ROMPaq Disaster Recovery
A corrupted system ROM requires that you recreate the ROM BIOS by a process called
disaster recovery. This operation can be accomplished only when the system is in disaster
recovery (emergency repair boot) mode. When both system ROMs are corrupt, the system
defaults into disaster recovery mode automatically and the server emits two extended beeps.
IMPORTANT: Before performing this operation, refer to the HP Servers Troubleshooting Guide for
complete instructions on disaster recovery.
To perform ROMPaq disaster recovery:
1. Power down the server.
2. Set system maintenance switches 1, 4, 5, and 6 to the “on” position. For the location of
these switches, refer to Chapter 4, “Connectors, LEDs, and Switches.”
3. Power up the server. After the system powers on, it repeatedly emits two long beeps.
4. Power down the server again. If necessary, perform a forced shutdown by pressing the
power button for 4 seconds.
5. Set system maintenance switches 1, 4, 5, and 6 back to the default position (off).
6. Power up the system.
7. Insert a ROMPaq diskette with the latest system ROM that you have downloaded from
www.hp.com
IMPORTANT: The ROMPaq will flash both sides of the redundant ROM. This process may take
up to 10 minutes.
8. Wait until the server emits three rising beeps, indicating the completion of the ROM flash
process.
9. Restart the server.
