When the Boot Block detects an invalid system ROM, the System Power LED blinks red eight times,
once every second, followed by a two-second pause. Also, you will hear eight beeps that correspond
to the blinks. A Boot Block recovery mode message is displayed on the screen (some models).
To recover the system after it enters Boot Block recovery mode:
1. If a removable medium is loaded in the workstation, remove it and power down the workstation.
2. Insert the appropriate ROMPaq removable medium in the workstation.
3. Power on the workstation.
If no ROMPaq removable medium is found, you are prompted to insert one and restart the
workstation.
If a setup password has been established, the Caps Lock light illuminates and you are prompted
to enter the password.
4. Enter the setup password.
If the system successfully starts from the removable medium and successfully reprograms the
ROM, the three keyboard lights illuminate.
5. Remove the removable medium and restart the system.
The following table lists the various keyboard light combinations used by the Boot Block ROM (when a
PS/2 keyboard is attached to the workstation) and explains the meaning and action associated with
each combination.

Replicating the setup
The following procedures enable you to easily copy one setup configuration to other workstations of the
same model to provide faster, more consistent configuration of multiple workstations.
NOTE Setup configuration procedures require a diskette or a USB such as an HP DriveKey.
To collect and replicate BIOS settings on multiple computers, use System Software Manager or
HP Client Manager Software. For more information, see
