Abstract: A method and system for supporting multiple Peripheral Component Interconnect (PCI) local buses through a single PCI host bridge having multiple PCI interfaces within a data-processing system are disclosed. In accordance with the method and system of the present invention, a processor and a system memory are connected to a system bus. First and second PCI local buses are connected to the system bus through a PCI host bridge. The first and second PCI local buses have sets of in-line electronic switches, dividing the PCI local buses into PCI local bus segments supporting a plurality of PCI peripheral component slots. The sets of in-line electronic switches are open and closed in accordance with bus control logic within the PCI host bridge allowing up to fourteen PCI peripheral component slots to have access through a single PCI host bridge to the system bus.
