A few questions about modifying VGA cards:


1) How can I cram 2 VGA cards into a PC, and have them independently
addressable? Because of the way DOS handles it's video address space,
only one card can reside in the video address space, but what if, on a
3/486 the other card could be given a different address space that
doesn't clash with the first, and could be addressed via protected mode
on the 3/486.


2) Any ideas on how to give the VGA card a flat video memory, rather
than a paged one?

3) Lastly, is it possible to speed up writes to the video address space?
Currently its quite slow, and I want to speed it up.


Any thanks much appreciated.
