  • Patent number: 11507421
    Abstract: Information handling systems (IHSs) and methods are provided herein to allocate Peripheral Component Interconnect Express (PCIe) bus resources to a plurality of PCIe slots according to various PCIe bus resource allocation option settings. At least one host processor is included within the IHS for executing program instructions to detect a PCIe bus allocation option setting selected from a plurality of options provided in a boot firmware setup menu; determine if the PCIe bus allocation option setting has changed since the IHS was last booted; and allocate PCIe bus resources to the plurality of PCIe slots according to the detected PCIe bus allocation option setting. The plurality of options provided in the boot firmware setup menu include at least an auto detect option, which when selected, enables the at least one host processor to automatically detect unused PCIe slots and reallocate PCIe bus resources to used PCIe slots.

  • Patent number: 11301413
    Abstract: An information handling system may include at least one processor; a slot configured to receive an information handling resource and couple the information handling resource to a communications bus of the information handling system; and a computer-readable medium having instructions thereon that are executable by the at least one processor. The instructions may be executable for determining logical states for a plurality of pins of the slot; based on the determined logical states, determining a communications width associated with an information handling resource received in the slot; and setting a bifurcation variable associated with the slot based on the determined communications width.
