This 3 are samples for waath i have understand i have to do, but, still
with no luck on making EMC2 work with this card.
I have based this on the 5120 sample config files found on EMC2 CD.
Kirk Wallace sent me some directions, and:
1) i have no "man hm2_7i43" on my linux (no manual found answer

There are insanely fast turn-off diodes on the market. By trying out a
