A Board Status and Error Messages

This appendix describes status error messages generated by the Desktop Board’s BIOS. The BIOS indicates these error messages with LED blink codes, speaker beep codes, and by text displayed on the PC monitor.

Front-panel Power LED Blink and Internal Speaker Beep Codes

Basic status and error messages are provided through the front-panel power LED blink codes as well as through audible beep codes on systems with an internal speaker connected to the internal speaker header. Blink/beep codes represent their respective messages as shown in Table 25.
