Toshiba Satellite A215-S7411 AMD 64 Athlon X2 WinXP32 I wiped out Vista and went back to XP. I have almost everything straightened out except for two things listed in the device manager. "SM bus controller" and 3 listings of "Base system device" all with question marks and exclamation points. I did a search for the bus controller but ened up running in circles. Has anyone got a solution for this? Thanks.
