Bus Hierarchy

The following figures are representative of the PCI Bus hierarchies for

the 4 Slot CardBus and PCI to PCI Expansion Systems. These figures

pictorially conveys the overall PCI bus topology of the system.

The key point in the following figure of the 4 Slot Topology is the

connecting cable between the Host Interface Card and the Expansion

Interface is actually a PCI bus itself.

In general, we do not know what the actual Bus numbers are. We only

know how they increment starting from the MAGMA PCI Host Interface.

4 Slot Topology

NOTE

All PCI cards installed in the 4 Slot PCI to PCI Expansion Systems wil

appear on PCI Bus 2. In Apple G4s, Bus 0 is internal; so all Busses

are incremented by 1. All PCI Cards installed in the 4 Slot CardBus

PCI Expansion System will appear on Bus 3. In laptop computers, the

CardBus slot is Bus 1, so all Busses are incremented by 1.
