vi Hardware Maintenance Manual
This general checkout procedure is for Types 2254, 2256, 2257, 6336, 6337, 6339, 6341, 6342, 6346, 6347, and 6348 computers.
Attention:
The drives in the computer you are servicing might have been rearranged or the drive startup sequence changed. Be extremely careful during write operations such as copying, saving or formatting. Data or programs can be overwritten if you select an incorrect drive.
Diagnostic error messages appear when a test program finds a problem with a hardware option. For the test programs to properly determine if a test Passed, Failed or Aborted, the test programs check the error-return code at test completion. See “Diagnostics” on page 12.
General error messages appear if a problem or conflict is found by an application program, the operating system, or both. For an explanation of these messages, refer to the information supplied with that software package.
Notes:
vTypes 2254, 2256, 2257, 6336, 6337, 6339, 6341, 6342, 6346, 6347, and 6348 computers default to come up quiet (no beep and no memory count and checkpoint code display) when no errors are detected by POST.
vTo enable beep and memory count and checkpoint code display when a successful POST occurs, do the following:
1.Select Start Options in the Configuration/Setup Utility program (see “Setup Utility program” on page 10).
2.Set Power-On Self-Test to Enhanced.
vBefore replacing any FRUs, ensure that the latest level of BIOS is installed on the system. A down-level BIOS might cause false errors and unnecessary replacement of the system board. For more information on how to determine and obtain the latest level BIOS, see “BIOS levels” on page 199.
vIf multiple error codes are displayed, diagnose the first error code displayed.
vIf the computer hangs with a POST error, go to ″Symptom-to-FRU Index″ on page 69.
vIf the computer hangs and no error is displayed, go to “Undetermined problems” on page 109.
vIf an installed device is not recognized by the diagnostics program, that device might be defective.
001

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.
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.
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″.

The quick memory test will take about 20 seconds per MB of memory and will detect solid (stuck) memory failures only.
Notes:
vEither level of memory testing can be performed on all memory or a single RIMM socket.
vRIMM memory requires that all memory slots be filled, either with a RIMM or a continuity module (C-RIMM).
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.
The Asset ID test does the following:
vDetermines if Asset ID is supported on the system.

Use the Hard File Smart Test when the system management tool has detected a hard file SMART alert.
The Smart test does the following:
vInterrogates IDE devices for support of the SMART instruction set.
vIssues a ENABLE SMART command to make sure SMART functionality is active.
vChecks the SMART RETURN STATUS command to determine if any thresholds have been exceeded.
If thresholds have been exceeded, an error message is shown, and the test fails. If no SMART is supported by the drive, the test returns with ″N/A″.
The Diagnostics program offers two hard drive format utilities:
vQuick Erase Hard Drive
vFull Erase Hard Drive
The Quick Erase Hard Drive provides a DOS utility that performs the following steps.
vDestroys the Master Boot Record (MBR) on the hard drive.
vDestroys all copies of the FAT Table on all partitions (both the master and backup).
vDestroys the partition table.
vProvides messages that warn the user that this is a non-recoverable process.
Chapter 3. Diagnostics 15
The Full Erase Hard Drive provides a DOS utility that performs the following steps.
vPerforms all the steps in Quick Erase.
vProvides a DOS utility that writes random data to all sectors of the hard drive.
vProvide an estimate of time to completion along with a visual representation of completion status.
vProvides messages that warn the user about non-recoverable process.
Important: Make sure that all data is backed up before using the Quick or Full Erase functions.
To select the Quick Erase or Full Erase Hard Drive utility, use the following procedure.
1.Select the UTILITY option on the toolbar and press Enter.
