Abstract
A PCI bus system for a computer provides a main board with one or more PCI slots mounted on the board, and with each PCI slot adapted to receive a PHI card. Each PCI slot includes a plurality of electrical contacts. A multiplexor is provided for each PCI slot, and each multiplexor has at least first and second sets of electrical inputs selectively connectable to a set of outputs connected to a first set of the electrical contacts on its respective PCI slot. A link controller is provided for each PCI slot, with each link controller mounted on the main board. A first plurality of electrical lines for each PCI slot connect the respective link controller to the first set of electrical inputs on the respective multiplexor. A PCI controller is mounted on the main board, with a second plurality of electrical lines connecting the PHI controller to the second set of electrical inputs on the multiplexor. Also provided are a third plurality of electrical lines connecting the PCI controller to each of a second set of electrical contacts on each PCI slot, wherein the contacts of the second set are different from the first set.
