Get CSMWrap from here: https://github.com/FlyGoat/CSMWrap CSMWrap is one of the most exciting developments in retrocomputing right now - a complete x86 BIOS packed into a single .EFI file that lets you run legacy operating systems on modern UEFI hardware. No emulation. Just a clever SeaBIOS wrapper that takes over from your UEFI firmware without touching anything on it. Why does this matter? Well... CSM (Compatibility Support Module) is disappearing - already gone on LGA 1851, and eventually AM6 will follow. CSMWrap fills that gap, and unlike a fixed firmware implementation, it can be updated and expanded over time.
