Pardon me. I am lost here. What is the question?
Windows 311 was often sold with DOS 6.22 and worked well as it could.
And you could do a full install of Windows 3.11 on top of another DOS instead of only MS-DOS. ANd it would work as well as it could.
I recall this detail because at the time there was a serious issue about the MS business practice of promoting the idea that it was better with MS-DOS.
But in either case, MS-DOS or some other DOS, there was loose integration of the GUI and the DOS. That is, it did not require a pure binary equal of the MS product to work.
So hen, Windows 3.11 was DOS based in the sense that the DOS was the fundamental files system. The GUI had its own engine for graphics. So it was a super structure on top of DOS.
Why is the issue so important that we rant over any OS that is no longer a current product? Is there some great truth to be learned?
Curious minds need to know.
Why is it important to say ...
whether an OS was DOS based?
