Wow thanks. I was getting a boot loop of Clover -> Apple logo -> Restart -> Clover ...
Removing the Topology line and using the rest of your xml as a replacement finally worked.
I installed Clover latest (43xx), and then reinstalled Clover 4200 over it after problems for anything looking for help on a fresh install. I did that before messing with the XML above, so it's very possible the Clover version had nothing to do with it finally working, as 4200 was doing the same thing until I messed with the XML.
Next item to take on is GPU pass-thru.
