Ever since I upgraded my x399 Taichi to the bridge BIOS, p.230, I can't boot or reboot into my system BIOS anymore (I'm using the ASRock Restart to UEFI app). My PC boots, and key/mouse lights come on, but my monitors stay dark (amber colored power lights). I normally wouldn't care too much, but the BIOS update disabled AMD-V for some stupid reason, and now I can't power on any of my virtual machines. Any ideas on how to fix this? FWIW, here's some relevant system info: AMD Ryzen Threadripper 1950X 64GB DDR4 mem (2) NVIDIA GeForce GTX 1080 Ti (3) VX2739 Series 27" ViewSonic monitors |

Try powering up with just a single GPU and see if that gets you into the UEFI. -------------
