I have an Intel NUC D54250WYKH with Windows 8.1 Enterprise. Most of the drivers self installed but I have 2 drivers missing. In the device manager under "Other Devices" there is an "SM Bus Controller on PCI bus 0, device 31, function 3" and "Unknown Device on PCI standard ISA bridge" indicating a warning due to missing drivers. I have downloaded the "Driver Bundle" but the only thing that appears to install is the audio driver. It is possible that one of the missing items is the IR sensor which I don't see a driver for. I may have installed Windows in the wrong order since I installed the OS and immediately updated it without first installing drivers.
Does anyone know what these missing drivers are?
