ATI 1900 and new MP compability – apple supp give mixed answers

[Sean Oneil]

[Uli Plank] “A courageous collegue over here tested it today. It didn’t damage his computer, but it doesn’t work either. When you boot with the original card in the MacPro plus the X1900, the latter is not even seen by system profiler. If you try with only the X1900, the machine doesn’t boot.”

Don’t want to be sour grapes, but everyone should know that PCIe 2.0 cards & systems are forward and backward compatible. Intel, ATI, and Nvidia have designed these products to work with the older ones. The info is all over the internets. There’s no chance this would have damaged the card. That would be a crazy class action lawsuit waiting to happen.

So it looks like Apple is purposely blocking users from doing this. Clearly the new Mac Pro firmware is set not to recognize older cards. They could allow it if they wanted to. But they don’t. I guess it might make sense given their unique business model. But it also makes them assholes.
