A Error Messages and Indicators
Intel Desktop Board DX58SO2 reports POST errors in three ways:
•By sounding a beep code and blinking the front panel power LED
•By displaying an error message on the monitor
•By displaying diagnostic progress codes (POST codes)
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 15).
