Where are you going to store the graphics buffer at (memory, hard drive, etc.) and will it be an exact copy of what you want to show up on the screen?

"program devices directly from pmode"
"i am useing c and dos"

So, are you using DPMI, or some other dos extender?  Regular DOS isn't pmode.  Perhaps you could tell us specifically what C compiler you are using.
