Stratix II GX configuration

I think the MAX II device on the Stratix II GX PCIe board has a special build of the PFL that requires you to push one of the buttons on the board to get programming stuff to work. There's some documentation in the PCIe-to-DDR example project that talks about programming the on-board flash. I believe it talks about having to push a button to get the MAX II's PFL to talk to the Quartus programmer.
