extensible Firmware Interface or EFI) is a personal computer system specification used to define the software interface between the operating system and the system firmware, as an alternative to the BIOS upgrade scheme. The Extensible Firmware Interface is responsible for the power-on self-test (POST), the connection operating system, and the interface that connects the operating system to the hardware.EFI was originally developed by Intel and is now
