Explain Multiple Extra Terminals on P4 Board

Just today, a P4, 1.8-GHz processor fell into my lap. I bought a DFI NB70-SC board and I get no post, no beeps and no video. The main board's LEDs do light up and the fans do come on. The 300-watt power supply is known-good.

There are some extra power connectors nearer the center of the board. On one, the pins look like the ones on a standard ATX connector except there are only four pins in a square arrangement. The other power connector (right against it) is a six-pin that looks like the power connectors on the old AT boards.

What are these connectors? Do I need a special power supply to run this board? My present ATX power supply does not have these terminals on it.

 

This problem is solved. Those extra connectors are essential and do require a special ATX power supply with extra connectors.
