PCI System Management Bus Help
I have two ethernet cards, 1 for our home network (Realtek) and 1 for our internet (DLink). Changed internet provider from HiSpeed Firberoptic phone co. to cable company. Installed cable co. software. Rebooted comp. and Windows said wizard had found "unknown device" and "PCI System Management Bus". Now it wants the appropriate driver but I can't find them because I didn't install any new devices. Cable co. help desk don't know anything about computers. Don't even understand difference between their external modem and a hardware devide. They gave me # of tech co that charge a fortune to resolve these problems. Can anyone help?
