The BIOS update has resolved the keyboard/back panel/A2 issues. I'm mid windows install.

Thank you for the assistance on this! ]]> Fri, 31 Jul 2026 01:07:39 +0000 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201876&title=z890-taichi-cant-get-into-bios#201876 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201873&title=z890-taichi-cant-get-into-bios#201873 Author: Xaltar

Your board has a clear CMOS button on the rear IO right next to the BIOS flashback
button]]> Thu, 30 Jul 2026 02:00:36 +0000 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201873&title=z890-taichi-cant-get-into-bios#201873 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201872&title=z890-taichi-cant-get-into-bios#201872 Author: NemoZemo

Thank you again,

I am going through the process for the CMOS reset. Question that came up for me is as I am reading through the manual, I'm not finding a jumper for step 3 of the link you provided.

Google says this mobo does not possess one, but just looking to confirm this as Google is not that trustworthy a source to me. ]]> Thu, 30 Jul 2026 01:08:14 +0000 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201872&title=z890-taichi-cant-get-into-bios#201872 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201871&title=z890-taichi-cant-get-into-bios#201871 Author: Xaltar

Try this and see if it helps:
https://forum.asrock.com/forum_posts.asp?TID=630&title=how-to-clear-cmos-via-battery-removal

If there is some kind of BIOS glitch happening that is preventing the keyboard from
detecting that should clear it.

If that still doesn't help it could be that your board doesn't have an up to date
enough BIOS for your CPU which requires BIOS 3.09 but will POST on 2.22. If the
BIOS is older than 3.09 it could be causing your issue. You can use the BIOS
flashback button on your board to update to a supporting BIOS version. You will
find instructions in your board's user manual:

Page 55 of the PDF (51 on the printed page).

Good luck ]]> Thu, 30 Jul 2026 00:29:14 +0000 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201871&title=z890-taichi-cant-get-into-bios#201871 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201870&title=z890-taichi-cant-get-into-bios#201870 Author: NemoZemo

Hello & thanks for creating this thread!

I have removed the SSD from the M2.1 slot (so no SSDs are present).

I have tried 3 different keyboards (2 wired, 1 wireless) & none have been able to input a selection from any of the rear ports, lightning ports included. All have the numlock key light come on, but no input works.

At the end of this post I have put a couple of screenshots to show what the display is showing.

Thank you

Try the "Lightning Gaming" ports for the keyboard, they are meant for use with
a keyboard and mouse. If that still won't work then try a different keyboard.

Another way to get into the BIOS is to remove all storage devices, the system will
automatically enter BIOS on boot when there is no boot device present.

Hope this helps.]]> Wed, 29 Jul 2026 03:29:07 +0000 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201868&title=z890-taichi-cant-get-into-bios#201868 https://forum.asrock.com/forum_posts.asp?TID=113557&PID=201866&title=z890-taichi-cant-get-into-bios#201866 Author: NemoZemo

Hello,

I am in the process of my 4th pc build, but 1st in 9 years.

Currently I have 1 stick of ram installed to B2 port. Trying to boot to BIOS. When powered on, it goes to the Asrock screen with F2, F6, F11 on the bottom right, but I cannot use the keyboard to get it to access any of the menus. USB Keyboard, using the back ports on the mobo.

The mobo code is showing an A2 code, but since I can't access the boot menu options I am stuck.

I have no SATA HD drive connected.
