Hello.

I use DOS 6.2 with the EMM386.EXE extended/expanded driver which comes 
with it. Somewhere in djgpp documentation it says that if I disable 
expanded memory support (by giving the noems flag to EMM386) I will get 
go32 running in DPMI mode. however, typing go32 at the prompt still 
reports VCPI! Comments?

And, what's the difference anyway? Is there any reason I should _prefer_ 
the VCPI mode? I have a very good reason to disable EMS: I save the upper 
memory space which would otherwise be reserved for the EMS frame, and I 
can load some of my TRS's there.

Thanks in advance for throwing some light on this mystery.
