3.4 ROM Flash

The computer comes with a reprogrammable flash ROM (read only memory). By establishing a
setup password in Computer Setup (F10) Utility, you can protect the ROM from being
unintentionally updated or overwritten. This is important to ensure the operating integrity of the
computer. Should you need or want to upgrade your ROM, you may:

■

Order an upgraded ROMPaq diskette from HP.

■

Download the latest ROMPaq images from

http://www.hp.com/support

.

Ä

CAUTION:

For maximum ROM protection, be sure to establish a setup password. The setup password

prevents unauthorized ROM upgrades. System Software Manager allows the system administrator to set

the setup password on one or more PCs simultaneously. For more information, visit

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

3.4.1 Remote ROM Flash

Remote ROM Flash allows the system administrator to safely upgrade the ROM on remote HP
computers directly from the centralized network management console. Enabling the system
administrator to perform this task remotely, on multiple computers and personal computers,
results in a consistent deployment of and greater control over HP PC ROM images over the
network.

✎

The computer must be powered on, or turned on through Remote Wakeup, to take advantage of
Remote ROM Flash.

For more information on Remote ROM Flash, refer to the HP Client Manager Software or
System Software Manager at

http://h18000.www1.hp.com/im/prodinfo.html

3.4.2 HPQ Flash

The HPQFlash utility is used to locally update or restore the system ROM on individual PCs
through a Windows operating system.

For more information on HPQFlash, visit

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

and enter the name

of the computer when prompted.
