Hi Ipmark. Wow!!! That was Fast. I wrote my post Being at work late in the evening - I woke up early in the morning(kids) - and already have what I asked for. Thanks a lot - I will post results of course.
Ipmark, I couldn't manage to get into windows this time before the motherboard bios automatically restored the old marvell version. After fiddling a bit with mmtool and a hex editor I got close to replacing all parts for the Marvell, but in the end it seems I bricked the controller. So now I simply moved the ssd back to the intel port. Screw Marvell.
