I recently put together a new PC from scratch.  New case, new motherboard, new CPU, new RAM, new hard drives, new video card, etc...

I am running Windows 2000 Pro on this machine.

After installing the OS and all components, I am having a problem identifying a mysterious "Other device" in Device Manager.  Here are the clues:

PCI Device
Manufacturer: Unknown
Location: PCI bus 0, device 31, function 3
Input/output range: C800-C81F
IRQ: 3

I'm trying to get rid of the little yellow "?" mark that is appearing next to this device in Device Manager, however, I have no clue what it is.  There is no device driver installed, hence without knowing what this device is I don't know what device driver to select from.

Any idea what this is?

Unknown Devices
Description
Unknown Devices helps you find what those unknown devices in Device Manager really are.

By checking Device Manager for unknown devices and extracting information from it, this program attempts to figure out what the device is. You might not have to open your case or look up random numbers off of PCI cards to figure out what they are.

Program supports Win95, 98, 98se, Me, 2k, XP and 2003 but not NT. It also attempts to support future OSes.
It runs fine from a CD or floppy. It's free for per personal and (especially) business use

When I try to use Unknown Devices, a message pops up that the "Item list is out of bounds"

Can you tell me what that means?
