I find that entry in the memory allocation list of my computer (Workstation -> Device Manager -> View -> Resource by Type). It takes up 256MB of RAM and I'm wondering what's it good for.

“intel 945g pci express” is your motherboard, but no idea what is port 2771. – harrymc Nov 17 '09 at 9:25

From this Intel document

Root Port: A PCI Express Port, on a Root Complex, that maps a portion of the PCI Express interconnect Hierarchy through an associated virtual PCI-PCI Bridge.

Root Complex: An entity that includes a Host Bridge and one or more Root Ports.

Yeah, some circular definitions going on here.
