Abstract: An information handling system uses one connector for both liquid and air cooling and detects the type of cooling system installed. That provides the ability to choose the correct thermal handling table based on the installed cooling system. To detect the type of cooling system installed, a thermal management controller sets a control signal supplied to the cooling system through the connector to a first control value and determines if a tachometer signal supplied by the cooling system to the thermal management controller through the connector indicates a first type of cooling system. If the first type of cooling system is not detected, the thermal management controller checks if the tachometer signal from the cooling system with the control signal set at the first control value, or alternatively at a second control value, indicates a second type of cooling system. If no cooling system is detected, an error condition exists.

Abstract: A method for configuring a peripheral bus of an information handling system performs, as part of a boot sequence, an initial configuration of a chipset setting pertaining to the bus based on a descriptor stored in a nonvolatile storage resource. After an operating system is loaded, a controller detects a peripheral device connecting to the bus and responds by performing a runtime configuration of the chipset setting based on capability information obtained from the peripheral device. The peripheral bus may comprise a USB pipe and a USB-C type connector, wherein the peripheral device is detected by a USB power delivery (PD) controller based on configuration channel (CC) pins of the USB-C connector. The PD controller may signal the chipset and send the device’s capability information to the chipset. The PD controller may assert a PMCALERT# signal of the chipset’s and send the capability information via a system management link (SMLink1).

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.

Abstract: Systems and methods for intelligent fan identification are described. In some embodiments, an Information Handling System (IHS) may include: an embedded controller (EC); and a memory coupled to the EC, the memory having program instructions stored thereon that, upon execution by the EC, cause the IHS to: detect a cooling fan configuration issue; determine that a number of cooling fans in the IHS has not changed between a previous configuration and a current configuration; and in response to the determination, abstain from identifying the cooling fan configuration issue as a cooling fan error.
