If this is on a Sam460ex and not on a Sam460cr, maybe MorphOS defaults to the VGA output of the on-board SM502 and must be switched to the PCIe graphics card after boot? Just a guess.
Yes this is a Sam460ex...I will check if VGA has any output..
But anyway it would be better if it switches to 6570.
