I collected information and put it on
http://www.win.tue.nl/~aeb/linux/zip/zip-1.html
You see that the geometry depends on various things -
only the disk drive industry with a long tradition of
strange trickery can invent such schemes - the drive knows
about what DOS usually writes in the first few sectors of
the disk, and changes that a little, to let DOS think that
it is a fixed disk, or a big floppy, depending on the setting
of a jumper.
I have not studied the Linux driver code recently, and
do not possess such drives myself (yet).
