how does one format a floppy to use a vfat partition

[<jcunningham@engine8.com>]

hi list, i've been reading tons of docs on mkfs and mtools because i need
to make a copy of a somewhat corrupt ms floppy which is vfat but can't
find the command to do so. so, how does one format a floppy to have a vfat
partition and not just an msdos fat or fat32 partition?  i re-rolled my
kernel to support vfat but still cant get it working.  am i missing the
obvious here?
thanks, justin

ps:  please reply to my email as i am not currently on the debian-user list
