: Version 3.26 is strictly for non-UEFI AMI BIOS. Attempting to use it on modern UEFI/Aptio files will typically result in errors or a failure to load the image.
Old Option ROMs (like the Intel RAID or AHCI ROM) often have bugs or performance issues. MMTool 3.26 allows you to extract the current ROM module, replace it with an updated one from a newer motherboard, and repack the BIOS. mmtool 326zip
MMTool (Module Manipulation Tool) is an official utility from American Megatrends (AMI) designed for engineers to manage the "modules" within a BIOS image. While AMI does not distribute it to the public, various versions have leaked onto enthusiast forums like Win-Raid and Bios-Mods over the decades. The Significance of Version 3.26 : Version 3
Another major project is updating the CPU Microcode to improve system stability or allow an older motherboard to recognize a newer CPU, a practice known as a "BIOS transplant". With 3.26, you can open the CPU Patch tab, delete outdated entries, and insert a new microcode update file. This is a delicate operation that can permanently brick a motherboard if done incorrectly.

Some BIOS versions include patched microcode that prevents BCLK overclocking on locked Intel CPUs. Using the tab in MMTool 3.26, you can remove the microcode module. The BIOS will then fall back to built-in microcode, potentially unlocking better overclocks (use with extreme caution).
