2.6.2.1BIOS Recovery Beep Codes

In rare cases, when the system BIOS has been corrupted, a BIOS recovery process must be followed to restore system operability. During recovery mode, the video controller is not 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. In the event of a failure, two short beeps are generated and a flash code sequence of 0E9h, 0EAh, 0EBh, 0ECh, and 0EFh appears at the Port 80 diagnostic LEDs (see Table 2-14 on page 2-30).
