 The main problem with the graphics modes in the PC is that
either le resolution is too low (320*200) or it is too slow
(640*480) and demand too much memory.
 Is it possible to use some intermediate mode, like 400*256,
400*320, 512*320, 512*384, or something like that ?

 Another question:
 How come the VGA and following cards used this stupid
bit planes system ? When you want to modify a 256 color
pixel, you must access 8 times the same adress, with
IO manipulations between ! It's very slow, and it's
pointless.
