Jumper Name
Jumper Purpose
BIOS Recover
In the unlikely event the system BIOS gets corrupted, the system should automatically load an
embedded backup image of the BIOS. If for any reason the BIOS backup does not automatically get
installed, the BIOS recovery jumper can be used to force the system to boot to the uEFI shell and
allow for a manual BIOS update. With the system powered off, move the jumper block from pins 1-2
(default) to pins 2-3. Power on the system. The system will boot into the embedded uEFI shell
allowing for a BIOS update using the standard BIOS update files included in the System Update
Package (SUP). When the update has finished, power down the system and move the jumper block
back to its default position over pins 1-2.
ME Force Update
To place the system in a ME Force Update Mode, power off the system and move the jumper block to
pins 2-3. When set, this option will disable all but the essential Management Engine functions. The
default setting for this option is to have the jumper block installed over pins 1-2
Password Clear
To clear both the Administrator and User passwords (as set in BIOS Setup), power off the system and
move the jumper block to pins 2-3. Power on the system. The passwords are cleared within five to
ten seconds after the system is powered on. Power off the system and move the jumper block back
to its default position over pins 1-2.
