The Unified Extensible Firmware Interface (UEFI)
replaces the basic input/output system (BIOS),
which has enabled x86 personal computer and
server products for nearly 30 years, starting with
the IBM Personal Computer (PC) in 1981. UEFI
defines a standard interface between the
operating system, platform firmware, and external
devices and offers capabilities that far exceed
those of BIOS and improved effectiveness of
server development.
Intel® Corporation developed EFI in the mid
1990s to enable the Itanium® class of processors
without having to implement legacy processor
operating modes that are required by BIOS.
Later, the UEFI Forum Inc. was formed by Intel, IBM, Hewlett-Packard, Dell, Apple, and other
companies to turn EFI into a industry standard that is appropriate for broader use on other
architectures, including x86 and x64.
