v 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: v Either level of memory testing can be performed on all memory or a single RIMM socket. v RIMM memory requires that all memory slots be filled, either with a RIMM or a continuity module (C-RIMM). Alert-On LAN™ test The Alert On LAN test does the following: v Determines if Alert On LAN is supported on the system. v Checks the revision ID register. v Verifies the EEPROM checksum. v Validates that a software alert can be sent. Asset ID™ test The Asset ID test does the following: v Determines if Asset ID is supported on the system. v Verifies the EEPROM areas. v Performs an antenna detection test. Test results Diagnostics test results will produce the following error code format: Function Code Failure Type DeviceID Date ChkDigits Text v Function Code: Represents the feature or function within the PC. v Failure Type: Represents the type of error encountered. v 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. v Date: Contains the date on which the diagnostic test was run. The date is retrieved from CMOS and displayed using the YYYYMMDD format. v ChkDigits: Contains a 2-digit check-digit value to ensure the following: - Diagnostics were run on the specified date. - Diagnostics were run on the specified IBM computer. - The diagnostic error code is recorded correctly. v Text: Description of the error. 14 Hardware Maintenance Manual
