His mother had zip to do with it. MIcrosoft in 1980 was already a leading language manufacturer for microcomputers. CPM was the first choice of IBM, not MS-DOS.

His mother was sitting on the board of IBM when they went looking for a replacement for CPM. Gates didn't develope DOS,but bought it from the developer. Nothing wrong with that,and he is responsible for further developement of it.
