Authenticated Code Module
Advanced Configuration and Power Interface
Intel Binary Configuration Tool
Boot Firmware Volume
The EDK II package a developer creates to port the Minimum Platform for their motherboard or family of motherboards
Boot Setting File
An executable binary. Typically UEFI defined, e.g. PEIM, DXE driver, SMM driver, or UEFI application. Also used to refer to other system binaries. Not appropriate for statically linked libraries.
Driver execution environment. Role is to load drivers for system devices. Finds and executes boot code. After OS loads, it handles OS to UEFI calls.

Field Replaceable Unit, the minimal silicon that can be added or removed from a system, e.g.
an SoC, a MCP, a standalone processor or PCH.
Intel® Firmware Support Package
A platform implementation that includes the minimal features, as well as some number of advanced features. (Stage I-VII). Note: most advanced features may not be described in this document.
Firmware Volume, a UEFI Forum defined firmware storage container
General Purpose Input/Output
Globally Unique Identifier(s)
Hand Off Blocks(s)
Any Module that contains both EDKII compliant wrapper code, and non EDK payloads (e.g., CSM-bin or FSP-bin)
Initial Boot Block
Integrated Firmware Image, includes things like UEFI firmware, microcode, microcontroller and firmware, configuration data.
Initial Program Load
Microsoft Macro Assembler
A platform implementation that only includes the minimal features. (Stage I-VII)
The EDK II package that contains common elements of the platform architecture.
Typically any EDK II independently buildable item, includes static libraries and executables.
Memory Overwrite Request. See Trusted Computing Group documentation.
Memory Type Range Register
All modules build with only EDKII compliant source code, and no non-EDK payloads (e.g., CSM-bin, LegacyOpRom, or FSP-bin)
Non-Volatile Random Access Memory
OEM Boot Block
Platform Configuration Database
Pre EFI Initialization. Role is to initialize memory, and also initialize enough of the system to run DXE.
