I tried all three suggestions; the cards came with one ribbon cable
each with those I tried all combinations; one card, two cards, I can't
get it to work. I tried e-mailing support, but this also doesn't seems
to work (no reply from them yet!).

Does Boot Prom Rev F support expansion cards?

Any way to check the functioning of the ribbon and power cables?
