following error code format:
