General checkout
This general checkout procedure is for IntelliStation Type
6868/6878 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 “IBM PC Enhanced Diagnostics” on
page 322.
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
1. Before replacing any FRUs, ensure 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 341.
2. If multiple error codes are displayed, diagnose
the first error code displayed.
3. If the computer hangs with a POST error, go to
“Symptom-to-FRU index” on page 360.
4. If the computer hangs and no error is displayed,
go to “Undetermined problem” on page 382.
5. If an installed device is not recognized by the
diagnostics program, that device might be
defective.
The power-on default is quick bring-up. To enable
Enhanced bring-up, select the Start Options in the
Configuration/Setup Utility program (see “Setup Utility
program” on page 329) then, enable Power On Status.
001
– Power-off the computer and all external devices.
– Check all cables and power cords.
– Make sure the system board is seated properly.
– Set all display controls to the middle position.
