Hi philipma1957,
I just bought 3 Onda B250 BTC-D8P and tried using it for simple mining os but it keeps hanging, I also tried it on ethos and kept getting kernel panic errors once I tried to install more than 1 gpu.
Could you advice me on your bios settings for this board and what I should do as I now have 36 rx580 8gb gpus and 3 of those boards that I am still unable to mine. Thanks, I have also dropped you an email, really hope you can help me on this, would love to talk to you and hopefully you can share with me your knowledge on these boards. Would really appreciate it. Thanks
