Can I make a non-FreeBSD disk/USB stick bootable using something like gpart bootcode -b /boot/bootxyz da0 for making a DOS or Linux bootable? If FreeBSD doesn't have the appropriate code what could I use instead?
FreeBSD contains a additional MBR bootloader /boot/boot0 who provides a small boot-menu. This can chain-load the boot-sectors of other operating systems as well. I know this working with FreeBSD and Windows.
I don't know if Linux would boot like this, because Linux comes allways with GRUB. Does the Linux loader "LILO" still exist?
