Cyclone IV GX FPGA Development board not recognised by PC when in PCIe slot

Just received a Cyclone IV GX FPGA Development kit and downloaded the demo c4gx_PCIe_gen1_x1.sof to it but when the PC boots up id does not recognise the board. I am unable to install a driver for it...

PCI and PCIe devices are enumerated at power-on by the BIOS. This means that if you download the .sof to the board, you need to warm-reboot the PC containing the board. This is generally not an issue if your PCIe machine is not your development machine :)

Cheers,
