The floppies are broken up into, essentially, two sections:  a label track and
the data tracks (note plural vs. singular).  The first track on the install
disks is used as a label and is accessed by the device /dev/rdsk/f0q15dt, where
the trailing 't' indicates the entire disk "total?".  To access the data after
the first track (i.e., tracks 1..79), use the device /dev/rdsk/f0q15d.

Since the first track is also generally used as the boot track on floppies
capable of booting, i frequently create the following links in /dev/rdsk and
/dev/dsk/:

ln f0q15dt f0		#default format for floppy drive 0 is 1.2MB
ln f0q15d  f0-boot	#1.2MB drive "minus" the boot track
