EFI Firmware File System Specification v0.9

Overview

This specification defines the core code that is required for an implementation of the Firmware File System (FFS) of the Intel® Platform Innovation Framework for EFI (hereafter referred to as the “Framework”). This FFS specification does the following:

• Describes the basic components of the FFS
• Defines basic operations that may be performed with the FFS
• Provides code definitions for FFS-related data types and structures that are architecturally required by the Intel® Platform Innovation Framework for EFI Architecture Specification
• Provides pseudo code that describes methods for initializing the FFS and accessing file prior to the FFS being initialized

Target Audience

This document is intended for the following readers:

• Independent hardware vendors (IHVs) and original equipment manufacturers (OEMs) who will be implementing firmware components 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
