BIOS Beep Codes

The BIOS uses audible beep codes to signal status messages and error messages
indicating recoverable errors that occur during the POST. The beep codes are listed in
Table 37. These beep codes can be heard through a speaker attached to the board's
line out audio jack (see Figure 4, B on page 26).
