(December 2014) </Td> </Tr> <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> <P> Intel developed the original Extensible Firmware Interface (EFI) specification . Some of the EFI's practices and data formats mirror those from Microsoft Windows . In 2005, UEFI deprecated EFI 1.10 (the final release of EFI). The Unified EFI Forum is the industry body that manages the UEFI specification . </P>
