MMTool (Memory Map Tool) is a specialized software utility designed for working with BIOS firmware on motherboards. It is primarily used by advanced users and technicians to modify, read, and write BIOS memory chips.
The main features of MMTool include:
- Reading BIOS ROM files
- Modifying BIOS modules
- Updating microcode
- Extracting and inserting BIOS components
- BIOS chip identification
- Support for various ROM file formats
This tool is particularly popular among hardware enthusiasts and professionals who need to perform BIOS-level modifications. However, it should be used with caution as incorrect usage can potentially damage the motherboard or make it inoperable.
MMTool is often used in conjunction with other BIOS modification tools and is especially useful for tasks such as updating CPU microcode or modifying RAID ROM modules. The program requires technical knowledge and understanding of BIOS structure to be used effectively and safely.
