@ MagicSmoker - That solved it! Thanks for the hint! Just need to figure out how to get all the GPUs detected by xmr-stak!

I have a ONDA D1800 BTC that I got running using the VGA out and installed an operating system. I tried updating the BIOS to the latest Vega update which went fine, I reset and now I get the POST short beep but no video out through the VGA. Other than no video it seems fine, the OS starts up, I can still ssh into it but I'm not getting any video out. I've tried clearing the CMOS which I'm not exactly sure how to do (reset button in back? blue jumper? remove battery?) but I never get the long beep (I think that's the reset beep?) I'm stumped, anyone have any ideas?
