Heh.  It's not like you only get one chance to rewrite the boot blocks
on any particular drive.  If anyone needs to (re-)install the FreeBSD boot
blocks, then you can do very simply it by:

   boot0cfg -B -b /boot/boot0 /dev/ad0

or even

   fdisk -B -b /boot/boot0 /dev/ad0

Or if you need to boot from a serial console you can change /boot/boot0
to /boot/boot0sio

	Cheers,
