Are you sure?
The Genie Pro 2.0 I've got was formatted like a floppy, that is:
NO partitions (you have to mount it as /dev/sd?, no number):
/dev/sdb /Mst vfat user,noauto 0 0

So it is a "fat" type (probably fat16) filesystem, with the BOOT
blok at the beginning, no MBR, cq partition table.

In fact, this is the first blok (dd piped into od):

You'll even see the DOS filenames there (IO.SYS, MSDOS.SYS).
And it IS a fat16 (see line 000060) file system.
