couple notes:
1st dont need busratio =20 (this is only used in 10.5.6 and earlier because voodoo kernel was required. if you use the com.apple.boot and smbios in the extra zip I uploaded it has the correct config.

2nd dsdt.aml is usually placed in the root path "/" and you can hide it with this command in terminal chflags -R hidden /dsdt.aml (if you want to unhide use hflags -R nohidden /dsdt.aml" actually you should be able to hide extra folder also.)

3rd in some cases I found that addeding -x32 or -x64 doesn't work. you may want to try arch=i386 or arch=i386-x64

4th In some cases you need your 1st network adapter to show as "en0" and "built-in" specifically when using netflix watch it now. so you might want to use efi studio to combine your graphics and ethernet string

Have fun and good luck nice tutorial btw

thanks
