Platform Initialization Specification

Platform Initialization Specification

The Platform Initialization Specification (PI Specification) is a specification published by The Unified EFI Forum that describes the internal interfaces between different parts of computer platform firmware; this allows for more interoperability between firmware components from different sources. This specification is normally, but not by requirement, used in conjunction with the EFI specification.

Current Version

UEFI Platform Initialization Specification version 1.1, published February 22, 2008
