OK this is probably a common question. I've looked in the
mini FAQ and I now have more Qs than As.

Anyway. If you are compiling using DJGPP with DPMI is
it still possible to write directly to the screen, using
address 0xD0000000 I mean?

If it is still possible is it recommended?

If it is not possible, how does GRX do it?

I belive you have to be in DPMI mode to get the graphics
working in a DOS box in Windows, is this right?

You see I want to write my own fast assembler routines
to access the screen for a game I am writing. I do like
the idea of writing in 32 bit flat memory and DJGPP seems
ideal.

Hope you can help. Thanks.
