3.4.2 HPQ Flash

Use the HPQFlash utility to locally update or restore the system ROM in individual PCs through
a Windows environment. For more information on HPQFlash, refer to the HP Client Manager
Software or System Software Manager at

3.4.3 FailSafe Boot Block ROM

The FailSafe Boot Block ROM allows for system recovery in the unlikely event of a ROM flash
failure, for example, if a power failure occurs during a ROM upgrade. The Boot Block is a
flash-protected section of the ROM that checks for a valid system ROM flash when power to the
system is turned on.
If the system ROM is valid, the system starts normally.
If the system ROM fails the validation check, the FailSafe Boot Block ROM provides
enough support to start the system from a ROMPaq diskette, which programs the system
ROM with a valid image.
Some models also support recovery from a ROMPaq CD.
When the bootblock detects an invalid system ROM, the System Power LED blinks RED eight
times, one every second, followed by a two-second pause. You will also hear eight simultaneous
beeps. A Boot Block recovery mode message is displayed on the screen (some models).
The beeps continue through five cycles of eight simultaneous beeps and stop; however, the LED
continues blinking until the issue is resolved.
To recover the system after it enters Boot Block recovery mode, complete the following steps:
1. If there is a diskette or a CD in the computer, remove the media and turn off the power.
2. Insert a ROMPaq diskette, bootable drive key, or CD.
3. Turn on power to the system.
4. If no ROMPaq diskette is found, you must insert one and restart the computer.
