Extended Daisy-Chain Configuration

In this case, the bus labeled (Bus 6) is obviously further downstream

(hierarchically speaking) than the bus labeled (Bus 4). And, of course,

there is a caveat to all of this: the bus numbering depends on the

algorithm implemented by your BIOS or console firmware configuration

code. We have labeled everything here as if:

a) The BIOS or firmware runs a true "depth-first" search of

the PCI bus hierarchy

b) Your BIOS or firmware will actually deal with multiple

PPBs

Fan-Out

In a fan-out configuration, successive PCI expansion systems are

added to the PCI bus hierarchy at a "peer" level of other existing

expansion buses, thus adding "breadth" to the PCI bus hierarchy since

these buses will be at the same hierarchical level within the system

configuration.

Fan-Out Configuration

The PCI Local Bus in your host computer will typically be numbered as

"PCI Bus Zero". Each addition of a PPB to the bus hierarchy will add a

new bus level into the hierarchy. In the following discussion, higher PCI

Local Bus numbers are termed to be "downstream" of lower numbered
