Hi @Fernando and many thanks to you As well for leading me to the answer of my questions.
And sorry for not following the forum rules due to new in the forum.
As i told @hancar I knew the bios Mod would give approx. 6 x improvement and it really feels great to blow some extra life in a rather old system.
I is like having Porche only using up to 4th. gear and finely jumping to 6th. gear for the first time....;-)

Thanks
