POST Error Messages
If you get a POST text error message in reverse video, refer to the HP Server Navigator CD-ROM to get a
more detailed explanation and a possible solution.
If the server starts, but POST still reports an error message, clear the CMOS configuration, as described later
in this chapter.
NOTE HP recommends you correct the error before proceeding, even if the server appears to
start successfully.
