This branch represents the UEFI bootloader used by Sync.
It tries to set a nice video mode, then gets the date and time, then finds, packs and loads the kernel, giving the information gathered to it.
A .sln project is provided for convenience. The Windows SDK is required to compile using it, but it also works with gcc and llvm.
The best way to compile currently is using the compile.sh script provided.
It's far easier to compile on Windows, but ¯\_(?)_/¯
