This document describes Extensible Firmware Interface (EFI) support in Windows and provides guidance to firmware and system designers for firmware support and implementation requirements. Observation and adherence to these guidelines and requirements will help ensure proper functionality of Windows operating systems on UEFI-based platforms.
All guidelines and requirements that are described in this document apply to all supported platform architectures of Windows Server operating systems beginning with Windows Server 2003 and to all Windows client operating systems beginning with Windows Vista SP1 unless explicitly noted otherwise.
This document does not replace any existing firmware requirements (such as ACPI requirements), and the contents must be considered additional requirements for an EFI-based platform.
