Get the DPMI spec, run under DPMI.  It provides services to do this, and
this is the way it will need to be done under V2.  If you don't have a
DPMI provider around, get CWSDPMI from ftp.neosoft.com:/pub/users/s/sandmann

Remember GO32 disappears very soon, it's a dead product, don't program for
it's quirks!
