Agreed. (Like I'd dare to differ with Fred.)

My 2¢'s worth is just: for an XT, if you want to fit a CF card or
something, try DR-DOS 3.41. It's out there in various places. RAM
usage as small as MS-DOS 3.3 but offers most of the benefits of MS-DOS
4 and some of MS-DOS 5 (both of which take a *lot* more RAM on an
XT-class machine.)
