What if the PC does not complete the BIOS or ME flash process? HP business PC products provide flash disaster recovery if the BIOS flash process fails to complete. The BIOS will automatically detect that the BIOS flash process did not properly complete and boot in recovery mode. With most business PC models, the user or administrator will be presented with the following screen. It will boot the PC in a recovery mode and search the root directory of the removable media sources (USB, or CD) for a compatible binary image. The BIOS.iso file, included in the softpaq, should be used to create a BIOS image CD if the user or administrator desires to use CD media for BIOS recovery. When flashing during recovery, the CD media, containing the BIOS image file, must be El-Torito compatible. USB media source can simply contain the BIOS binary image file in the root directory. Once a binary image is located, the BIOS update process will be attempted again. The automatic flash recovery will continue until the BIOS is successfully updated or restored. If no binary image is found, the PC will attempt to boot to diskette or USB flash media. The boot media must have DOS for the disaster recovery mode to successfully boot. The ME upgrade process in controlled by the Management Engine. If the upgrade process is not successfully completed or the attempted upgrade image is corrupted, the ME will abort the process and continue with its current firmware image. What is a processor microcode update softpaq and how is it used? Typical processors download code from the BIOS during initialization referred to as microcode. If a new, supported processor is installed in the business PC which requires a microcode currently not adequately provided by the BIOS, the BIOS will issue a POST warning "1801-Microcode Update Error".

What if the PC does not complete the BIOS or ME flash process?
HP business PC products provide flash disaster recovery if the BIOS flash process fails to complete. The
BIOS will automatically detect that the BIOS flash process did not properly complete and boot in recovery
mode. With most business PC models, the user or administrator will be presented with the following
screen.
It will boot the PC in a recovery mode and search the root directory of the removable media sources
(USB, or CD) for a compatible binary image. The BIOS.iso file, included in the softpaq, should be used to
create a BIOS image CD if the user or administrator desires to use CD media for BIOS recovery. When
flashing during recovery, the CD media, containing the BIOS image file, must be El-Torito compatible.
USB media source can simply contain the BIOS binary image file in the root directory. Once a binary
image is located, the BIOS update process will be attempted again. The automatic flash recovery will
continue until the BIOS is successfully updated or restored.
If no binary image is found, the PC will attempt to boot to diskette or USB flash media. The boot media
must have DOS for the disaster recovery mode to successfully boot.
The ME upgrade process in controlled by the Management Engine. If the upgrade process is not success-
fully completed or the attempted upgrade image is corrupted, the ME will abort the process and continue
with its current firmware image.
