MaLd0N:
THANK YOU, THANK YOU AND THANK YOU.
Here you have the newly generated Send_me-file. I read your post several times and figured out that I might need to replace the whole EFI folder. I've tried that and computer started with the first generated DSDT-file that you created, I can now see the PCI info on the computer. But I still encounter a few problems.
WiFi-card with Bluetooth should work "Out of the box". The WiFi works great but not the Bluetooth, maybe the problem is related to one of the USB ports where you need to connect a cable for the card to work. Not able to connect Apple Bluetooth mouse & Apple Bluetooth keyboard.
Thunderbolt using USB 3.1 not working
Not possible to change the sound volume on HDMI device
How to see if Intel SpeedStep Technology is activated
And to my last question, can I copy your EFI folder to my Catalina Boot USB including the patched DSDT-file to get rid of unnecessary kexts? I would like to have a clean install.
