Error And Informational Messages; Post Beep Codes - Intel MB440LX System Installation Manual

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.
