SMBus controller not detected properly


Windows* does not recognize the SMBus controller.
Device Manager shows a yellow question mark for the SMBus controller.
Device Manager lists the SMBus controller under Other Devices.

SMBus is the System Management Bus defined by Intel in 1995. It is used in personal computers and servers for low-speed system management communications. An SMBus controller is integrated into most Intel® chipsets.


Download and run the Intel® Chipset Software Installation Utility. This will install the chipset INF files so that Windows* properly recognizes the chipset’s built-in SMBus controller.
