The FreeDOS folks have declared that they will never be supporting UEFI. That's a shame, since SO MUCH WORK has gone into the FreeDOS project over the years, and refusing to support UEFI means that it will ultimately be unusable. But then, they are a crusty old bunch. If they DO make FreeDOS run under UEFI -- I seem to recall that there's a UEFI/BIOS translation layer somewhere -- that would allow me to shift my priorities and work on native driver support instead. But, again, the FreeDOS folks have been VERY clear about... "Nope, never."
