I'm getting a yellow question mark in my Device Manager for a PCI Device which has not yet been installed and I can't figure out what this is for.

When I switch to View/Devices by Connection, it appears under the Intel 82801 GR/GH/GHM (ICH7 Family) PCI Express Root Port - 27E0.

Can anyone tell what this is and whether I should be concerned about it?

My Intel Express Installer Disk shows that the Marvel Raid Utility is not installed. Could this be it? I don't think I need that since I am running Intel Matrix Raid.

I have already installed the Chipset Software Installation program and update.
