Thanks
@Oloorin for this Guide, after failed attempts following another guide meant for graphics card too I decided to just use the on-board as I wasn't getting far. My Geforce 210 has some age already and probably becoming non-compatible by now. I'm selling it and most likely getting a GTX 760.
I did a fresh Mojave install, wiped Sierra and started over.
Followed this guide as it comes but:
Used both AppleIntel and Atheros ethernet kexts for both ports to work;
Clover was already in full resolution for me so did not change BIOS.
Boot was not smooth, it would restart during boot, USB 3.0 ports would not work.
I tried injecting Intel at clover screen, and it boots fine, but still 5 minutes to boot (I then added Inject Intel with Clover Config.)
I then realised my Geforce210 card was still inside, removed it, now booting time is now 50 secs.
All the rest is working including graphics, Wifi and Bluetooth (BCM94352)
I removed the apple.com power managements kexts but Sleep still makes it restart, I went back inside L/E and one of them was there again(?) so put them both back in.
