Intel MB440LX manual Error and Informational Messages, Post Beep Codes, 213

Error and Informational Messages

When you turn on the system, POST displays messages that provide information about the system. If a failure occurs, POST emits beep codes that indicate errors in hardware, software, or firmware. If POST can display a message on the video display screen, it causes the speaker to beep twice as the message appears.

POST Beep Codes

Beep codes are a series of individual beeps, each one equal in length. Write down the beep code you hear; this information is useful for your service representative.
