Hi (again),
I might as well ask one more thing before I go offline.
Is the linear adress that I'll get from the "Physical Address Mapping" DPMI
function 800h, ready to use as an offset. or do I have to convert that
linear address into something else before i may use it as an offset?

the reason why I ask this is because in a tutorial about "vbe and linear
frame buffering", function 800h was used to Map the linear frame videobuffer
or something. But when I try to do that, nothing happends...  (I'm doing it
in nasm)

If I have a physical address in bx:cx, and then call the dpmi interrupt
function 800h, I should get a new linear adress in bx:cx, acording to the
dpmi refferences I've read. But nothing happends at all. Do I need to
upgrade the DPMI version (current ver: 0.9) or what?
