What needs to be modified to make it work on custom hardware?

[Forte500]

I was only able to get this result by adding the EC path to SSDT-YVPC:

It is not entirely clear to me what specifically I should change within the program. I tried to take a look at it but at least at first glance I didn't seem to see anything in particular having to do with EC registers? or something like that idk

I hope you can give me some hints, thank you.
