»Notice

If you encounter problems while updating the new BIOS, DO NOT turn off your system since this corrupt BIOS might cause your system failed to boot up. Just repeat the process, and if the problem still persists, update the original BIOS file. 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 service.
