2.8 ROMPaq
The Compaq Deskpro 4000S and 4000N Personal Computers come 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 or download it from the Compaq
World Wide Web site.
2.8.1 Deskpro 4000S
To upgrade the ROM, complete the following steps:
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.
4. 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 will
corrupt the upgrade and will require recovery using the FailSafe Boot Block ROM.
5. When the utility has finished upgrading the ROM, remove the diskette from the diskette drive
and reboot the computer.
