FreeDOS is actually derived from DRDOS, which in turn came from CPM/86, and then back to the original CPM on the 8080. Novell bought (Intergalactic) Digital Research, divested DRDOS to Caldera along with their part of the UNIX rights, and Caldera donated it to the Free Software community.
By the way, the original CPM was pretty much a re-write of Digital Equipment Corp. RT11, down to device naming, PIP and everything.
DOS stands for Disk Operating System
