BIOS Beep Codes

[Embattle]

It depends on your BIOS manufacturer but below are links to the lastest information on what the different beeps mean:

AMI BIOS - http://www.ami.com/support/doc/AMIBIOS-codes.pdf
Phoenix BIOS - http://www.phoenix.com/resources/bios-postcode.pdf

Both are PDF files, the third BIOS is an Award BIOS but this is what they post regarding beeps:

The only AwardBIOS beep code indicates that a video error has occurred and the BIOS cannot initialize the video screen to display any additional information. This beep code consists of a single long beep followed by two short beeps. Any other beeps are probably a RAM (Random Access Memory) problem.
