First, please refrain from sending more than one copy... and second, to achieve
 higher video modes, you can eaither switch to VESA stuff, or use unchained VGA
 video modes.  If you do a web search, there is a fair number of results.    

I would recomend downloading Allegro 2.  Then you can either use that, or see
 how they use unchained VGA and VESA...
