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. 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 Software or System Software Manager at

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 were to occur 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 will program the system ROM with a
valid image.
✎
Some models also support recovery from a ROMPaq CD.
When the boot block detects an invalid system ROM, 8 beeps will be
heard. A Boot Block recovery mode message is displayed on the
screen (some models).
✎
The beeps continue through five cycles of 8 beeps and stops.
