Navigate through the module list. To update a module, select it and choose "Replace". To add a new driver, navigate to the "Insert" tab.
Once you download MMTool from a trusted GitHub release, follow this workflow:
Since MMTool is a closed-source Windows application, the community on GitHub has built several tools to extend its capabilities or integrate it into modern workflows:
If you search for "MMTool" on GitHub, you will not find an official, open-source repository hosted by AMI. Because MMTool is proprietary leak-ware or licensed software, hosting the raw binary files ( .exe ) violates GitHub’s Terms of Service and copyright laws. mmtool github
In simple terms: Your BIOS is a container file. Inside that container are "Volumes," and inside those volumes are "Files" (drivers, applications, logos). MMTool allows you to:
Advanced users utilize MMTool alongside GitHub projects to perform low-level firmware manipulation:
Swap outdated components (like network Option ROMs or CPU Microcodes) with newer versions. Navigate through the module list
It allows for advanced, low-level modifications, such as code injection via Post ROM Theldus/AMI_BIOS_CodeInjection .
: Saving specific binary files (like Option ROMs or specific DXE drivers) from an existing BIOS file for analysis or porting.
Whether you're looking to add a modern M.2 SSD to a decade-old system or simply want the latest security patches, the GitHub community provides the tools and knowledge to make it happen safely. Once you download MMTool from a trusted GitHub
Even without an official GitHub presence, MMTool remains highly sought-after for several niche modifications:
⚠️ Modifying your BIOS can brick your motherboard. Always have a hardware programmer (like CH341A) and a backup.
Run the repository's main script (e.g., python mod_bios.py or ./insert_modules.bat ).
Check repository mmtool-cli-wrapper for a Python script that automates driver slipstreaming across 50+ BIOS files.
: Modders often use MMTool to "backport" NVMe driver modules into older UEFI BIOS that lack native support for booting from M.2 SSDs.
