SpaceInvaderOne Posted July 21, 2019 Share Posted July 21, 2019 Whilst getting ready to get a new AMD Ryzen 3900x I found that the required bios update for an MSI x370 and an Asrock x470 broke passthrough. Not sure if this is going to be with all motherboards. Dont know if x570 has this problem but becareful! I believe since Aega 0.0.7.2 there has been a problem with passthough. The agesa that was in the bios i upgraded to in the MSI ans Asrock was AGESA Combo-AM4 1.0.0.1 Quote Link to comment

dodgypast Posted July 22, 2019 Share Posted July 22, 2019 There's a thread on the level 1 forums about this: https://forum.level1techs.com/t/attention-amd-vfio-users-do-not-update-your-bios/142685/54 I've also been in contact with Gigabyte about it and they're reaching out to AMD. Hopefully your video will raise awareness as there's been quite a few threads about this issue here and on reddit. Quote Link to comment

SpaceInvaderOne Posted July 27, 2019 Author Share Posted July 27, 2019 Heres a short guide on how to downgrade the bios on an AMD motherboard if you have the same problem that I did. This is for AMD motherboards that use an AMI bios as many do. Hope its useful Quote Link to comment
helin0x Posted August 1, 2019 Share Posted August 1, 2019 Has this been sorted yet or are we still stuck without a solution? Quote Link to comment
