MMTool 4.50.0.23: The Ultimate Guide to Classic AMI UEFI BIOS Modding
Legacy motherboards (such as Intel Z77, Z87, or X79 systems) support NVMe drives as secondary storage but cannot natively read the drive's file system during the initial POST phase. By using MMTool 4.50.0.23, users inject modules like NvmExpressDxe_5.ffs directly into the firmware layout. This allows users to boot modern M.2 NVMe SSDs via PCIe adapter cards. MMTool method creates unusable bios, UEFITool OC issue. #98 mmtool 4.50.0.23
