Topic: 9652 on Mac G5 - Card isn't recognized

Hello there. I have a 9652 card (branded "Nuendo 96/52"). I cannot get it to work on a Mac G5. The computer behaves as though it can't see the card. Apple System Profiler does not see the card in the PCI slot. The RME mixer doesn't recognize it, and Nuendo cannot find it.

This card was tested and cleared for G5 use by RME tech support in the USA (back in 2005). It functions normally in a G3.

Any ideas?
