There's ExFAT, you might like to take a look at that. Supposedly has 64
bit structures designed specifically for very large file systems.

A very clever developer could write a "shim" to fit between the (U)EFI
firmware and FreeDOS. It certainly is quite possible to do that.

UEFI allows the loading of images, so you can just boot the shim off the
FreeDOS partition, have it set up an emulated BIOS in very high memory,
then boot FreeDOS itself.
