Overview

The Unified EFI Forum is a non-profit collaborative trade organization formed to promote and manage the UEFI standard. As an evolving standard, the UEFI specification is driven by contributions and support from member companies of the UEFI Forum.

The UEFI Forum board of directors include representatives from the following eleven leading companies:

AMD American Megatrends Inc. Apple Computer, Inc. Dell Hewlett Packard IBM Insyde Intel Lenovo Microsoft Phoenix Technologies

 

With support and innovation from all UEFI Forum member companies, work is being done continually to evolve the UEFI specification to meet industry needs.

FAQs

Q: What is UEFI?

A: UEFI (Unified Extensible Firmware Interface) will be a specification detailing an interface that helps hand off control of the system for the pre-boot environment (i.e.: after the system is powered on, but before the operating system starts) to an operating system, such as Windows* or Linux*. UEFI will provide a clean interface between operating systems and platform firmware at boot time, and will support an architecture-independent mechanism for initializing add-in cards.

Q: What is the relationship between EFI and UEFI?

A: The UEFI specification will be based on the EFI 1.10 specification published by Intel with corrections and changes managed by the Unified EFI Forum. Intel still hol ds the copyright on the EFI 1.10 specification, but has contributed it to the Forum so that the Forum can evolve it. There will not be any future versions of the EFI specification, but customers who license it can still use it under the terms of their license from Intel. The license to the Unified EFI Specification will come from the Forum, not from Intel.
