Got a question about Mac video cards. Ok, my 6500 has a built-in ATI Mach64 Rage II w/ 2MB video memory. I tried putting a Radius card in, and well, that screwed with a lot of things in YDL. Considering it only has 2MB of memory, I can't bypass 800x600 resolution. I read where I could upgrade the video with another ATI product. Does this mean it "HAS" to be an ATI product? I guess it doesn't really matter if it does. Also, how would I disable the built-in ATI since There doesn't seem to be any jumpers for it?
