It also describes the procedures for configuring the system to install UEFI aware Operating Systems that take advantage of the new features available in the UEFI standard. What is UEFI The Unified Extensible Firmware Interface (UEFI) specification describes an interface between an Operating System and the system firmware. UEFI firmware replaces the basic input/output system (BIOS), which has been in place for x86 personal computers and servers for decades, and provides advantages not possible with the older technology. At system power-on, BIOS identifies and initializes the system’s hardware devices (such as the hard disk, video adapter, keyboard, and mouse). BIOS then loads the operating system from local storage (floppy, hard disk, CD-ROM, USB) or network, and passes control to it. BIOS is specific to the Intel x86 processor architecture, and it relies on the 16-bit real mode interface supported by x86 processors. UEFI defines a similar interface that operates between the
