HP DX2400 Microtower – Windows XP and VISTA SM Bus Controller not installed?

The HP dx2400 Microtower SM BUS Controller might show up on your device manager with a question mark ( “?”) indicating that the driver is not loaded. The driver you need is the chipset driver. It would be easier if it would say “Chipset”, instead of SM BUS Controller, but that is not how computers work; why simplify, right?
So, here the link to download the chipset driver for both XP and Vista/Windows 7


Good luck!
