I just installed a new Asus P4800 Deluxe mobo. All Drivers in Device Manager are correct and everything is running smooth except my SM Bus Controller. First question - what the heck is this> I would assume it has to do with my front side bus, but am not sure... Second question - how do I install the correct driver for this? Someone told me it is located on the OS install disc (Win XP Pro) so I tried to update the driver by steering it toward the install disc. It searched and searched and finally came back with a negative response. Third question - what are the implications of not having this driver updated. As far as I can see I have no probs. Computer is fast as heck and I am running HT and have my FSB set to 800 mhz. Anyone?
