Updating the system

ROM

4Power on the computer.

5During the recovery process, short beeps are emitted. The recover process is finished when there is a much longer beep (after approximately 1 to 2 minutes).

6Power off the computer. Press the power ON/OFF button (for about 5 seconds), until the ON/OFF light switches off. Set the switch 9 to the Open position.

The System ROM can be updated with the latest BIOS firmware. This can be downloaded from HP’s World Wide Web site:

To download a BIOS upgrade, connect to the HP Web site and follow the on- screen instructions to download the flash utility programs (FLASH.BAT, AUTOEXEC.BAT and PHLASH.EXE), the BIOS file (HC11xx.FUL), and a file called pfmhd106.bin, onto a bootable diskette.

Before updating the System ROM, it is necessary to disable the “PSWRD” switch on the system switches (SW-7), and to type in the System Administrator’s Password when starting up the computer. The PCI and PnP information is erased in the process.

Do not switch off the computer until the system BIOS update procedure has completed, successfully or not, otherwise irrecoverable damage to the ROM may be caused. While updating the flash ROM, the power supply switch and the reset button are disabled to prevent accidental interruption of the flash programming process.
