BIOS Recovery

AMIBIOS supports a "recovery flash" mode, which can be used to flash update a BIOS from the boot block.

This is used to update a BIOS image without the need to boot to an operating system. The following is the

process that user should follow to flash BIOS ROM.

1. Put the AMIBoot.ROM to a bootable USB flash drive(Disk on Key, DOK).

2. Install the DOK to the system.

3. Press power button to boot the system and then press Ctrl + Home.

4. The BIOS recovery function will be executed.

5. After BIOS is updated completely, the system will auto reboot.

6. Please enter the setup menu to load default after system reboot.
