initialization. Users can enable this feature to restore the BIOS firmware to a successful one once the previous

, for enable BIOS Recovery process when system is powered
on during BIOS POST. To use this function, it is strongly recommended to have the AC adapter and Battery

executing the Crisis Disk program in another system with Windows XP OS.
Follow the steps below:
1.
Power Off failed system.
2.
Attach a USB floppy drive to the failed system.

Insert the Crisis Disk in to the USB floppy drive attached to the BIOS flash failed system.
4.
In the power-off state, press and hold
Fn+Esc
then press the Power button.
The system powers on and the Crisis BIOS Recovery process begins.

systems.
When the Crisis flash process is finished, the system restarts with a workable BIOS.

Update to the latest version BIOS for the system using the regular BIOS flashing process.
