The steps are reversed! First plug in the power cable, then flip the
switch on, _then_ jumper the green wire. Some use a 'momentary' jump,
others have to keep the jumper on.
I'm pretty sure one of those two indicates a 'fault', but haven't yet
figured out which. Then again, one way (or the other) might just be a
change to accomodate the newer MBs which support the "boot after power
failure" mode. :-((
Good luck... M.
