To initialize diskette (just for data):

dd if=/dev/zero of=/dev/fd0 bs=512 count=1   (zero first sector)
v2_init /dev/fd0 32 0 0                      (actual init)

(32 = max number of objects on diskette)

To save file:

file_to_v2obj -f /joost2/Projects/C/C-Lib/testapp.app -t "SYS." -n testapp.app -o - | file_to_v2fs -p /dev/fd0 -f -

where /joost2/Projects/C/C-Lib/testapp.app is the actual file, 
testapp.app is the name you want it to be called

To delete file:

v2fs_delete -p /dev/fd0 -m testapp.app

To list contents of V2FS partition

part_info /dev/fd0

To load a diskette image from linux:
