IBM has the rights to use MS-DOS, and then does their own additions/alterations, and sells PC-DOS. Compaq, Zenith, and any other manufacturer also can buy MS-DOS from Miscrosoft, and alter it for their machine and sell it. Everyone but IBM still calls it MS-DOS. It wasn't until somewhere around MS-DOS 3.3 that Microsoft began selling DOS directly (i.e. not through OEMs), and you could buy a box that was strictly from Microsoft. My MS-DOS 4.01 box says "Only to be sold with a computer", or words to that effect. Some manufacturers (and most clones) do not provide DOS at all: you have to get generic MS-DOS (or "borrow" someone else's, as probably happened before generic DOS became available). Dave Halliwell Let's be careful in there!
