Hi at all,
I'm new of this forum.

I would test ghostBSD on my t400 with libreboot.
I dded the iso on a usb drive and it start normally on virt-manager but not on my libreboot.

This guide is not good: https://libreboot.org/docs/bsd/freebsd.html

I changed any parameter and the first row

kfreebsd (usb0,gpt3)/boot/kernel/kernel

give me an error: anknow file system

Any suggestion?
