Unified Extensible Firmware Interface in Operating System

Abstract

The BIOS is very important part in the Motherboard because it’s the first IC work and check all the internal devices and the external devices , but the problem is the BIOS is old technology its borne in 1975 and now we are in 2016 we can use the BIOS only anymore because the BIOS depend on 16 bit and now we use 32 and 64 bit operating system and the BIOS can’t support more than 2.2 T bytes size of the hard disk and cant divide the hard disk more than 4 partition  .So we need to use new technology it’s called Unified Extensible Firmware Interface (UEFI) it’s just firmware support the BIOS to make it work more efficient .

Our report highlight on the UEFI technology and explain the method and the structure of the work and the phases for the operating system booting in UEFI mode.
