Question What is EFI? (UEFI)

EFI is the acronym for Extensible Firmware Interface, a likely replacement to the current BIOS firmware most PC's use.

These provide a standard environment for booting an operating system and running pre-boot applications.

The UEFI specification was primarily intended for the next generation of IA architecture-based computers, and is an outgrowth of the "Intel® Boot Initiative" (IBI) program that began in 1998. Intel's original version of this specification was publicly named EFI ending with the EFI 1.10 version. In 2005 The Unified EFI Forum was formed as an industry-wide organization to promote adoption and continue the development of the EFI specification. Using the EFI 1.10 specification as the starting point, this industry group released the follow on specifications renamed Unified EFI. The current version of the UEFI Specification can be found at the UEFI web site.
