A Error Messages and Indicators
Desktop Board D865GBF/D865GLC reports POST errors in two ways:
• By sounding a beep code
• By displaying an error message on the monitor
BIOS Beep Codes
The BIOS beep codes are listed in Table 41. 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.
