SM Bus Controller driver installation

Those are the hardware IDs for the SM Bus Controller. I have a Code 28 saying the drivers aren't installed and the yellow exclamation mark in the device manager. Any help on what I need to download? I believe I've downloaded most of the drivers for my service tag, but some of them didn't work (like the Broadcom card... however, windows was able to install their own drivers that work).
