BIOS Recovery Beep Codes
In the case of a Bootblock update, where video is not available for text messages to be displayed, speaker
beeps are necessary to inform the user of any errors. The following table describes the type of error beep
codes that may occur during the Bootblock update.
Recovery BIOS will generate two beeps and flash 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
high-pitched beeps. Failure is indicated by a long series of short beeps.
