Dell studio 1737 sm bus controller driver

Where can I find and download the SM Bus Controller drivers for the Dell Studio 1737?

I ran across the same problem with not being able to locate the SM & ethernet controllers after reloading Windows Vista. Resolved the problem by extracting all the files on the Utilities and Drivers disc, not just the ones that had check marks for my system. On the CD, from the dropdown menu select Studio Laptop 1737, your operating system (32 bit, 64 bit etc) and All. Can not tell you which file sresolved the issue but it did. Hope this helps.
