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 ?

Thanks
F.
