Recovering the BIOS

If an update to the system BIOS is not successful or if the system fails to complete
POST and BIOS is unable to boot an operating system, it may be necessary to run the
BIOS recovery procedure.
Note – Recovering the BIOS is the last resort, used only when the main system BIOS
will not boot or is corrupt.
Follow these steps to perform a BIOS recovery:
1. Turn off system power.
2. Remove the top cover of the server.
3. Move the RCVR\BOOT jumper located on the baseboard to the Recover position
(see Figure 4-40).
