SM Bus controller and unknown device

I am seeing this in device manager as a question mark and went to the IBM site and tried to find the drivers to download but I am not sure what driver I would need to look for, as there is no such animal as SM Bus comntroller on the list. I tried to run there software installer as well to load all this automatically but this does not see any packages as well. I also cannot figure out what or how to know what driver is listed with a question marrk refered to as unknown device. How would I know what unknown device this may be?

Usually, this is taken care of when you install the motherboard chipset drivers.  Once they are properly installed, this error should go away.

where would I look for these drivers?
At the manufacturer's website (in your case, it sounds like IBM).
