Acquire the target BIOS file (usually a .ROM or .CAP extension).

Regardless of version, MMTool provides a consistent set of powerful features that remain at the heart of all BIOS editing workflows:
Think of a BIOS file as a cabinet filled with specialized drawers (modules). MMTool is the key that lets you open that cabinet, remove a drawer, replace it with a newer one, or add a completely new drawer for additional functionality. This capability is why the tool has become indispensable for hardware enthusiasts, system administrators, and even professional firmware developers.
The "CPU Patch" tab provides a specialized interface for managing the processor microcode updates stored within the BIOS. You can extract the existing microcode, replace it with a newer version (often to fix stability issues or security vulnerabilities), or add support for a newer processor model not originally supported by your motherboard.
