DOS 1.x (1981) had no explicit memory management support. It was designed to run primarily on machines with 64K RAM or less, or not too much more (the original PC could not have more than 64K RAM on the system board, although RAM expansion boards did exist).

As a postscript, we ought to ask if the same reasoning applies to rationals; if it does, that would contradict our earlier argument that rational numbers can only have a handful of 2-good solutions. To show that there is no contradiction, note that in the rational case, s can conceivably reach zero (i.e., a / b can be an exact approximation). Next, rewrite r as p / q in the left-hand portion of the earlier inequality:
