using 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 results in a consistent
deployment of and greater control over ROM images over the network.
All ROMPaq ROM images from HP are digitally signed to ensure authenticity and minimize
potential corruption. Your system ROM may include a Boot Block that is protected during the
flash process and allows the workstation to be restarted, in the unlikely event of an unsuccessful
ROM flash.
Your workstation must be powered on, or turned on through Remote Wakeup, to take
NOTE:
advantage of Remote ROM Flash. Use of Remote ROM Flash also requires an established setup
password.
For more information on enabling Remote ROM Flash, refer to the online Remote Management
Administrators Guide. The Remote Management Administrators Guide is included with the
Remote Management Setup Utilities, and is available on the HP Web site 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.
When the Boot Block detects an invalid system ROM, the system sounds a series of beeps (one
long and three short) and flashes the three keyboard lights (on and off two times). A Boot Block
recovery mode message is displayed on the screen.
To recover the system after it enters Boot Block recovery mode, complete the following steps:
1. Remove any diskettes from the diskette drive and turn off the power.
2. Insert a ROMPaq diskette into the diskette drive.
3. Turn on power to the system.
4. If no ROMPaq diskette is found, you will be prompted to insert one and restart the
workstation.
5. If a setup password has been established, the Caps Lock light will turn on and you will be
prompted to enter the password.
6. Enter the setup password.
7. If the system successfully starts from the diskette and successfully reprograms the ROM,
then the three keyboard lights will turn on. A "rising tone" series of beeps also signals
successful completion.
