14 IBM : Hardware Maintenance Manual
• Memory Test-Quick
The quick memory test will take about 20 seconds per MB of memory and
will detect solid (stuck) memory failures only.
Alert-On LAN™ test
The Alert On LAN test does the following:
• 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.
Asset ID™ test
The Asset ID test does the following:
• Determines if Asset ID is supported on the system.
• Verifies the EEPROM areas.
• Performs an antenna detection test.
Test results
Diagnostics test results will produce the following error code format:
• Function Code:
Represents the feature or function within the PC.
• Failure Type:
Represents the type of error encountered.
• DeviceID:
Contains the component's unit-ID which corresponds to either a fixed disk drive,
removable media drive, serial or parallel port, processor, specific RIMM, or a
device on the PCI bus.
• Date:
Contains the date on which the diagnostic test was run. The date is retrieved from
CMOS and displayed using the YYYYMMDD format.
• ChkDigits:
Contains a 2-digit check-digit value to ensure the following:
— Diagnostics were run on the specified date.
Notes:
• Either level of memory testing can be performed on all memory or a single RIMM socket.
• RIMM memory requires that all memory slots be filled, either with a RIMM or a
continuity module (C-RIMM).
