Abstract: Systems and methods disclosed herein provide a novel solution for PCIe port bifurcation. Unlike conventional client systems, which rely on resistors, jumpers or DIP switches, the disclosed systems and methods enable PCIe ports to be configured in accordance with a plurality of user-selectable PCIe bifurcation settings provided within a boot setup menu. When an “Auto” setting is selected in the boot setup menu, the disclosed systems and methods enable PCIe ports to be: (a) configured in accordance with the bifurcation requirements of the PCIe adapter card(s) connected to the PCIe ports, and (b) automatically reconfigured when bifurcation requirements change. Unlike conventional server systems, which require the user to enter BIOS setup and manually change the PCIe bifurcation settings provided in the BIOS setup menu, the systems and methods disclosed herein enable PCIe ports to be automatically reconfigured, when bifurcation requirements change, without user intervention.
