Exactly right, Chicken mania. Just run the setup file and it will overwrite the existing intel driver files. If the new drivers cause any problems you'll find the option to "roll back" to the older drivers in Control Panel (Classic view)->System->Hardware->Device Manager. The chipset drivers should be listed under "System Devices" -- if you double click any entry there you'll get a 'Properties' dialog-box and under the 'Driver' tab you'll see buttons for "Roll back driver" or "Uninstall". The "Update driver" button here would only be used if you want Windows to check Microsoft's own driver library for a newer driver, but since you already have new drivers from Intel with it's own installer that button is irrelevant.
