SUMMARY
American Megatrends, Inc. (AMI) BIOS will produce audible beeps associated with beep codes during the power-on self test (POST). Depending upon the condition, a predefined number of beeps are sounded, which are associated with the error messages below.

NOTE: Some systems produce beeps as part of the normal boot sequence. This article refers to beeps produced by the AMI ROM BIOS before the operating system loads.

MS-DOS does not produce beep codes.
