Error beep codes
BIOS POST error beep codes
The following table lists the POST error beep codes. Prior to system video initialization, BIOS uses these beep codes to inform you of error conditions. The beep code occurs only when a critical error occurs or when the BIOS fails to boot to the operating system. Not all error conditions are supported by the BIOS beep codes.
