In a related query, has anyone experienced any problems with mode X on
Oak Technologies VGA card?  I have retrieved, assembled/compiled
Abrash's mode X examples, and while these examples work flawlessly on
a Trident SVGA at work, at home on an Oak Technologies card, they will
not successfully enter mode X.

I don't have access to any back issues of DDJ to check on the text of
Abrash's articles.  Is a 256K VGA card enough to tweak into mode X?  
Thanks for any info.  Email if you feel this is too basic for the
bandwidth :).


Still a novice,
T.C.
