Fix Missing SM Bus Controller driver for MSI FM2-A55M-E33 AMD Motherboard (MS-7721)
For years I used a MSI FM2-A55M-E33 in my work computer at my home office. From the first time I started the machine and installed drivers from MSIās website I was always missing the āSM Bus Controllerā driver. Everything seemed to work fine so I just ignored it for the few years I used that motherboard.
However, I recently upgraded my work computer to a different motherboard and put the old MSI FM2-A55M-E33 into my media server. The media server still runs Windows 7, but again the SM Bus Controller driver was missing just as when I ran Windows 10 on the motherboard. Generally, I only get drivers for devices from the device manufacturerās website but I decided to google this missing SM Bus Controller driver issue and see what I could find.
Fix Missing SM Bus Controller driver for MSI FM2-A55M-E33
So whatās the solution to a missing SM Bus Controller driver on a MSI FM2-A55M-E33 motherboard? It turns out itās technically just a Windows Driver to be used on all newer AMD chipsets that for some reason isnāt offered from the MSI website. Perhaps Windows Update used to install it, Iām not sure, but itās called āAdvanced Micro Devices, Inc driver update for AMD SMBusā and can be found for various Windows versions here: https://www.catalog.update.microsoft.com/Search.aspx?q=amd+smbus
Apparently missing āBus Controllerā drivers happen with Intel based chipsets as well, and the fix for that is an Intel install called āIntel INF Utilityā that lets Windows Update find the correct driver: https://downloadcenter.intel.com/download/28182/Chipset-INF-Utility?product=1145
