Konichiha,
Hi,
Ola,

After investigation, thanks to DrMax and Segfault without them
i can't find why... And i can try under my bad way for long time ;
https://svnweb.freebsd.org/base/head/?view=3Dlog&pathrev=3D338285

But,
I have an chiffred disk and the firmware maybe can't load at boot time.
May be need to add this firmware to the /boot/modules but I don't know
if it's the good way.

I'd like just have the full resolution in the boot loader and the KERNEL
boot for my work machine...

Please say me were the best way about my ask.
BRs,
Heitai.
