biostar btc pro 12 cards

[deskless]

The motherboard is not recognizing 9th card. I am using EthOS which is a Linux based platform. Any suggestions what to do?

No issues with the Risers because I switched cards and still seeing only 8 cards.
Thanks

Update the bios of this motherboard to the latest version. Once upgraded when it boots up it shows you if it is a problem of the riser slot or not. If all riser slots look green that means you have to look elsewhere but first try to isolate a riser error by doing so.
