Flashing the Latest Version of the System BIOS
BIOS upgrades can be downloaded, on to flexible diskette, from the
HP World Wide Web site:
http://www.hp.com/go/vectrasupport/
Following the instructions which you are given, you will obtain the flash
utility programs,
FLASH.BAT, AUTOEXEC.BAT and PHLASH.EXE programs,
the BIOS file, <bios file>
.FUL, and the platform file <platform file>.bin, on
a bootable flexible diskette.
Insert the flexible diskette into drive A. Re-boot the system. Enter the
command
FLASH <bios file>.FUL .
Crisis Recovery
Although the BIOS flash process is very well protected, there is always a
possibility of a failure (for example, due to a power failure during the BIOS
flash). To avoid replacing the motherboard due to corrupted EEPROM, a
crisis recovery function has been created to restore the contents.
1 Create a bootable flexible disk and copy phlash.exe , the platform file and
your bios image file to the disk.
2 Create a new autoexec.bat with the following line in it:
phlash /V /mode=3 /b=<platform file>.bin /exit <bios file>.ful
3 Toggle motherboard switch 9 to the CLOSED position.
4 Insert the flexible disk.
5 Power on the system and hear it flash (no image is shown!). The last long
beep indicates the end of the flashing.
6 Power off the system.
7 Toggle back switch 9 to the OPEN position, then remove the flexible disk.
The BIOS is now recovered and updated.
NOTE • The power button is not protected in recovery flashing mode. However,
since
/pf=b option is not used, we don't flash the bootblock, thus shutting
down during the phlash update is not critical.
• Flashing in recovery mode is blind (no video is displayed), except if you
install an external ISA video card.
