Recovery BIOS will generate two beeps and flash a POST code sequence of 0E9h, 0EAh,
0EBh, 0ECh, and 0EFh on the POST Progress Code LEDs.
During recovery mode, video will not be initialized. One high-pitched beep announces the start
of the recovery process. The entire process takes two to four minutes. A successful update
ends with two high-pitched beeps. Failure is indicated by a long series of short beeps.
