Or by restoring from an up to date backup:

	$root dd if=/dev/rsd0 of=/var/backups/mbr.rsd0 count=1	# save
	$root cp /var/backups/mbr.rsd0 /dev/rsd0		# restore

Or by remembering some values from an out of date backup:

	$root fdisk /var/backups/mbr.rsd0
	fdisk: Can't get file status of /dev/r/var/
	Cannot open disk /dev/r/var/ (No such file or directory)
	$root mail -s "someone broke device independence of fdisk" \
	      j@uriah.heep.sax.de				# :-)

and remembering other values in another way.
