Anyone have a picoBSD image?

[Julian Elischer]

I need a picobsd floppy image, (anything that can get me to a shell
that will allow me to
dd if=/dev/zero of=/dev/ad0 bs=1M
)

for a machine that I need to wipe the disk on (it has a floppy and 
drive  (windows) I need to wipe).
of course if you have a better way to zap several disks on an
old 486 PC that would work as well.. (no not 'jump on them')
