MMTool is a BIOS/UEFI utility from AMI.
It stands for Module Management Tool and lets users manage firmware modules inside an Aptio ROM image.
You can use it to insert, delete, extract modules or Option ROMs, and view all module information — even after the ROM image has already been built.
Key features include working with compressed modules, creating reports, modifying the firmware without rebuilding the entire ROM, and supporting PEI/DXE modules plus command line options.
It works on x64, x86, and ARM architectures.
