The uEFI BIOS
EFI BIOS (ASUS EZ BIOS)
The new ASUS EFI BIOS is an Extensible Firmware Interface that complies with uEFI architecture, offering a user-friendly interface that goes beyond traditional keyboard-only BIOS controls to enable a way more flexible and convenient mouse input at BIOS level. uEFI (Unified Extensible Firmware Interface) is a specification detailing an interface that helps hand off control of the system for the pre-boot environment (i.e. after the system is powered on, but before the operating system starts) to an operating system, such as Windows. uEFI is an interface.
It can be implemented on top of a traditional BIOS (in which case it supplants the traditional "INT" entry points into BIOS) or on top of non-BIOS implementations. End-users can navigate the new EFI BIOS (basic input/output system) with the same smoothness as their operating system. It's simply a Windows OS feel. The EZ Mode displays frequently-accessed setup info, while the Advanced Mode is for experienced performance enthusiasts that demand far more intricate system settings.
Above screenshots on the new uEFI BIOS feature, and yes it is as impressive as it looks. So yes, the uEFI BIOS is really handy to use and easy to navigate. next to that it makes common functions really fail proof, features like flashing a BIOS is done in a jiffy and all variables can be managed and monitored really easy. A massive improvement over the classic BIOS alright. We'll see a lot of ODMs make the move to uEFI BIOSes this year.
