Appendix B Need More Slots?
In this configuration, you have fewer “Toll Booths” (PCI Bridges) to pass
through; therefore there are fewer opportunities for concern.
For clarification, it is necessary to understand that the amount
of latency caused by any PCI Bridge (even those built into a 3
rd
Party PCI card or the computer motherboard itself) is negligible
(“nanoseconds”) and will not produce any visible effect on most
systems. It is only mentioned here because on a few rare
configurations which use some unique PCI cards with special
software drivers, the total number of PCI buses that the data
must pass through COULD make a difference. See
for more information if you suspect this could
be an issue with one of your specialty PCI cards.
Verify your configuration
Before you start installing your PCI cards

, you should confirm that
everything is in proper working order. Refer to
