okey i think i narrowed down what the problem really is! i can enable fast boot now w/o freeze in the bios but i had to actually change the usb support setting in the fast boot! with partial initialization the bios freezes but if i change it to full initialization it will not freeze anymore so the freeze is caused by usb or somethink... but im happy now since i figured out the real problem and i can use fast boot now w/o problems!:) Still odd that this doesent happen with older bios version but hey its all good now and hope they fix this later bios realese:p
