I have the ATI Radeon X1600 256mb card on my MacBook Pro. I'm currently using the Boot Camp ATI drivers but when I try to update them with the new 7.1 Catalyst drivers, I get an error saying my card is not supported and then another error saying I have to make sure I have standard VGA drivers installed. What does all this mean? Can we not update the drivers on Boot Camp? It says in the specs for Catalyst that it supports my card.
