IBM PC Enhanced Memory Diagnostics

The IBM PC Enhanced Memory Diagnostics provide the capability to identify a
particular memory module (SIMM/DIMM) which fails during testing. See "System
Board Layout" on page H-5 to locate the memory sockets.
Follow the steps below to locate the IBM PC Enhanced Memory Diagnostics test
options.
Notes:
Alert on LAN Test
The Alert on Lan test performs the following tasks:
Asset ID Test
The Asset ID test performs the following tasks:
1. Select the DIAGNOSTICS option on the toolbar and press Enter.
2. Highlight either the Memory Test-Full or Memory Test-Quick option and press
Enter.
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.
Memory Test-Quick
The quick memory test will take about 20 seconds per MB of memory and will
detect solid (stuck) memory failures only.
1. Either level of memory testing can be performed on all memory or a single
SIMM/DIMM socket.
2. Only sockets containing a SIMM or DIMM can be selected for testing.
Unpopulated sockets are noted by an elipsis (.........) beside the test description.
Determines if Alert on LAN is supported on the system.
Checks the revision ID register.
Verifies the EEPROM checksum.
Validates that a software alert can be sent.
Determines if the Asset ID feature is supported on the system.
Verifies the EEPROM areas.
Performs an antenna detection test.
