you can also try popping the CMOS battery out and leave it out for a few minutes with the PC unplugged or PSU turned off and hold power button for a couple seconds to totally discharge any residual power stored in the motherboards capacitors]]> Fri, 14 May 2021 20:48:09 +0000 https://forum.asrock.com/forum_posts.asp?TID=18808&PID=87119&title=b550-taichi-wont-let-me-in-bios#87119 <![CDATA[B550 Taichi won't let me in BIOS : What UEFI version did you flash...]]> https://forum.asrock.com/forum_posts.asp?TID=18808&PID=87065&title=b550-taichi-wont-let-me-in-bios#87065 Author: ket

What UEFI version did you flash to? Do you have a dual monitor setup? Try turning the other monitor on and see if you get a display then as unlike when the VGA driver is loaded in Windows you'll only get a display output from the primary monitor during POST. You can also try reflashing the firmware from Windows if the other suggestions don't work.]]> Thu, 13 May 2021 05:02:40 +0000 https://forum.asrock.com/forum_posts.asp?TID=18808&PID=87065&title=b550-taichi-wont-let-me-in-bios#87065 <![CDATA[B550 Taichi won't let me in BIOS : Just bought what looked a very...]]> https://forum.asrock.com/forum_posts.asp?TID=18808&PID=86975&title=b550-taichi-wont-let-me-in-bios#86975 Author: D3adsongs

Just bought what looked a very lightly used B550 ASRock Taichi. I was able to update bios with a flash drive to make my Ryzen 5 5600x work with the mobo. So far the mobo works great and boots up fine but whenever I try to get into the bios via F2 or Delete I just get a black screen and the error code A9 on my motherboard. I have never seen the bios command not work before, what can I do to fix this??? Hitting the clear CMOS button did not fix this, please help thank you!
