Monterey mbr no detect my keyboard and mouse in the menu installer AMD FX

[felipe09]

Hello

I created a usb and installer with monterey mbr, the problem is that I get to the menu because it doesn't detect/doesn't sync the keyboard and mouse. My pc is

AMD FX 6300 3.3 Ghz
ASUS M5A78L M LX
4GB RAM DDR3 1600 Mhz
500 Gb Hard Drive

Can anyone help?

U need one specific EFI folder for your hardware.

It seems that what I'm trying to convey isn't being translated correctly. The problem is that no key on the keyboard responds to what I do in the menu of the olarila Monterey/High Sierra MBR. The keyboard is connected, but neither does the mouse. Even if I move it, the arrow doesn't move. I tried copying the EFI, but it doesn't work because I can't do anything in the boot menu because it doesn't recognize the keyboard or it stops responding.

First thing is generate usb kext on windows with usbtoolbox

I used the “EFI MOD BULLDOZER” folder and added some files of opencore to the “drivers” subfolder.

 I managed to get the keyboard to work in the menu, but when I try to start loading
 in the menu, it returns to the menu again and so on.
