Please choose your boot method below:
 embedded    Boot installer for embedded devices (serial 38400,8,n,1)
 normal      Boot installer for normal pc's
 bko         Boot via http://boot.kernel.org

}}}

Embedded kernel + init zitten in initrd_embedded en linux_embedded.

Iso is normale installer iso.

Zorg dat guest/guest-account bij tftp samba share kan.

Via SCC dhcp aanpassen zodat hij bootp doet en pxelinux.0 laad.

Pas grub aan na 1e boot
