I've spent about an hour on your problem and that was the limit of time I could afford today. Here are my first ideas:

1/
If you have the BIOS board (your first photo) then your 18000 is not compatible with Origachip. That would be clear to anyone who understands English or Italian!

2/
Because the orientation of your chip is different from the Origa diagram, I'm having a tough time confirming your solder points. But I can see variances from the Origa diagram and I must look into this further. This will take me two or three days more because of my time constraints.


If you agree that your 18000 is incompatible, let me know so I don't look at it any more.

Kind regards
