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 to the factory settings if a BIOS flash
process fails.
BIOS Recovery Hotkey
The system provides a function hotkey: Fn+Esc, to enable the BIOS Recovery process when a 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 from USB Storage
Before performing this procedure, prepare a Crisis USB key. The Crisis USB key can be made by executing
the Crisis Disk program in a functioning system with a Windows XP, Vista or 7 OS.
IMPORTANT:The Crisis Disk program will overwrite all data on any drive that you use as a crisis disk.
Follow the steps below:
1. Modify the archive name from ZE8 bios to ZE8X64.fd
2. Save ROM file (file name: ZE8X64.fd) to the root directory of the USB storage.
3. Plug the USB storage into a USB port of the machine to have the crisis utility run on.
4. Remove the battery and AC adaptor of the machine.
5. While pressing the Fn + ESC buttons plug in the AC adaptor and then press Power. Keep pressing
Fn+ESC till the power button flashes.
The LED of the USB flash disk flashes for three (3) to seven (7) minutes.
When CRISIS is complete, the system auto restarts with a workable BIOS.
6. Update the latest version BIOS for this machine by the regular BIOS flashing process.
