I need to write a program which will run on all the graphics cards in any
text mode.  My problem is that I dont know enough about the non-cga cards.

My program will read directly from video memory, so my concern is that the
video memory will be in different spots with the other cards. Can someone
tell me where the various text modes hide in memory.  Pointers to books and
articles on the differrent cards would help a lot too.
Thanks
