guys - was tinkering a bit last night to see if I can get my 9900k and ASUS Prime z390m-plus (mATX, latest bios) and Vega VII to work. Have done a few machines, but this one seems a little DSDT/SSDT work
Followed basic procedure of installing base-image from here for 300 series only modified my SMBIOS and ran the dump.
