Administrators Bronxteck Posted December 7, 2017 Administrators Share Posted December 7, 2017 check clover boot log and see if clover is auto generating dual link then. also if your using a patched DSDT check to see if dualink is set in it and if so change it accordingly.

Administrators Bronxteck Posted December 7, 2017 Administrators Share Posted December 7, 2017 origin folder is unpatched asl files. if you are using a patched dsdt in clover/acpi/ patched then you use a dsdt editor to make the edit like maciasl. do a search for dual link when you find it then see if the variable is set to a number 1 or number zero. recompile it and resave it then test.
