Sabah Mohammed Mlkat Almutoki, Alaa Abd Ali Hade, Ahmed Fadhil Mohammed


This paper gives an overview of the (Unified Extensible Firmware Interface) and describes the capabilities and supports operating systems and refers to the interest rate offered in this area. UEFI is a new interface deal between operating systems and the hardware inside your computer. Since more than thirty years and we are dealing with a blue screen. BIOS is an IC 16-bit is available on the memory 1 megabyte. The control of all hardware in the computer and through which the preparation of these settings that appear at the beginning of the run. which It works on the examination of the pieces associated hardware to the computer and make sure it works well, but  show contains some the problems of security vulnerabilities and lack of sufficient flexibility in the adjustment and modernization. Recently with the development of technology they became working on more data processors than its predecessors, such as processors 32-bit and 64-bit the Intel creates a new innovation called (Unified Extensible Firmware Interface). which will address many of the problems related to the BIOS and these problems, velocities and with the size of the systems, overload of programs as well as the speed of the startup where the BIOS takes more than thirty seconds to startup and show the system but now does not need to this time as well as the most important problems in terms of security where a problem of breakthrough devices and access them with the beginning of the startup has been processed and also allows us the ease of movement in the choice of settings. UEFI resolves the place and there is no need to have the old BIOS.
