Z890 Pro-A = x4x4x4x4 Bifurcation?

[silent303]

Hi there,

i wonder this mobo can be changed to x4x4x4x4 instead of x8x4x4.

I tried my own with this guide. 
https://github.com/BoringBoredom/UEFI-Ed...sage-guide 

I was able to find the parts, imported them in:

But now i am stuck, dunno what to do here :-)

Maybe someone can help

Have a nice day
Tobias
