BIOS Recovery
If the BIOS becomes corrupted, it is possible to perform a BIOS recovery to correct the condition. A BIOS
Update diskette must be created from the HP NetServer Navigator CD-ROM to be used in flashing the new
BIOS into the NetServer. To update the BIOS, you enable the Boot Block by setting the Boot Block switch
(switch 7) of the configuration switch on the system board assembly to the ON (enabled) position.
To perform a BIOS recovery:
1. Power down the HP NetServer and gain access to the system board assembly.
2. On the system board, set the Boot Block switch (Switch 7), on the configuration switch, from
OFF to ON.
