I am trying to access the 320x200 mode in VGA directly, but from what
I read in my VGA reference book, there is only one page.  Even though 
there is enough memory for 4 pages.  Does anyone have any code that 
handles page swapping directly in this mode, ie display one page, and
directly write to the other. 

Please E-Mail me even though I have been reading this group for months,
there is no reason to waste any more bandwidth with this question, if
there are any excellent methods, I may summorize.

Thanks,
