@bearcat dont know what i did but right now I can see the controller and drive while booting. its also possible to enter the raid bios, I have only 1 disk attached jbod so there is no raid configured. the sil3132 is indeed a raid controller but i thought this should be no problem as what i have seen on the compatibility list. dont know if it is possible to reflash it to a nonraid controller. now i see it while booting I went into the grub loader and used the following command Appandix SataPortMap=62 (6 for the onboard en 2 for the controller after the command i pressed esc and did a baremetal start but without succes.
