Yes! The GRUB_TERMINAL=console setting works...at least I moved forward.Now I can access and edit the GRUB menu.
Now the last messages visible on the screen are: Unable to read GCT! VBT signature missing Then the screen slowly turns white. The problem seems to be in the video interface integrated in the Atom E6xx. I tryed several linux command option like video=640x480 but without effects... Any suggestions ?
