Operating System: Mac OS (Note: might work with other versions of this os.)
from windows file @ driverguide.
changed prog.def file to represent
saf model # and saf firmware
i upgraded the firmware on my
6424s in os 9 with this setup,
i was longer using this
burner(moved to faster model) so i
was a bit fearless when it came to
trying such a thing, but you may not
want to try this if there is nothing
wrong with your burner.
