A Error Messages and Indicators Desktop Board D845EPI 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 37. 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.
Intel Desktop Board D845EPI Product Guide BIOS Error Messages When a recoverable error occurs during the POST, the BIOS displays an error message describing the problem. Table 38. BIOS Error Messages Error Message Explanation GA20 Error An error occurred with Gate-A20 when switching to protected mode during the memory test.
