I will come back to you soon. I have all my ram memory currently in my X299 build. My X99 build is off at present.
The aim is to create the SSDT without the help of any DSDT, as I want to apply the same procedure for a SSDT-X299.aml.
The problem is that if I take my SSDT.aml and follow your new SSDT.aml example to implement e.g. the HDEF Device, it does not work at all.
As all other HDEF device entries in my file are still correct and valid, I guess your HDEF _ADR entry is not valid for my system. I know how to find the value within the DSDT file, but I don't know how to find it without any DSDT. Do you understand? Because I can't see any _ADR address in IOREG for HDEF.
Well as soon my X99 system is on-line, I will try to extract the required HDEF _ADR information from my DSDT, if there is no other way or workaround.
In the worst case I will send you all information you request above.
Cheers, man and many thanks in advance,
KGP
