• Provides code definitions for services and functions that are architecturally required by the Intel® Platform Innovation Framework for EFI Architecture Specification
• Presents a set of backward-compatible extensions to the EFI 1.10 Specification
• Describes the machine preparation that is required for subsequent phases of firmware execution See Organization of the DXE CIS for more information.

Target Audience

This document is intended for the following readers:

• IHVs and OEMs who will be implementing DXE drivers that are stored in firmware volumes.
• BIOS developers, either those who create general-purpose BIOS and other firmware products or those who modify these products for use in Intel® architecture–based products.
