Bus Hierarchy

The following figure is representative of the PCI Bus hierarchies for the
2 Slot CardBus to PCI Expansion System. This figure pictorially conveys
the overall PCI bus topology of the system.
In general, we do not know what the actual Bus numbers are. We only
know how they increment starting from the CardBus card.
The key point in the figure of the 2 slot topology is that the connecting
cable between the CardBus card and the 2 slot backplane is actually a
PCI bus itself. This is represented in the Windows Device Manager as
shown below:
NOTE
All PCI cards installed in the PCI Expansion chassis will appear on
the Third PCI Bus behind the PCI Bus that the CardBus card is
installed on. If you need to know the actual Bus number, right-click
on the Bus and select Properties.
