On advice from Intell a while back, I finally bought and got around to installing a Radeon 9600XT in my main Quicksilver. I did so by taping off pins 3 and 11, and using the "fingers" off an old PC ISA card to bring the ADC from the socket on the Quicksilver logic board to the tab on the Radeon card. Functionally, the card is fine. It drives my 17" Studio Display and and a 20" 1620x1050 LCD just fine. The USB ports on the Studio Display even work. The only quirk I find is that the power button on the display will no longer power up the computer. I'm not sure that I'm getting the full capabilities of the card, however. Under 10.5, system profiler IDs the card correctly but says that Core Image is "software" and Quartz Extreme is not supported. I'm also not getting the GUI "goodies" that usually come with these features, such as the translucent menu bar and the "ripples" when adding a widget to the dashboard. I tested the card in one of my MDDs before soldering the ADC jumper onto it, and all of these features worked correctly. Is there an extension or kext that I need to check for in the 10.5 install on my Quicksilver to enable these features? And, one other thing...is there an OS 9 driver for this card?
