Asrock Z390M-ITX A/C unlock bios Mod request/help [DONE]

Trying to unlock all of the menus in this one, particularly the PCIE speeds.
I want to set the “wifi slot” to Gen1 because I’m running something else in it and it’s having issues.

Didn’t have much luck setting what looked like the correct submenu to “user”.

Actually. Nevermind.
While I was making screenshots to post here, I figured out what I did wrong.

Rather than delete this. Just in case anyone else ever wants to do this:

That unlocks the additional menus I needed to change the root controller #7 to Gen1.
We’ll see if my device plays nicely now.

Figured I should upload it.
The only difference to stock is those menus to get to the PCIE settings are unlocked.

And yes. The SSD on the WIFI port via an adapter is now not having IO errors and is 4x faster than it was before.
