Actually, this is the cart before the horse.  OS/2 Warp 4.0 wasn't modified 
so that it only works with its "own" version of Windows.  OS/2 Warp 4.0 is 
the same as OS/2 Warp 3.0 was in this respect.  
It is Windows that has always had to be modified to work under OS/2 (because 
of DPMI server conflicts and suchlike).  The "with Windows" flavours of OS/2 
contain a full installation of the Windows kernel, with the modifications 
already applied.  The "without Windows" flavours of OS/2 contains just those 
parts necessary to change an existing copy of the Windows kernel so that it 
runs on OS/2.
