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.

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

http://www.hp.com/support/files

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.

3.4.4 Replicating Your Setup

To replicate or copy one setup configuration to other computers of the same model, HP has

provided a Windows-based software utility, System Software Manager, that you can download

from

http://www.hp.com/go/ssm

, plus a DOS-based software, CMOS Save/Load utility, that

can be downloaded from

http://www.hp.com/support/files

Web site, enter the name of your computer when prompted.
