Any PCIe example working on XP must support legacy interrupts. The PCIe core that is used in Altera's example presumably does; if I get time I'll have a look at the application note. You need to check your SOPC PCIe configuaration builder settings to see if this capability exists and, if it does, make sure its selected. The core that I used supported only msi so I had no choice but to move to Vista and W7 for development.

You can, of course, manually control the DMA registers and poll them to see if DMA is actually working in your design, without using/needing interrupts.

Kind regards
