       ALTSCTR	     0x09
       CACHE	    0x0a
       RESERVED	    0x0b

       The data in the Flags column above indicates how the partition is to be
       mounted, as follows:

       Name			   Number
       MOUNTABLE, READ AND WRITE   0x00
       NOT MOUNTABLE		   0x01
       MOUNTABLE, READ ONLY	   0x10

	 FREE_START=0 FREE_SIZE=0 FREE_COUNT=0 FREE_PART=34

       Example 3 Using the prtvtoc Command on a Disk Over One Terabyte

       The  following example uses uses the prtvtoc command on a disk over one

	 * /dev/rdsk/c1t1d0s2 partition map
	 *
	 * Dimensions:
	 *     512 bytes/sector
	 * 3187630080 sectors
