Desktop Board D915GEV/D915GUX/D915GAV/D915GAG reports POST errors in two ways: 
•  By sounding a beep code 
•  By displaying an error message on the monitor 

The BIOS also issues a beep code (one long tone followed by two short tones) during POST if the 
video configuration fails (a faulty video card or no card installed) or if an external ROM module 
does not properly checksum to zero.  Table 16 lists the BIOS codes.
