The way the existing pci code handles this is to probe the bridge for its maximum bus number and make sure that every bus number in the range is probed. It requires knowledge of each type of bridge to get this right. To fix this we need documentation of the configuration registers of the bridges in this machine. -- Doug Rabson Mail: dfr@nlsystems.com Nonlinear Systems Ltd.
