Unified Extensible Firmware Interface
In July 2005, Intel discontinued its development of the EFI specification at version 1.10, and gave it to the Unified EFI Forum, which has developed the specification as the Unified Extensible Firmware Interface (UEFI). The original EFI specification remains owned by Intel, which exclusively provides licenses for EFI-based products, but the UEFI specification is owned by the UEFI Forum.
