Recovering from a BIOS Update Failure or BIOS Corruption 1 of 2
Although the BIOS update (flashing) process is very well
protected, there is always the possibility of a failure.
This may occur, for example, if there is a power failure
while the BIOS is being updated.
To avoid having to replace the system board due to
corrupted EEPROM, follow this recovery procedure to
restore the contents of EEPROM.
If you don’t already have the latest BIOS for you PC,
you can obtain it from HP’s support web site.
1 Create a bootable floppy disk in MS-DOS by typing
format a: /s.
2 Copy the BIOS image you require (for example,
IPxxyy.FUL, where xxyy corresponds to the BIOS
revision number), and phlash.exe and platform.bin
onto the bootable floppy disk.
3 Add the following line to the floppy’s
AUTOEXEC.BAT file:
phlash IPxxyy.FUL /c /mode=3 .
4 Remove the PC’s cover and set system board switch 3
(BIOS Block Recovery) to ON.
5 Replace the PC’s cover and insert the floppy disk into
the floppy drive.
6 Power on the PC to flash the BIOS. There will be many
beeps during the process. When this process is
complete, you will hear a long beep.
