: Get the DPMI spec, run under DPMI.  It provides services to do this, and

Actually, I'm glad someone told me about adding 0xe0000000 to the offset to
be able to access any random address.. This works just fine!

Why? The version I'm using right now, 1.13m4, I think, does everything I need
it to do.. So what if the later versions don't do what I'm doing now, I'll
just stay with this one. Its only if this version doesn't support an
important function that I'll consider moving to another one..
