Unknown "PCI Device" in task manager...

[InorganicMatter]

Built three computers, each one is showing a "PCI Device" and a "PCI Serial Port" in the device manager. The motherboard is an Intel D945GTP, I installed all the drivers for it on all three computers, yet they all show this mysterious device. There is a serial port on the back of the computer, and I don't see a COM port in the device manager, but shouldn't those drivers have come with the Chipset drivers?
