Re: Core audio driver

I don't have access to a G5 either. Not yet. I had a look at the G5 hardware specification. It mentions chips named U3H and K2 and a PCI USB controller connected to the K2 chip. Don't know if they are just code names for commercial chips. I thought that Apple was designing its own ASICs.

The U3H is the main system controller. It connects the CPU(s) to the memory system, AGP and the hyper transport bus. This is an Apple designed part that is fabbed at the same facility the 970 is (at least this was the case at WWDC 2K3). As for K2 I only know what is in the tech specs, so I can only assume it is also a custom part.

Failure is not an option. It is a privilege reserved for those who try.
