: A tool that controls the MMTool GUI to automate the extraction of all modules from an AMI EFI ROM, which is useful for comparing ROM files.
: This happens if the ROM file is encapsulated in an extra security capsule (common with .CAP files from ASUS). You must use a tool or script to strip the capsule header before processing it with MMTool. mmtool github
Most developers have abandoned MMTool for UEFITool. If you find an old mmtool repo that hasn't been updated in 5+ years, switch to UEFITool.

Clone the repository: git clone git://github.com/hrsmnr/MMTool.git .
MMTool's documentation, usually found in the repository's wiki or documentation folder, provides comprehensive guides on installation, usage, and development. You must use a tool or script to
- Open MMTool, click Load Image , and select your BIOS file. Navigate to the appropriate tab ( Insert , Replace , Extract ). You may need to identify a reference module (like PciBus ) to ensure the insertion is placed in the correct volume. Then, browse for your module file and click Insert or Replace .
A typical CLI template (found in several GitHub gists):
UEFI images are structured as a hierarchy of , containing Files , which contain Sections , which contain compressed data. Navigating this manually is impossible without a map. MMTool provides that map.
