BIOS Recovery by Crisis Disk BIOS Recovery Boot Block

The BIOS Recovery Boot Block is a special block of BIOS which 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 in the case that the BIOS flashing process fails.

BIOS Recovery Hotkey:

The system provides a function hotkey: Fn+Esc, for enabling the BIOS Recovery process when the system is powered on during BIOS POST. To use this function, it is strongly recommended to have both the AC adapter and Battery plugged in. If this function is enabled, the system will force the BIOS to enter a special BIOS block called Boot Block.

Steps for BIOS Recovery using a USB crisis disk:

A USB crisis disk can be used to recover system BIOS in the event of the BIOS being corrupted. To create the crisis disk use the following steps:

  1. Plug in a USB flash disk. Back up any information on the disk, as this process will format your USB flash disk.
  2. Launch the wincris.exe program to create a USB Crisis Disk. Click Start to initiate the process.
  3. Select the Quick Format option to format the disk and click Start. Follow the instructions on the screen to create the disk.
  4. Copy the KAYF0X64.fd BIOS file into the USB flash disk root directory. NOTE: Do not place any other *.fd file in the USB flash disk root directory.

To use the Crisis USB key, do the following:

  1. Plug the USB flash disk into a USB port.
  2. Press Fn + ESC button then plug in AC power. The Power button flashes orange once.
  3. Press Power button to initiate system CRISIS mode.

When CRISIS is complete, the system auto restarts with a workable BIOS.

4. Update to the latest version of BIOS for this machine by the regular BIOS flashing process.
