I have managed to compile my dsdt.aml, but I can not find any solutions for my errors.

Thank you for helping.
I am very new to editing DSDT
I tried editing adding what you have told me, but I still cannot get it to compile correctly, maybe I am inputting it in the wrong place. Is there any way you can go into more detail with where to put the edits?

Actually, I figured it out! Thank you!
Another thing, every time I compile, I get this:

External (\TNOT)
Error 4057 - Name already exists in scope ^ (\TNOT)

Every time when I'm ready to save the dsdt, I just go delete the line and it allows me to compile. Is that what I should do?

And I still don't know what to do about the two _CRS errors. Any ideas anyone?

you can compile you dsdt using iasl in windows,
try iasl -tc dsdt.dsl
output file dsdt.aml 53 k

It still compiles the same. I always get it to compile by deleting the (TNot) line, so I'm not too worried about that. But I am not sure how to edit the dsdt to solve the two CRS warnings the compiler is giving. Any idea how to edit it, or any idea what the two warnings/errors mean?

you can skip the CRS ist just a warning, also if you want you can search for solutions in google, or just skip this one and test you installation

p.s.:
try to download dsdt from this page to see how other slove problem whith CRS
