A Error Messages and Indicators<br />
Intel <strong>Desktop</strong> <strong>Board</strong> <strong>DH67CL</strong> reports POST errors in two ways:<br />
• By sounding a beep code and blinking the front panel power LED<br />
• By displaying an error message on the monitor<br />
BIOS Error Codes<br />
Whenever a recoverable error occurs during POST, the BIOS causes the board’s<br />
speaker to beep and the front panel power LED to blink an error message indicating<br />
the problem (see Table 15).<br />
