On my personnal computer, when the message "Loading stage 1.5" is wrote, it
is immediatly suppressed by the menu.

On the PC104, when it is displayed, it takes a very long second befor the
menu is displayed. During this time, I can, for example, press the down key
two times, press enter and when the menu will be shown, it is going to
remember my action and do it.

I know that one or two seconds for loading grub on a embedded system is not
maybe too much, but it is for my needs. The linux after boot in less than
ten seconds and loosing 2 seconds for grub, is too much for my needs...

Is there a way to activate a debug or verbose version to know what it is
happening ? I think it would be the best way to know what is taking some

Thanks for your answer.
