BIOS POST Beep Codes

The table below lists the POST error beep codes. Prior to system video initialization, the BIOS uses
these beep codes to inform users of error conditions. The beep code occurs only when a critical
error occurs or when the BIOS fails to boot to the operating system. Please note that not all error
conditions are supported by the BIOS beep codes.
