DOSBox allows one to use vesa drivers, and it also can translate between a driver and your actual card, which almost always differs these days. A straight XP DOS window, which not everyone has, does not necessarily allow such behavior. Very few of the cards in the list are still in use at all. Even though I own a few, that is beside the point. XP doesn't run on the machines that those cards do run on.

(or so I hear). > Aggravated by the fact that you could not easily buy a spare HV flyback transformer for a computer monitor. With TV sets they could be had for $30-$60, usually. Ok, sometimes you had to pretend you were a TV repair pro and don a white coat, or send a friend to buy it. -- Regards, Joerg http://www.analogconsultants.com/ "gmail" domain blocked because of excessive spam.
