-
- OS/2 acts as a DPMI server, so OS/2 provides the DPMI memory that
- things like Borland C++ need.

-
- I don't see why a 386 UNIX couldn't be set up to provide DPMI server
- services so that something like VP/ix could run things needing those
- services. Note, however, that this still wouldn't let you run Windows
- in anything other than Real mode (in other words, nothing newer than
- Windows 3.0 would work).
