5.3 BIOS FEATURES SETUP
The <BIOS FEATURES SETUP> option consists of configuration entries that allow you to improve your system performance, or let you set up some system features according to your preference. Some entries here are required by the CPU board’s design to remain in their default settings for optimal performance.
