General checkout - PC 300 - 6563/6564/6565/6574/6868/6878

Note: Service information is the same for types 6563/6564/6565/6574/6868/6878 computers, unless specifically identified as type 6563 which is the desktop computer.

Note: This manual and the diagnostic tests are intended to test only IBM products.
Non-IBM products of any kind including adapter cards, accelerator boards, options, or non-IBM devices, can give false errors and invalid computer responses.
If you remove a non-IBM device and the symptom goes away, the problem is with the device you removed.

This general checkout procedure is for Type 6563/6564/6565/6574/6868/6878 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'.

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.
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.
4.  If the computer hangs and no error is displayed, go to Undetermined Problems.
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') then, enable Power On Status.
