Insert, delete, extract, and replace DXE (Driver Execution Environment) and PEI (Pre-EFI Initialization) modules.

: It is specifically optimized for AMI UEFI BIOSes released prior to the Intel X99 chipset.

The crown jewel of the tool. This allows you to swap an existing module within the BIOS image with a modified or third-party module. Common use cases include: Mmtool Aptio 4.50.0023

A modern UEFI BIOS is not a single piece of monolithic software. Instead, it is an organized container holding hundreds of individual modules, drivers, and configuration files. MMTool provides a graphical user interface (GUI) to view this complex tree structure. It allows you to manipulate these individual modules without breaking the structural integrity or checksum of the entire ROM file. Why Version 4.50.0023 Matters

This error happens if you attempt to force an insertion into a volume reserved for strictly bootloader blocks or security variables. Ensure you are targeting the primary DXE volume. Insert, delete, extract, and replace DXE (Driver Execution

Removes unnecessary modules to free up space within tight firmware volumes. Step-by-Step: Injecting NVMe Support into an Older BIOS

MMTool (Module Management Tool) is a proprietary utility developed by AMI. It is designed to allow developers and manufacturers to manage the individual modules within a BIOS/UEFI binary image (.ROM or .CAP files). This allows you to swap an existing module

Aptio 4 BIOS chips typically have strict storage limits (often 4MB or 8MB total). If you attempt to insert a module and receive an "Out of Space" or "Size exceeds volume limit" error, you must free up room. This is safely achieved by deleting unneeded modules, such as network boot drivers (PXE) or secondary language strings, before attempting the insertion again. Flashing Security Measures

Works with various ROM image types including .rom , .bin , and .cap (though capsules often need to be "stripped" before editing). Pro-Tips for Success
