Actually IBM bought DOS from Microsoft, which sold it to IBM before it even 
existed. The story of Gates looking for QDOS after cutting the deal is well 
known. Both IBM and Microsoft had their fingers intertwined so much in those 
days that it's hard to say who developed DOS. In fact, the infamous DOS 4 was 
developed by IBM and then released by Microsoft, they were still joined at 
the hip then. By the time DOS 5 came out, they had parted ways.
IBM's DOS was probably never widely accepted because they did not enforce the 
same licencing scheme that Microsoft did.
I assume that you know that much of your OS/2 was written my Microsoft?
