How to implement PCI Express into my project.

RFX,

I contact altera's support. But it didn't help. I send to them another especific question about our problem. I'm waiting for the answer. I'll send you new informations as soon as altera answers me.

I've opened reference design files to compare reference's pci code (that code generated by pci compiler) with mine code. It's exactly the same thing (it changes just some BARs memory size). Device ID, Vendor ID and the others fields of PCI registers are equal to reference's code.

Do you know if , when BIOS start to recognize PCI devices plugged on the computer, is there a transaction that localside of PCI megafuntion has to deal with it?

I'm saying this because I just implement in my project control functions to deal with read and write PCI transactions. Maybe we have to make something else.
