Recovering the UEFI firmware
If the UEFI firmware has become damaged, such as from a power failure during an
update, you can recover the UEFI firmware using the boot block jumper and a UEFI
recovery diskette.
The system board contains a backup copy area for the server firmware. This is a
secondary copy of the server firmware that you update only during the process of
updating the server firmware. If the primary copy of the server firmware becomes
damaged, use this backup copy.
To force the server to start from the backup copy, turn off the server; then, place the
J29 jumper in the backup position (pins 2 and 3).
Use the backup copy of the server firmware until the primary copy is restored. After
the primary copy is restored, turn off the server; then, move the J29 jumper back to
the primary position (pins 1 and 2).
