The Bios is the original 1.0. I didnt expect to need a BIOS update as I thought buying a B550 would be compatible out of the box buy I guess I was wrong.

No I didnt have an older Ryzen or know anyone that has a one I can borrow.

Any other way to update the bios? ]]> Fri, 01 Jan 2021 06:30:24 +0000 https://forum.asrock.com/forum_posts.asp?TID=17668&PID=82698&title=b550-pro4-wont-post-boot#82698 https://forum.asrock.com/forum_posts.asp?TID=17668&PID=82664&title=b550-pro4-wont-post-boot#82664 Author: ThreeDee

do you have the P1.20 BIOS installed on this motherboard? If not, then you'll need to borrow a 3000 series CPU to flash to version P1.20 for Ryzen 5000 series compatibility. ]]> Thu, 31 Dec 2020 15:27:43 +0000 https://forum.asrock.com/forum_posts.asp?TID=17668&PID=82663&title=b550-pro4-wont-post-boot#82663 https://forum.asrock.com/forum_posts.asp?TID=17668&PID=82661&title=b550-pro4-wont-post-boot#82661 Author: mydogboggs
