No.  What Windows provides is a way to run several DOS or DPMI
programs in separate Virtual Machines.  But Windows doesn't let you
run several DPMI programs in _the same_ Virtual Machine.  To get a
useful multiprocessing, you need the latter, because separate VMs
cannot easily communicate to each other, so you have problems with
redirecting handles, IPC, and other goodies which are what
multiprocessing is normally used for.

DR-DOS is not Free Software.
