Help modify my ThinkCentre M900 Tiny Q170 for Kabylake?

@rycyve The problem is that the M900 only ever supported Skylake and never had Kaby Lake support added to any BIOS.

You might want to read this thread as someone did get it to work by combining the BIOS region from a M910 but unfortunately didn’t upload the modified BIOS, although they did say there were several isues.
