9.1 BIOS Recovery Jumper
When the BIOS Recovery jumper block is moved from its default pin position, the system will
boot into a BIOS Recovery Mode. It is used when the system BIOS has become corrupted and
is non-functional, requiring a new BIOS image to be loaded on to the server board.
Note: The BIOS Recovery jumper is ONLY used to re-install a BIOS image in the event the
BIOS has become corrupted. This jumper is NOT used when the BIOS is operating normally
and you need to update the BIOS from one version to another.
The following steps demonstrate the BIOS recovery process:
1. After downloading the latest System Update Package (SUP) from the Intel
®
Web site,
copy the following files to the root directory of a USB media device:
- IPMI.EFI
- IFlash32.EFI
- RML.ROM
- ####REC.CAP (where #### = BIOS revision number)
- STARTUP.NSH
2. Power OFF the system.
3. Locate the BIOS Recovery Jumper on the server board and move the jumper block from
pins 1-2 (default) to pins 2-3 (recovery setting).
4. Insert the recovery media into a USB port.
5. Power ON the system.
6. The system will automatically boot into the embedded EFI Shell.
