If you are updating CPU microcodes or upgrading OROM/EFI drivers, do not use MMTool manually. Instead, use , a script-based automation tool.

Aptio V firmware often nests firmware volumes inside other firmware volumes (sometimes up to 3 or 4 layers deep). MMTool’s parsing engine has strict limitations on how deeply nested these volumes can be. If a module resides inside a deeply compressed sub-volume, MMTool cannot re-compress or rebuild the tree correctly. 4. Size and Space Constraints

: Open the tool and use the Load Image button to select your motherboard's .ROM , .BIN , or .CAP BIOS file. mmtool+aptio+4500023
