Newer version of the Quartus(12.0) is installed now and I am able to build the PCIe system.

But I am not able to communicate with the board. I am working on a linux machine, and lspci command shows no track of the altera board being connected.

The design currently under test is without reconfiguration reset logic and withX4 width. Would this be a problem?
