Thanks for your particular explanation.
I have not seen the boot process of Linux in detail until now... I'll
study harder.


I enabled keyboard and VGA support in Linux configuration and changed
"console=ttyLv0" to "console=tty1" in the kernel command line.
Then, I got the login prompt on tty1 and could use bash of the ramdisk
on L4Linux finally ! :)
It seems to operate well.
I also tried using DOpE on tty1 without keyboard and VGA, then it works.
I would like to express to you my deepest gratitude for having spent
much time on taking care of my work.


Lastly, I have a small question.
With keyboard and VGA support enabled, I get the following prompt on
the serial console (not on tty1).
(When I use DOpE, it doesn't appear because keyboard and VGA are disabled.)

If I type "g" on above prompt, the sequence re-runs and then I get the
login prompt finally.
The messages on tty1 at this time are the following.

Is this input always needed ? I don't think so.
Are there any problem in my kernel configuration or boot settings ?
My now kernel configuration is the same as the recent mail (based on
the given .config) :
