I was referring to the installation procedures. IBM OS/2 2.0 to 4.0

But it's still true if one refers to single user versus multiuser -
WinNT's got a lot of OS/2 and VMS in its history, and OS/2's got a lot
of IBM's MVS and related mainframe OS knowledge in its background, but
they're not native multiuser. You need to get add-ons to make them
truly multiuser. In that they are still MS/PC/DR DOS writ large.
(Which is ironical considering that there have been at least two
genuine multiuser DOS clones on the market that I know of, DR's
Multiuser DOS - not Concurrent DOS: that was a similar but different
product - and PCMOS.)

OS/2 and Windows (including WinNT 3.x) just
added a pretty-pretty interface. OS/2 was more sophisticated than
WinNT's because OS/2 expected to share the hard drive with some other
OS; Microsoft believed it had the computer to itself and is thus not
as sophisticated - but they're still MS/PC/DR DOS writ large.
I would disagree with this assessment. NT's VMS heritage has already
been discussed. I do not know the heritage of OS/2 but to call it DOS
is simply not true. (Among other things, OS/2 did an excellent job of
virtualizing dosboxes. We were developing PCMCIA drivers with OS/2 in
dosboxes. When one crashed, you simply opened up another and
continued.)
