PhoenixBIOS beep codes
http://www.phoenix.com/en/customer+services/bios/phoenixbios/default1.htm
Unfortunately, PhoenixBIOS beep codes are significantly more complicated than other BIOS
manufacturers. Instead of a single beep code set, PhoenixBIOS codes consist of a series of beep code
sets separated by a short pause. Older Phoenix BIOS Plus and PhoenixBIOS 1.x systems used a series
of three sets, while the PhoenixBIOS 4.x systems use a series of four sets. The codes listed below are
only some of the more than 100 codes for the PhoenixBIOS 4.x. For a complete list of Phoenix BIOS
POST task routines and beep codes, please visit their Web site or review your motherboard's
documentation.
