The code in sys/i386/pcibus.c is used to search for all the host-pci bridges so that nexus can grow toplevel pcib instances for each one. The stuff in pcisupport is just informational. In fact, I'm planning to chop it out soon since I want to be able to attach an AGP driver to some of those devices. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
