Here are a few current bugs and mysteries: As it turns out, I lied slightly. A PCI bus driver for the U3 bridge can be found at http://banshee.uchicago.edu/~nwhitehorn/cpcht.tgz. Interrupt delivery and setup is still broken, so the boot process hangs while trying to probe USB, but the whole PCI bus can be probed now. Also, I/O port allocation is turned off. The PCI buses in my iMac G5 don't seem to have a space for I/O ports, or at least not one that I can find, and I can't locate the CPC925 manual. Now, back to real work... -Nathan
