Modified versions of various blank floppies
-------------------------------------------
These modifications reduce the number of
FAT tables from 2 to 1 and also reduce the
number of root entries down to 16 files,
which frees up some extra storage space.

The 1.72MB format can ONLY be used on Win9X
systems on real hardware, as not even WinNT
can access tracks 81 or 82 on floppy disks.
Disk image programs like WinImage can still
access files within 1.72MB floppy images.
