3.4 ROM
Flash
The computer's BIOS is stored in a programmable flash ROM (read only memory). By
establishing a setup password in the 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 the BIOS, you may download the
latest BIOS images from the HP driver and support page:

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
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 results in a consistent
deployment of, and greater control over, HP PC BIOS images over the network. It also results in
greater productivity and lower total cost of ownership.
✎
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 or System
Software Manager at

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

name/number of the computer when prompted.
3.4.3 Boot Block Emergency Recovery Mode
Boot Block Emergency Recovery Mode permits system recovery in the unlikely event of a ROM
flash failure. For example, if a power failure were to occur during a BIOS upgrade, the ROM
flash would be incomplete. This would render the system BIOS unusable. The Boot Block is a
flash-protected section of the ROM that contains code that checks for a valid system BIOS image
when the system is turned on.
■
If the system BIOS image is valid, the system starts normally.
■
If the system BIOS image is not valid, a failsafe Boot Block BIOS provides enough
support to:
❏
search removable media for BIOS image files. If an appropriate BIOS image file is
found, it is automatically flashed into the ROM.
❏
start the system from bootable removable media that automatically invokes system BIOS
upgrade utilities.
