linux driver for cyclone4 PCIE hard ip ?

. I have 'successfully' built a pcie hard ip system on a cyclone 4gx but when I try to talk to the board from a linux box, there seems to be no comms between my linux box and the board. The box had a driver for the previous version of PCIe (Pcie soft ip from PLDA) so I was hoping it will support this as well. Is it possible that I need another driver in order for my board to work? I remember that I had to install a windows driver from jungo for the demo board to be recognised by my PC. Is there a Linux version of that driver?
