A: AMI released 64-bit versions (e.g., 4.50, 5.0), but they are not called "326zip." That specific archive is 32-bit.
The Definitive Guide to MMTool 3.26: The Essential Tool for Legacy BIOS Modification
MMTool 326zip: The Ultimate Guide to AMI BIOS/UEFI Editing For enthusiasts, motherboard modders, and IT professionals, modifying the Basic Input/Output System (BIOS) or Unified Extensible Firmware Interface (UEFI) is a necessary skill to unlock hidden features, update microcodes, or support newer hardware. One of the most critical tools in this ecosystem is , particularly version 3.26, often distributed in a mmtool 326zip file.
Update RAID ROMs, LAN PXE boot ROMs, or Video BIOS (VBIOS) modules. mmtool 326zip
Allows you to save a specific module from the BIOS image onto your local hard drive as a .bin or .rom file.
Used for changing BIOS settings defaults (unhiding menus). Conclusion
MMTool 3.26 provides a graphical user interface (GUI) to interact with the underlying firmware structure. Its primary functions include: 1. Extracting Modules A: AMI released 64-bit versions (e
Click the Replace button. Verify that the "Size in ROM" updates correctly and that the tool does not throw a "file size exceeds volume capacity" error.
Change the file type dropdown to "All Files ( . )" to locate your specific motherboard BIOS file.
One of the most popular uses of MMTool in recent years has been to add NVMe (Non-Volatile Memory Express) boot support to old AMI BIOSes that originally only supported SATA drives. The process involves downloading a generic "NVMeOpRom" module and injecting it into the ROM with MMTool 3.26. After opening the ROM, you would navigate to the Insert tab, browse for the NVMe module, and then insert it (often specifying a specific Volume and Vendor/Device ID). Update RAID ROMs, LAN PXE boot ROMs, or
, a modified BIOS may be rejected or result in a "brick" (non-booting system). Hardware Required
If a module is outdated or corrupted, MMTool allows users to swap it out. For example, you can replace an old SATA/RAID Option ROM with a newer version to improve storage compatibility or boot speeds. 3. Inserting New Modules
Updating CPU Microcode to support newer processors on old boards.
