BIOS Recovery by Crisis Disk

BIOS Recovery Boot Block:

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 to a successful one once the previous

BIOS flashing process failed.

BIOS Recovery Hotkey:

The system provides a function hotkey: Fn+Esc, 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

present. 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, one Crisis Disk should be prepared ready in hand. The Crisis Disk could be made by

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.

3. 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.

BIOS Boot Block begins restoring the BIOS code from the Crisis floppy disk to BIOS ROM on the failed

systems.

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

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