Rom Flash - HP xw4200 Service And Technical Reference Manual

ROM Flash

The workstation comes with 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 workstation. Should you
need or want to upgrade the ROM, you may:
Order an upgraded ROMPaq diskette from HP.
Download the latest ROMPaq images from HP driver and support page, http://www.hp.com/support/
files.
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.
Remote ROM Flash
Remote ROM Flash allows the system administrator to safely upgrade the ROM on remote HP
workstations directly from the centralized network management console. Enabling the system
administrator to perform this task remotely, on multiple workstations 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 workstation 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.
HPQFlash
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
workstation when prompted.
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.
NOTE Some models also support recovery from a ROMPaq CD. ISO ROMPaq images are included
with selected models in the downloadable ROM softpaqs.
