The back was covered with a sticker that I didn't want to remove. The interface to the RAID card is a two pin connector so its active interface would be two pins.

I also suspect a two-wire communicator of some kind that transmits a small number to the card. Could it be a challenge-response method where the card sends a number to the chip which does some conversion and sends back a result?
