What I tried is:
start board and get grub console
set gfxmode=1280x1024
terminal_output gfxterm
(after that command I get some strange characters on screen (looks
like ? in suqare)).
Anyway I tired to type background_image command but there is only ?
output (not readable unfortunately).
Any other ideas? Thanks.
