Hi,
Can you right click on the SM Bus controller error (and any other errors) in the device manager>Properties>Details Tab
Post the DEV/VEN numbers you find under Device Instance ID
I just want to confirm the following befroe you download the SOUTH BRIDGE driver (SM Bus Controller)
According to the specs I could find you have a Radeon Xpress 200 chipset
RS482
The SM Bus controller is the southbridge driver:
