[HELP] BigSur on laptop dell 3442 A-15 with opencore

[Primitive Tutorial]

I've installed BigSur successfully on my laptop dell 3442 A-15 with opencore following dortania's Haswell guide (first time trying opencore, before I did it on Catalina with clover and it works).

There are some problems and I would like some help to solve...

 

Working:

- trackpad, intel graphics 4400 and only 1/3 USB port

Don't working:

- laptop keyboard, Bluetooth, WiFi, network connection via cable, sound, 2/3 USB ports (I didn't made USB mapping yet)

 

I tried olaria premade EFI for Haswell, but the only thing that works is the 3/3 USB ports. Link: https://tinyurl.com/36pjy29u
