Intel Desktop Board DX79TO reports POST errors in three ways: 
•  By sounding a beep code and blinking the front panel power LED 
•  By displaying an error message on the monitor 
•  By displaying diagnostic progress codes (POST codes) 

Whenever a recoverable error occurs during POST, the BIOS causes the board’s 
speaker to beep and the front panel power LED to blink an error message indicating 
the problem (see Table 15).
