BIOS Update Crisis Recovery Procedure
If, for example, during a BIOS update process, the process is interrupted by a power
failure, and the system does not start, you can still recover the situation of a destroyed
system BIOS. However, it should be noted that during the recovery procedure, there is no
image on the screen, nor access to the keyboard or mouse (only "vital" devices that are
required to boot on the floppy are initialized). Follow these steps to recover the BIOS:
1. Ensure that you have created a DOS-bootable diskette. This floppy diskette contains all
the recovery and system BIOS programming software (phlash.exe, platform.bin and
HO1xyyzz.Ful). Include the flash command in the first line of autoexec.bat, for example:
phlash
/c HO1xyyzz.Ful
H = HP Professional PC
O = HP V

1 = HP Division that provides the platform. In this case, it is PDCO
x = major revision
yy = minor revision
zz = language
NOTE
Setting Switch 10 to the Closed position also enables the MaxiLife firmware
'crisis' block if the power cord is unplugged (after approximately 30 seconds).
In this case, the LCD status panel is not available and the screen is blank.
2. Turn off the computer. Set Switch 10 to the Closed position.
3. Insert the DOS-bootable diskette.
4. Turn on the computer.
5. During 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).
6. Power off the computer. Press the power ON/OFF button (for about 5 seconds), until the
ON/OFF light switches off. Set switch 10 to the Up position.
Other ISA Accessory Devices
ISA accessory boards are for slow peripheral accessories. A diagram showing the ISA slots
that are available for the HP V
Board Slots" in this chapter.
Plug and Play
All PCI accessory boards are Plug and Play, although not all ISA boards are. Check the
accessory board's documentation if you are unsure.
In general, in a Plug and Play configuration, resources for an ISA board have to be
reserved first (using the Setup utility). Then you can plug in your board.
