POST Error Messages
If you get a POST text error message in reverse video, press Enter (View System Error) 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.
