I have recently purchased one P4080 PCIe board. I have tried to connect it to my mother board PCIe slot. The problem is, when the board is booting up it cannot detect any PCIe link up. It tries 10 times and each time it would fail, and after that it would proceed to the boot process. I also turn on the device when my host is already booted up. I know the board is working with 8x PCIe and my mother board has a 16x PCIe. I'm not sure if this is the problem or not. Does anyone have any clue what could be the problem?
