Try powering up with just a single GPU and see if that gets you into the UEFI.]]> Thu, 07 May 2020 15:21:32 +0000 https://forum.asrock.com/forum_posts.asp?TID=14305&PID=75151&title=asrock-x399-taichi-cant-boot-to-uefi#75151 <![CDATA[ASRock x399 taichi - can't boot to UEFI : Ever since I upgraded my x399...]]> https://forum.asrock.com/forum_posts.asp?TID=14305&PID=75143&title=asrock-x399-taichi-cant-boot-to-uefi#75143 Author: SeanLee

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]]> Thu, 07 May 2020 06:27:35 +0000 https://forum.asrock.com/forum_posts.asp?TID=14305&PID=75143&title=asrock-x399-taichi-cant-boot-to-uefi#75143
