Modding older BIOS to support booting from NVMe drives.
It's crucial to understand that this process is not without significant risk: mmtool 326zip
The package remains a legendary tool in firmware modding circles—lightweight, fast, and effective for older AMI UEFI BIOS images (pre-2018). For enthusiasts reviving an LGA1155 or AM3+ system, it's still the go-to utility for adding NVMe support or tweaking hidden parameters.
