High Sierra on i5 2500k Sandy Bridge

Hi everyone!

When I'm trying to boot the installation stick, I get

00:000 00:000 OCB: LoadImage failed - Unsupported 

62:265 62:265 OCB: LoadImage failed - Unsupported

I followed the opencore guide for SandyBridge on dortania

My config.plist is download

Any recommendations, fixes?

Best,
Hannes
