If you have used a PC during the last three decades or so, you should be familiar with the PC’s Basic Input / Outpit System, or BIOS. The fact that it has been around for so long should also be all the indication you need that it has outlived its usefulness. UEFI is poised to replace it, and take our PC experience to the next level.

The BIOS provides the core functionality for the motherboard itself that enables the hardware to function, and provides the jumpstart for the system before the actual operating system boot process begins. It is essentially the operating system for the motherboard, and your operating system of choice runs on top of it.
