Where can I get the SM Bus controller driver for my Gateway computer?

by on August 7, 2009

Q: I have a Gateway mx6445 laptop, which I purchased used so I do not have any original disks to it. I had to reinstall my OS, Windows XP mce. I was able to download drivers from gateway’s support site; however, now it says it needs SM Bus controller and I cannot seem to locate a usable driver. My graphics card is integrated and is ATI’s Radeon Xpress 200M. I downloaded that driver from gateway buy why wasn’t the SM Bus driver included? Please help! Where can I get this driver?
