i flashed using the 1.8 on my previous post from the german MSI site
Ah. Time to try the hot-swap (hot-flash) method. See Collected Wisdom, it links to a description of hot flashing at Rainbow's site.
Did the picture of the 6147 at the German MSI site look like your board ? Check the top surface of the board for the ID, it should say MS-6xxx somewhere.
