What jumper? What setting is this jumper supposed to control? And is the jumper on the video card or on the motherboard?
Sorry for my english, not a jumper.
A piece of wire/cable
This is what I was talking about

Thanks. Just to be clear, you are referring to the PCIe extender in that picture? What is that white twistie-tie thing for, that's curving from the front of the PCIe slot to the back of it, and curves around two capacitors?
Looks like the twisty-tie is electrically connecting pin#81 of the B-side (2nd from bottom right in usual locking-clip-to-left orientation) to pin#1 of the A-side (top-left), and thus letting the motherboard know something is plugged in (without filling the whole x16 slot).
I'm basing this guess on the pinout information at:
http://pinouts.ru/Slots/pci_express_pinout.shtml...where it also says, "Add on card needs to have PRSNT#1 connected to one of PRSNT#2 depending what type of connector is in use.". (For x16, PRSNT#1 is pin#1-side-A, and PRSNT#2 is pin#81-side-B.)
It might be a bad idea to connect these two before the x1 extender is in, because it could indicate a card was present when not. But maybe it's harmless; I really don't know.
