Issue:

• 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.

Background:

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.

Solution:

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.

Operating System:

Windows* 98, Windows* 98 SE, Windows* 2000, Windows* Me, Windows* XP Professional, Windows* XP Home Edition, Windows* XP Tablet PC Edition, Windows Server* 2003, Windows* XP Media Center Edition, Windows* 2000 Server, Windows* 2000 Advanced Server
