Position Default
8 Off
CAUTION: When maintenance mode is turned on (the maintenance switch is set to
on/closed) and the system is powered up, NVRAM configuration is invalidated.
Enabling ROMPaq Disaster Recovery Mode
A corrupted system ROM requires you to recreate the ROM BIOS by using the ROM
Flash Utility. This can be accomplished only when the system is in disaster recovery
mode. Set configuration switches 1, 4, 5, and 6 on the system maintenance switch
block to "on" to enable disaster mode.
IMPORTANT: Before enabling ROMPaq disaster recovery mode, refer to the HP Servers
Troubleshooting Guide for complete instructions on disaster recovery.
