Then remove the tool from the HW Gap. •Restart system. Press F2 key to enter BIOS Setup menu. •If there is no Password request, BIOS Password is cleared. Otherwise, please follow the steps and try again. NOTE: The steps are only for clearing BIOS Password (Supervisor Password and User Password).

172Chapter 5 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.
