Specification Organization

The Platform Initialization Specification is divided into volumes to enable logical organization, future growth, and printing convenience. The current volumes are as follows:

• Volume I: Pre-EFI Initialization

• Volume II: Driver Execution Environment Core Interface

• Volume III: Shared Architectural Elements

• Volume IV: Management Mode Core Interface

• Volume V: Standards

Each volume should be viewed in relation to all other volumes, and readers are strongly encouraged to consult the entire specification when researching areas of interest. Recent versions of this specification are issued as a single document containing all five volumes, for easier searching of the complete content.
