Hi all, I got a Toshiba Satellite A100 PSAACK-VA104C. It had Vista on it, but I had some compatibility issues, so I installed XP. I've tracked almost all the drivers I need but I can't figure where to find a driver for the sm bus controller. I've got no audio until this is installed. Where do I go and what am I looking for? Toshiba's website is no good as the only drivers they provide for this model are Vista drivers.
