[SUCCESS] Ryzentosh 5900X 580RX B550A [Big Sur ✓, Monterey - IN PROGRESS]

For Ethernet compatibility I would buy a gigabyte b550 board with a Realtek Ethernet (2,5 gb working with rltlucy kext)

I would search in this forum, some users have that board like and it seems it works well in Ventura

Asrock x570 could work but I have no recently test done and it has an intel i211at Ethernet that in my trx40 rig does not work

Thanks for the EFI, I tested it and sadly it rebooted aswell (monterey) but i can see no error logs in my USB Device.

therefore i was more experimenting with big sur and modified my EFI a bit and changed the kexts order. I was able to start the installer.

I formatted my SSD and selected it as device. Everything seemed to work smoothly.

Then the PC rebooted and the installation continued, usual progressbar with "x minutes remaining" after that my new issue begins.

i am seeing a notification which is saying:

"An error occurred preparing the software update"

I attached my Big sur EFI below.

This is what i am seeing :
