How to Recover the AMIBIOS Image (the Main
BIOS Block)
An AMIBIOS flash 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 flash a new BIOS
image if the original BIOS Image is corrupted. When the system is powered on, the
boot sector code executes first. Once it is completed, the main BIOS code will con-
tinue with system initialization and complete the bootup process.
B.10.2
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 flash
device, and name the file “SUPER.ROM” for the recovery process to load the file. A
USB flash 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 files)
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.
Caution:
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.
Note:
BIOS Recovery described below is used when the main BIOS block crash-
es. However, when the BIOS Boot sector crashes, you will need to send the moth-
erboard back to Supermicro for RMA repairs.
