POST Error Messages List

If you cannot run the diagnostics program tests but did receive a POST error
message, use "POST Error Messages List" to diagnose system problems. If
you did not receive any error message, look for a description of your error
symptoms in "Error Symptoms List" on page 71.
CAUTION When you have deemed it necessary to replace a FRU, and have
done so, you must run a total system check to ensure that no other
activity has been affected by the change. This system check can be
done through the diagnostics program.
IMPORTANT Check all power supply voltages, switch, and jumper settings
before you replace the system board. Also check the power
supply voltages if you have a "system no-power" condition.
If you are unable to correct the problem by using the "BIOS Messages List" table
and "Error Symptoms List" table, go to "Undetermined Problems" on page 77.
NOTE To diagnose a problem, first find the BIOS error messages in left column.
If directed to a check procedure, replace the FRU indicated in the check
procedure. If no check procedure is indicated, the first Action/FRU listed
in right column is the most likely cause.
