Using the same EFI I installed Catalina with, when I get to the first install screen for High Sierra, I can't use the mouse or keyboard. I've tried cold boot with it plugged into each port with no luck.

Using an EFI pretty much based exactly on iGPU's build, but attached EFI folder for good measure.

So just an update. I pulled an old High Sierra drive out of a mac mini I had sitting around and boot to it using my USB EFI. It booted fine, but also no keyboard or mouse. Guessing I'm probably going to sell this motherboard and by one that for sure works with HS. Anybody have any suggestions?
Thanks!

I finally managed to fix my similar keyboard issue.
Turns out any keyboard with a USB hub was being seen as only a hub.
I tried an old Dell simple wired keyboard and just like that it worked!

After doing some googling, it looks like this was an issue for people upgrading to High Sierra when it first came out too.
Hope this helps.

WOW! That's great news! I can't confirm, but going to switch back from the Gigabyte to the ASRock and give it a shot.

It this is the case, this issue needs to be pinned at the top of the High Sierra install forum. It would have saved me 100's of hours.

Thanks for the update @ediblehandshake2, I'll let you know what happens on my end.

Ok! That works! New keyboard and BOOM! Install.
Thanks for your help. Will let you know if and when I get the GPU's up and running.
