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

Remote ROM Flash
Remote ROM Flash allows the system administrator to safely upgrade the BIOS 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.
NOTE: SSM does not currently support remote ROM flash on systems that have Windows Vista
BitLocker enabled and are using TPM measurements to protect the BitLocker keys because flashing
the BIOS would invalidate the trust signature that BitLocker created for the platform. Disable BitLocker
via Group Policy in order to flash the system BIOS.
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

HPQFlash
The HPQFlash utility is used to locally update or restore the system BIOS of individual PCs from a
Windows operating system.
For more information on HPQFlash, visit
http://www.hp.com/support/files and enter the model number
of the computer when prompted.
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.
When an invalid system BIOS image is detected, the system power LED will blink red 8 times, one blink
every second. Simultaneously, the speaker will beep 8 times. If the portion of the system ROM containing
the video option ROM image is not corrupt, Boot Block Emergency Recovery Mode will be displayed
on the screen.
