POST Error Messages
POST Error Message Table
The following table shows error messages that might appear on the
screen during the power-on self-test (POST).
Sometimes the first error to occur causes additional errors. In this
case, the system displays more than one error message. Always
follow the suggested action instructions for the first error message
that appears.
POST error codes are also written to the PS/2-standard logging area
in the Extended BIOS Data Area.
