<P> The Unified Extensible Firmware Interface ( UEFI ) is a specification that defines a software interface between an operating system and platform firmware . UEFI replaces the Basic Input / Output System ( BIOS ) firmware interface originally present in all IBM PC - compatible personal computers , with most UEFI firmware implementations providing legacy support for BIOS services . UEFI can support remote diagnostics and repair of computers , even with no operating system installed . The user can enter a setup utility by quickly pressing the manufacturer 's specific setup key at an early moment when the computer starts up . The most common such keys are Delete , F2 , F12 , and Esc . </P>
