If the system BIOS becomes corrupted during the update process—for

procedure on page 197.

Recovering the BIOS

Moving the boot option jumper on J2C1 from pins 2(B-C) to pins 2(A-B) enables the BIOS flash
memory boot recovery mode. The BIOS can be corrupted—for example, when the update
procedure is aborted due to a power outage. However, flash memory contains a protected area that
cannot be corrupted. Code in this area is used to boot the server from drive A when the BIOS has
been corrupted. After booting, the Flash Update Utility (IFLASH) is used to automatically recover
the BIOS from the BIOS recovery files on the diskette.
To recover the BIOS:
1. Observe the precautions on page 115, “Safety Guidelines.”
2. Turn off the server, and unplug the AC power cords from the power supplies or wall outlets.
3. Remove the top and right side covers. See Chapter 12, “Server Covers:
Removing/Reinstalling.”
4. Move the jumper from J2C1 pins 2(B-C) to pins 2(A-B) to allow the server to boot from the
recovery BIOS.
5. Reinstall the top and side covers, plug in the power cords, and insert the Flash Update Utility
diskette in drive A.
