I don't think that is the sort of MS-DOS that Shark8 was referring to. DPMI 
is precisely the kind of support stuff that you don't want on your bare 
machine (at least not if you are planning to write "all Ada").

You could in theory boot a 32-bit DOS executable with solely a small chunk 
of assembler code to set up protected mode, but that's hard to do (I could 
never get it to work, in large part because there is no way to find out why 
it didn't work).
