Hmm...are you implying that there is another sort of DOS extender? If
you don't switch back to V86/Real mode, you can't use DOS, and if you
don't use DOS to do your I/O, you don't have a DOS extender anymore...

True - I wasn't trying to give an exhaustive list by any means. There
are also several more versions of UNIX and similar systems such as Hurd
(yes, after only 14 or so years of arguing, it's actually in beta
testing) SCO, Interactive, Coherent, the 386 version of Minix, and so
on.

Maybe so. Anybody who wants to try it is welcome to go right to work on
the project. OTOH, the Nobel committee might not agree with me as to
the value of the work involved...
Later,
Jerry.
