BIOS Recovery

BIOS Recovery is a utility that allows you to recover the BIOS image if it becomes corrupt. BIOS
Recovery can be employed in two ways. It can automatically detect and repair a corrupted BIOS by
flashing the BIOS image that is stored on the partition into the flash ROM. It can also be used to force
a BIOS recovery.
Initially, the BIOS recovery directory on the EFI partition contains the first released version of the BIOS
for the platform. Later, as HP releases BIOS updates, two HP BIOS flash utilities (HPQFlash and SSM
flash) automatically update the partition with the most current version of the BIOS. Note that the
current version of the eROMPAQ flash utility does not support this function.

Launching EFI applications

Launch EFI applications as follows:
Quick Look: Press the info button to start QuickLook from the off state (S5) or Hibernation (S4). If
QuickLook is disabled in BIOS, the button is inactive while the computer is off, in the Sleep state, or
in Hibernation.
HP Note
Pressing the info button when the system is in the Sleep state
(S3) does not launch QuickLook or Info Center. Rather, the
computer returns to the state it was in prior to entering the Sleep
state.
System Diagnostics: Press the Esc key when the "Press Esc for startup menu" message displays when
you boot the computer. Then press F2 to launch System Diagnostics. F2 will not wake the system
from the off state or the Sleep/Hibernation state. F2 can be used only during POST when the BIOS
keys are displayed.
BIOS Recovery: Hold down the four arrow keys, and then press the power button to launch BIOS
Recovery.

EFI and custom imaging

If you use your own custom image and you want to maintain EFI partition functionality, you must
create a FAT32 partition named HP_TOOLS. Failure to do so results in the loss of the following
features:
Ability to start QuickLook by pressing the info button
Automatic BIOS corruption detection and recovery
Ability to use all System Diagnostics functions
