Hai people,

I tried finding out how to map PHISICAL memory (at a known address)
into my DJGPP2.0 application. What do I need to make a normal pointer
pointing to the right location. I looked into libc.inf and DPMI specs,
but there is everything about absolute, linear and virtual addresses.
I don't see the light here. Does anyone have a working example?
