I plugged my Cyclone IV GX kit to my PCIe Expansion slot. lspci command is not listing my device. What should I do?

The reason I'm getting confused is because I see two clocks p and n described in the documentation and both of them are mapped to the IO. So right now at my top level of HDl I see two inputs. Does that mean I should input these two clocks into a module (io buffer) and use the single clock that comes out of this buffet?
