Can anyone help me install the drivers for the Z77 Extreme4 Catalina?

[Epaminombas]

I tried the High Sierra, but my RX 590 doesn't work.

The Catalina 15.4 is running on the RX 590 and is performing very well and very fast.

The problem is in running the network card, the audio on the motherboard and making the boot without the pendrive.

 

 

These tutorials do not explain exactly which program to use to edit the command lines, what do I do?

I installed Kext in the EFI folders and with the program that runs Kext and still without success. What am I doing wrong ? And so far I don't understand how to use the programs to make the boot work. 

 

 

 

Did you think I have all the necessary files? What exactly do I do now ?? Can someone explain to a layman?
