Important: A PCI-X and a PCI adapter can be installed in slots on the same
bus. However, those two adapters will both operate in PCI mode.
In addition, if you have a PCI-X adapter installed, you cannot hot-add a PCI
adapter to the same bus. This is because with just the PCI-X adapter installed,
the bus is running in PCI-X mode, and you cannot hot-add a PCI adapter into
a bus that is in PCI-X mode.
Table 3-5 summarizes the supported adapter speeds. Take into account the
speed reductions when there are two adapters installed in a bus, as described
above.
