6 . Applies the command ' sync' syslinux to finish the linux.img image ;
7 . After all settings and installations test it with qemu , for example, the following command qemu linux.img ' ;
8 . If everything ok the system will boot and will fall in the basic shell . But the current attempts can not enter the terminal ( shell ) ; I leave here resgistred steps if it can help someone or someone can help me .

No entanto, não consegui executar init , como mostra a figura.

Em outros testes, eu obtive outros problemas de kernel panic, já que root não foi encontrado.
