Don't want to open a new forum so sorry for reply to myself.
I found out why it doesn't want to boot OS4.0.
The problem is the ppc soldering..I think.
The 060 already has been fixed by amigacenter and that part is 100%.
But the ppc side needs a push downwards to boot up.
I know it is not advisable to push against the ppc but as there is no company which can do these repairs I will make a bracket which pushes it down.
Don't think a small force is that bad for the ppc.
