Installed video card on RSC-R2UU-A3XE8 riser card with X8DTU-6F+ motherboard. IN BIOS->Advanced_>PCI/PnP Configuration->Boots Graphic Adapter Priority,
I select "Offboard VGA". There is not video output on my add on video card. Unless I move the JPG1 jumper pin from pin 1-2 to 2-3. Is this BIOS bug or defected riser card.
If you select ""Offboard VGA", video card install on J1 PCI slot will got video output. RSC-R2UU-A3XE8 riser card is install on J2 PCI slot on motherboard. Please select "Slot J2 PCIe2.0 x16".
