devbios generally knows how to do this for certain chipsets, including
the 440. Unfortunately some mainboard vendors additionaly protect flash
write with some undocumented GPIO circuit, so supporting the chipset
alone is not enough. There is not much you can do except gnireenigne 
esrever existing firmware or trying out all possible GPIO lines (and
combine them etc) The first is probably illegal in some countries, the
second might destroy your hardware, esp. on laptops.
