Sm Bus Controller missing driver.  

This is listed as not having a driver but I don't know what it is.

I got that on my XPS 420 on first try of W7 x64. I went to Intel website and downloaded what looks like more or less an All-in-One chipset driver package and installed and that Device Manager error went away.

I also have the XPS420 (intel chipset) and had the same error. I got the driver package and it took a couple of installs and reboots for it to stick. As a convenience, you can download that package here:

Just extract the files into the folder of your choice, then goto the device manager and update the driver. You have to tell it to manually locate the driver, just put in the drive/folder name where you unzipped the file. Like I mentioned, it took a couple of installs/reboots for the driver to "stick" to the smbus.

I hope this helps (tip my scales :) )

Thanks Joe and zrtom I am in vista at the moment but I will try the drivers later.

Worked for me as well !

For mine I went to Intels site and downloaded the chipset driver which resolved the issue.
