I need the info about the graphics mode on the AT&T 6300 computer:
(1) The codes I need to send to the video IO port to initialize the screen
    into graphics mode .
(2) The Base address of the video ram.
(3) How to access each pixel given the address (x, y).
(4) The codes to get back to text mode.
By graphics mode, I mean the 640x400 hi res mode. (or 640x200)
I know how to do this for Hercules card on a PC.
Thanks in advance.
