PhoenixBIOS beep codes
|
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 new 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 newer 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.
