Obtaining the Upgrade
Download the BIOS image file to a temporary folder on your hard drive. See
System References" on page xi
Note: Before attempting a BIOS upgrade, review the instructions and release notes provided in
the readme file distributed with the BIOS image file. The release notes contain critical
information regarding jumper settings, specific fixes, and other information to complete
the upgrade.
Upgrading the BIOS
Follow the instructions in the readme file that came with the BIOS upgrade. When the
update completes, remove the bootable media from which you performed the upgrade.
Caution: Do not power down the system during the BIOS update process!
Note: You may encounter a CMOS Checksum error or other problem after reboot. If this
happens, shut down the system and boot it again. CMOS checksum errors require that you
enter Setup, check your settings, save your settings, and exit Setup.
Recovering the BIOS
If an update to the system BIOS is not successful or if the system fails to complete POST
and the BIOS is unable to boot an operating system, it may be necessary to run the BIOS
recovery procedure.
To place the baseboard into recovery mode, move the boot option jumper (located on the
baseboard) to the recovery position. The BIOS can then execute the recovery BIOS (also
known as the boot block) instead of the normal BIOS. The recovery BIOS is a self-
contained image that exists solely as a fail-safe mechanism for installing a new
BIOS image.
Note: During the recovery mode, video is not initialized. One high-pitched beep announces the
start of the recovery process. The entire process takes two to four minutes. A successful
update ends with two high-pitched beeps. Failure is indicated by a long series of
short beeps.
Recovering the BIOS
The following steps boot the recovery BIOS and flashes the normal BIOS:
1. Power down and unplug the system from the AC power source.
2. Move the recovery jumper from the default location at pins 1 and 2 to cover pins 2
and 3. For location of the jumper, see
22
for a link to the update software.
