A Error Messages and Indicators

Intel Desktop Board DH55HC reports POST errors in two ways:
• By sounding a beep code and blinking the front panel power LED
• By displaying an error message on the monitor

BIOS Error 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 17).
