Biostar TB85 board, need BIOS help, no GPU's showing

I recently got a few TB 85 boards and all seems to work well, except
the main thing I need to work. I know this is a BIOS setting issue.

I will post a pictures of my settings. Everything in the "chipset" area of
the BIOS is set to auto.

I am running RX 480's. Stock ROM for now. Only trying to get 1 GPU
running before I start adding the other 5.

Celeron G1840 CPU, in case it matters.

Any help would be appreciated.
