BIOS Recovery by Crisis Disk

BIOS Recovery Boot Block

The BIOS Recovery Boot Block is a special block of BIOS. It is used to boot up the system with minimum BIOS initialization. Users can enable this feature to restore the BIOS firmware if a previous BIOS flashing process has failed.

BIOS Recovery Hotkey

To enable the BIOS Recovery process, use the function hotkey, <Fn+Esc>, during BIOS POST. The AC adapter and battery are required to be installed during this process.
