- Because MMTool is not officially distributed, you must find a copy online. Search for "MMTool [Your BIOS Version Here] download" or refer to community guides. Only download from trusted sources.
UEFITool is the gold standard for open-source UEFI manipulation. It visualizes the structure of any UEFI-compliant firmware image. The UEFITool variant allows visual exploration, while UEFIReplace and UEFIExtract allow command-line module manipulation perfect for automation scripts. UBU (UEFI BIOS Updater) Status: Script-based automation
The script inserts an NvmExpressDxe driver module into the CSMCORE or main volume of the BIOS file. 2. CPU Microcode Automation
The (Module Management Tool) is a proprietary utility used to view and modify AMI UEFI BIOS/firmware files. While the official tool is not hosted as an open-source project on GitHub, many open-source projects like ReBarUEFI and AMI BIOS Code Injection provide documentation, scripts, and automation wrappers for it. Core Functionality
: A utility on CyberShadow's GitHub that helps users automate the extraction of all ROM modules from an AMI BIOS file [11]. mmtool github
: Adding NvmExpressDxe modules to older BIOS files to allow legacy motherboards to boot from NVMe SSDs.
Risks and how to mitigate them
Because the official MMTool is proprietary, you won't find the "source code" for the official AMI version on GitHub. Instead, GitHub repositories usually fall into these categories: BIOS Modding Toolkits
Adds new drivers (like NVMe DXE drivers) to older motherboards. - Because MMTool is not officially distributed, you
What are you trying to achieve (e.g., NVMe boot, microcode update, ReBAR)?

For most BIOS modification tasks (like adding NVMe support), the process generally follows these steps:

The most prominent "MMTool" in tech circles is an official AMI (American Megatrends) utility used for BIOS surgery. On GitHub, you'll find auxiliary tools built to support or automate it:
