A Board Status and Error Messages

This appendix describes status and error messages generated by the Desktop Board's
BIOS. The BIOS indicates these error messages with front-panel Power LED blink
codes, speaker beep codes, and by displaying text on the video monitor.

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 12. These beep codes can be heard through a speaker attached to the board's
line out audio jack (see Figure 2, B on page 15).
