The HP EFI applications and preboot applications provide extensive preboot functions to the system BIOS residing in the

flash ROM. You can find information for GUID Partition Table (GPT) formatted disks on page four of this document.

NOTE: Do not encrypt the HP_TOOLS partition using software encryption programs such as Windows BitLocker or Full

Volume Encryption for HP ProtectTools. When the partition is encrypted, the HP preboot applications cannot function.

HP System Diagnostics during startup

The HP System Diagnostics, accessible during computer startup, allows you to perform tests on the primary hard drive

and system memory modules. You can also use this tool to obtain computer-related information such as model number,

processor type, total memory, and serial number.

BIOS recovery

The BIOS Recovery utility is a notebooks-only feature that allows you to recover the BIOS image if it becomes corrupted.

You can use BIOS Recovery in two ways:

 On notebooks, you can automatically detect a corrupted BIOS and repair it by flashing the BIOS image. A BIOS

Recovery utility is not included on desktops. If the BIOS on a desktop is corrupted during a flash, the next boot will

automatically enter a recovery mode (signaled by an 8-blink/beep POST error indication), and the system will look for

a USB storage device with the BIOS binary file in the root directory, or in the root of the HDD. It will then reflash the

system to recover.

 You can force the recovery on notebooks with the BIOS recovery utility. Again, desktops recover automatically when a

a corrupt BIOS is detected without the recovery utility.

Initially, the notebook BIOS recovery directory 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) will automatically perform updates with

the most current version of the BIOS. Note that the current version of the eROMPAQ flash utility does not support this

function. Since desktops do use a recovery utility, the BIOS flash utilities are not required.

Launching EFI applications

You can launch EFI applications using the following utilities:

 System Diagnostics (Both notebooks and desktops) – During startup, press the Esc key when the “Press Esc for

startup menu” message is displayed. 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 (Notebooks only) – While booting the computer, 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 system partition functionality, you must create a FAT32

partition named HP_TOOLS. Failure to do so results in the loss of the following features:

 Automatic BIOS corruption detection and recovery

 Ability to use all System Diagnostics functions

EFI architecture

Use caution when modifying the HP_TOOLS partition. The partition is not protected and can be deleted. Backing up the

computer using the Windows Complete PC Backup does not back up the EFI partition. With no EFI partition backup,

corruption or failure of the partition will result in loss of all data on the partition, plus loss of EFI functionality. HP

recommends that you do not place additional data on the EFI partition.

Volume name

The volume name is HP_TOOLSxxxx. HP_TOOLS in the initial release and the version number (represented here by

“xxxx”) at the end of the volume name is for future expansion and is under the control of the HP Preinstall team and

subject to change. Software should not hard code the volume version. Instead, software should search for the

“HP_TOOLS” prefix and identify the Fat32 HP partition using the prefix only.
