WARNING!
If you encounter problems while updating the new BIOS, DO NOT
turn off your system since this might prevent your system from booting up. Just
repeat the process, and if the problem still persists, update the original BIOS file
you saved to disk above. If the Flash Memory Writer utility was not able to
successfully update a complete BIOS file, your system may not be able to boot
up. If this happens, your system will need servicing.
