Can I ask for your help yet again?

I switched my SAS controller to one that is supported by OSX, but when I switched the boards, it boots fine in Windows and Linux but High Sierra no  longer boots. I get a blank screen now. Do you think I need a new DSDT? I assume I have to remove the board so that I can boot and remove the present DSDT and re-install the board and see if it will boot and then send you a new file?

Thanks

oh boy...

 

I have a problem. I can't boot into High Sierra with the new board even without the DSDT file. Not really sure what to do next. Maybe remove the thunderbolt board and try like that...
