I think he's right.  Only Windows up to ver 2 would run on a plain
8086/8088.  Windows 3.x did require a minimum of a 286 in standard
mode.

Does Linux/x86 really need to virtualize a 386, 486 or Pentium?
Isn't it already running on a 386, 486 or Pentium?  <g>
 
DOSEMU need not only emulate the CPU though - in particular it needs
to emulate the software and hardware environment of an MS-DOS machine.
