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 17. These beep codes can be heard through a speaker attached to the
board’s line out audio jack (see Figure 3, B on page 17) or the piezoelectric speaker
header (see Figure 12, D).
