2.10 ROMPaq

The Compaq Deskpro 2000 Series of Personal Computer comes with reprogrammable Flash ROM

(Read Only Memory). Flash ROM Lock, set to its default setting of OFF,

protects the Flash ROM

from being upgraded and the system BIOS from being updated.

To update the ROM, order the ROMPaq diskette from Compaq. Then complete the following

procedures:

1. Insert the ROMPaq diskette into the diskette drive.

2. Turn on the computer.

CAUTION:

If the computer does not have a Setup Password enabled, then the ROM is not write-

protected and unauthorized updates can occur. The Setup Password is disabled when the computer is

shipped from the factory.

3. If prompted, enter the Setup Password.

If the Setup Password is entered correctly, the ROMPaq utility takes over and runs the Flash

ROM upgrade.

If the Setup Password is entered incorrectly, the procedure terminates and no changes are

made to the ROM.

CAUTION:

Do not turn the power off during a firmware upgrade.

A loss of power during upgrade might

corrupt the upgrade.

When the utility has finished upgrading the ROM, remove the diskette from the diskette drive

and reboot the computer.
