BIOS Recovery by Crisis Disk
BIOS Recovery Boot Block:
BIOS Recovery Boot Block is a special block of the BIOS. It is used to boot up the system with minimum BIOS
initialization. Users can enable this feature to restore the BIOS firmware to a successful one once the previous
BIOS flashing process failed.
BIOS Recovery Hotkey
The system provides a function hotkey:
Fn+Esc
, for enabling the BIOS Recovery process at system power-on
during BIOS POST. To use this function, the AC adapter and the battery must be connected. If this function is
enabled, the system will force the BIOS to enter a special BIOS block called Boot Block.
Steps for BIOS Recovery by Crisis Disk
Before doing this, prepare a Crisis Disk (refer to the “Steps for Creating the Crisis Disk in Windows XP/Vista”
section below) and keep it ready in hand.
Follow these steps for BIOS recovery:
1.
Power off the system.
2.
Connect a removable USB storage device containing the Crisis Disk to a USB port connected to the BIOS
flash failed system.
3.
Under power-off state, press and hold
Fn+Esc
and then press the power button. The system should be
powered on with the Crisis BIOS Recovery process.
4.
BIOS Boot Block starts to restore the BIOS code from the Crisis Disk to BIOS ROM on the failed system.
5.
After the crisis flashing process is finished, the system will restart.
After the Crisis Recovery process is finished, the system should have a successful and workable BIOS after
power on. The user can then update the latest BIOS version for this system using the regular BIOS flashing
process.
Creating the Crisis Disk in Windows XP/Vista
Follow these steps to create the Crisis Disk:
1.
Prepare a removable USB storage device (size greater than 10MB). Note that all data on the USB
storage device will be cleared during the creation of the Crisis Disk.
2.
Set up another computer loaded with Windows XP or Vista operating system.
