BIOS Recovery
Should you experience compatibility or stability issues with your Server, HP recommends starting your
troubleshooting by first updating your BIOS, which may fix your current problems. If the BIOS has become
corrupted, it is possible to perform a BIOS reset, recovery, or update to correct the condition. A BIOS
update/recovery diskette is created when the most current BIOS is downloaded from the HP web site to be
used in flashing the BIOS into the Server. To perform a reset, an update, or a BIOS recovery, perform one of
the following procedures.
