7-7 BIOS Recovery
Warning! Do not upgrade the BIOS unless your system has a BIOS-related issue.
Flashing the wrong BIOS can cause irreparable damage to the system. In no event shall
Supermicro be liable for direct, indirect, special, incidental, or consequential damages
arising from a BIOS update. If you need to update the BIOS, do not shut down or reset
the system while the BIOS is updating. This is to avoid possible boot failure.
How to Recover the AMIBIOS Image (-the Main BIOS
Block)
An AMIBIOS ash chip consists of a boot sector block, and a main BIOS code block
(a main BIOS image). The boot sector block contains critical BIOS code, including
memory detection and recovery code to be used to ash a new BIOS image if the
original BIOS Image is corrupted. When the system is powered on, the boot sector
code executes rst. Once it is completed, the main BIOS code will continue with
system initialization and complete the bootup process.
Note: BIOS Recovery described below is used when the main BIOS block
crashes. However, when the BIOS Boot sector crashes, you will need to send the
motherboard back to Supermicro for RMA repairs.
Boot Sector Recovery from a USB Device
This feature allows the user to recover a BIOS image using a USB device without
additional utilities needed. A user can download the BIOS image into a USB ash
device, and name the le "SUPER.ROM" for the recovery process to load the le.
A USB ash device such as a USB Flash Drive, a USB CDROM or a USB CDRW
device can be used for this purpose,
1. Insert the USB device that contains the new BIOS image (the ROM les)
saved in a root directory into your USB drive.
2. While turning the power on, press and hold <Ctrl> and <Home> at the same
time until the USB Access LED Indicator comes on. This might take a few
seconds.
3. Once the USB drive LED is on, release the <Ctrl> and <Home> keys.
AMIBIOS will issue beep codes to indicate that the BIOS ROM le is being
updated.
4. When BIOS ashing is completed, the computer will reboot. Do not interrupt
the ashing process until it is completed.
