A Error Messages and Indicators

Desktop Board D5400XS reports POST errors in three ways:
• By sounding a beep code
• By displaying an error message on the monitor
• By displaying diagnostic progress codes (POST codes)

BIOS Beep Codes

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.
