Intel Motherboard DG35EC BLKDG35EC User Manual

 

63 

Desktop Board DG35EC 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 14 lists the BIOS 
codes.
