A Error Messages and Indicators

Desktop board D915GMH 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 15 lists the BIOS codes.
