### EDK II Image Description File (.IDF) File Format Specification #### 1. Introduction ##### 1.1 Related Information The **EDK II Image Description File (.IDF) File Format Specification** is a document that outlines the structure and content of IDF files used in the EDK II framework. The EDK II (or UEFI Development Kit II) is a set of open-source tools and components for developing firmware based on the Unified Extensible Firmware Interface (UEFI) specification. This specification provides guidance on how to create IDF files, which are crucial for configuring build processes within the EDK II environment. ##### 1.2 Terms **EDK II**: Stands for UEFI Development Kit II, an open-source project for developing UEFI-based firmware. **IDF (Image Description File)**: A file format used by EDK II to describe firmware images, including their dependencies and build configurations. **UEFI**: The Unified Extensible Firmware Interface, a specification that defines a software interface between an operating system and platform firmware. ##### 1.3 Conventions Used in this Document - **Bold**: Used for keywords and terms that are defined or emphasized. - **Italic**: Used for file names, paths, and other code elements. - **Monospace**: Used for commands, file names, and other elements that need to be typed as they appear. #### 2. HII Image Packs ##### 2.1 Definitions **HII (Hardware Information Interface)**: A technology provided by EDK II for handling user interface and configuration data during the firmware build process. HII Image Packs are collections of data and definitions used to describe UI elements and configuration options for firmware. - **Definition Pack**: Contains the metadata and definitions needed to construct the UI and configuration settings. - **Data Pack**: Contains the actual data that populates the UI and configuration settings. ##### 2.2 Example Here's a simplified example of how an HII Image Pack might be structured: - **Definition Pack**: `HiiPack.dsc` - Defines the UI layout and configuration options. - **Data Pack**: `HiiData.dsc` - Provides the data to populate the UI and configuration settings. ### Revision 1.00 This document represents the first official release of the EDK II Image Description File (.IDF) File Format Specification. It was released on April 2017 and is version 1.00. The purpose of this document is to provide a clear and detailed description of the IDF file format, which is essential for developers who work with the EDK II framework. The IDF file format is used to describe firmware images, including their dependencies and build configurations. #### Acknowledgements The document acknowledges the contributions made by the Tianocore project, which is responsible for maintaining and developing the EDK II framework. The document also includes a redistribution license, which allows the document to be used freely under certain conditions. These conditions include retaining the copyright notice and disclaimer in both source and compiled forms. #### Redistribution and Use The document specifies the following conditions for redistribution and use: 1. **Source Code (Original Document Form):** Redistributions must retain the copyright notice, list of conditions, and the disclaimer as the first lines of the file unmodified. 2. **Compiled Forms (Converted to PDF, epub, HTML, etc.):** Redistributions must reproduce the copyright notice, list of conditions, and the disclaimer in the documentation and/or other materials provided with the distribution. #### Disclaimer The document includes a disclaimer stating that the documentation is provided "as is" without any express or implied warranties, including the implied warranties of merchantability and fitness for a particular purpose.

It provides a comprehensive guide to creating and using IDF files, which are essential for building firmware images. By adhering to the conventions and guidelines outlined in this document, developers can ensure that their IDF files are well-structured and compatible with the EDK II build system.
