Here <your_disk> could either be just disk name, e.g. wd0, if you use it in dedicated mode, or there is a single FreeBSD slice on it, or particular slice name, e.g. wd0s2 (if you have multiple FreeBSD slices). To install the standard boot manager (/boot/mbr), use `fdisk -B <your_disk>'. To install FreeBSD boot manager which allows you to choose the disk/slice to boot from, use `fdisk -B -b /boot/boot0 <your_disk>'.
