Chapter 6: 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 Viglen 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 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 continue with system initialization and complete the bootup
process.
Notes:
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 Viglen for RMA
repairs.
