Correct.  You might want to use:

	# fdisk -B -b /boot/mbr

to make sure BootEasy is not installed instead of a plain MBR.

Summing it all up in "steps", something like the following would be fine:

	1. Make sure the correct partition is 'active'.

		# fdisk -u /dev/ad0

	2. Install plain "MBR" boot code:

		# fdisk -B -b /boot/mbr

	3. Reboot
