IBM PC-DOS (Personal Computer Disk Operating System) is an operating system for x86 based personal computers developed by Microsoft and IBM (later by IBM exclusively). Up to version 5.00, PC-DOS (then called IBM DOS) was just a rebranded IBM OEM version of MS-DOS, though IBM used their own versioning system. However, with version 5.00, IBM decided to continue PC-DOS development without Microsoft and renamed the product to IBM PC-DOS. Therefor, version 5.00 and later are IBM's own creation independent of MS-DOS. The first version released was version 1.00 and the last version was PC-DOS 2000, an updated release of PC-DOS 7.0.
