(MM stands for M odule M anager) is the unofficial industry standard tool for viewing, extracting, replacing, and deleting modules inside UEFI BIOS firmware images ( .ROM , .BIN , .CAP , .FD ).
Always save a pristine, working copy of your motherboard's current BIOS using a hardware programmer (like a CH341A) or an official motherboard backup utility before flashing any modified firmware.
Open the newly created file in (from GitHub) to double-check that the file system structure parses correctly without parsing errors or nested volume corruptions. Crucial Safety Rules and Troubleshooting
: Repositories often act as wikis, providing step-by-step instructions on which version of MMTool (e.g., v4.50 or v5.02) is required for specific motherboard generations. mmtool github
: Always have a hardware programmer and a backup of the original full BIOS dump (not just the update file from the vendor website). Updates files are often trimmed and lack the descriptor and ME regions.

: Before flashing any modified BIOS created via MMTool or UEFITool, dump your current working BIOS using a hardware programmer (like a CH341A) or software tools like Intel FPT or AFUDOS.
: Use MMTool only for very old (pre-2015) AMI UEFI or when you need the specific Insert Compressed algorithm that some fork preserves. For everything else, clone LongSoft/UEFITool-NE .
