It deals mostly with the pci chip set that controls such things as the timing to the pci bus to processor and such.

PCI-to-PCI bridge chips extend I/O support capability by enabling motherboard designers to exceed the four-slot PCI bus limitation for PCI devices and option cards. Each PCI-to-PCI bridge chip added to the motherboard creates a new PCI bus to support additional PCI slots or devices. A PCI-to-PCI bridge also enables adapter card designers to increase overcome the single load limitation of the PCI Specification by providing an independent PCI bus on the adapter card, to which as many as nine devices can be added.

As with most hardware there is a software driver needed with it
if you need the location of the driver let me know, it is only needed for Intels newest chipsets such as the tx lx or gx or bx pci chipsets.
If you need more info then let me know.
