## FreeBSD
> Jak odpalić `qemu`? Skąd wziąć obraz?
Obraz jest dostępny na stronie głównej [freebsd](https://freebsd.org) ale __wybitnie__ nie chce on się porozumiewać z qemu. Aby cokolwiek wystartowało jest potrzebny _u-boot_ i zmuszenie _qemu_ do potraktowania go jako obrazu biosu. A i tak ostatecznie kernel dostaje gdzieś na początku bootstrapu błąd związany z wykonywaniem nieznanej instrukcji.
Ostatecznie odpaliłem to na fizycznym sprzęcie.
