12 megs of ram missing?

You don´t have to rip the zips off. It is the Fastlane that needs some configuration. So check them again  :-)
If you don´t have the manual then you can download a german version from Amiga Hardware Database
On page 20 setting 5 should be the right one. Have you checked the Fastlane-mems so they all work? Meaning checked them 4MB at a time?  :-)

Great that it works. Can you post some benchmarks and how you installed everything? When you get the scsi to work.
Me and others would be glad.  :-)

I fried my board with an active terminator.  :-( I´ve asked the french Amiga Repair center and they told me how to repair it but I think it ends up with sending them the whole board.
