SM BUS CONTROLLER CONFUSION = Your Bad you did not install CHIPSET DRIVERS. This specific Device manager error Goes all the way back to WIN2000 and carries forward all the way to Server 2012. Server 2003 DRIVERS ARE XP DRIVERS. Server 2008 Drivers are VISTA/WIN7 Drivers Server 2012 Drivers are WIN8/WIN10 Drivers. 
I'm running Win 7 x64 Ultimate on a new PowerEdge T20, base model.  I had a license for Win 7 so I installed it.  The system disk is a RAID 5 array of 3 x 120 GB SSDs, and the 4th SATA port runs an HDD that provides additional internal backup. The thing works spectacularly well for its purpose as an SVN server - it all works - but I'm following up on a couple of small mysteries... In the Device Manager, I see two devices listed in the "Other devices" category where Windows apparently failed to find a driver: [IMAGE] Since I am successfully able to monitor things like motherboard temperatures, and also to read/write USB devices from both the USB2 and USB3 ports, this seems just academic. Should I seek drivers for these things, or just ignore this? -Noel
