+You will need to provide some information about your disk's geometry.
+Geometry info for SCSI disks was printed at boot time.  If that information
+is not available, use the information provided in your disk's manual.
+Please note that the geometry printed at boot time is preferred.
+
+IMPORTANT NOTE: due to a limitation in the disklabel(8) program, the
+number of cylinders on the disk will be increased by 1 so that the initial
+label can be placed on disk for editing.  When the disklabel editor appears,
+make absolutely certain you subtract 1 from the total number of cylinders,
+and adjust the size of partition 'c' such that:
+
+	size = (sectors per track) * (tracks per cyl) * (total cylinders)
+
+Note that the disklabel editor will be run twice; once to set the size of
+partition 'c' and correct the geometry, and again so that you may correctly
+edit the partition map.  This is to work around the afore mentioned
+limitation in disklabel(8).  Apologies offered in advance.
