Firewire Connection??

[sterling]

HI All

I am trying to connect my firewire port on the front of my case to the header on the
Intel 865perll motherboard. The firewire connection on the motherboard has 10 connections. The wire to my Antec case only has 6 wires.

The connections on the board are labled

1 tpa1+ 2 tpa1-
3 ground 4 ground
5 tpa 2+ 6 tpa2-
7 +12v 8 +12v
9 no pin 10 ground

The lead wire from the Antec case has 6 wires labeled

1 tpa + 2 tpa -
3 tpb + 4 tpb -
5 vp 6 vg

So there is 3 connection missing. I probably can disregard two grounds. But then which 12v connection should I use and which ground should i use?

thanks in advance

It seems to me that you should disregaurd pins 10,8 and 4. For the poser and ground it really doens't matter as they only provide power. All 12v connectors are inevitably attached in your psu as are the ground. So if it were just me(wich it is so far) i would connect as follows:
1tap - 1tpa1
2tpa - 2tpa1
3tpb - 5tap2
4tpb - 6tap2
5vp - 7 +12v
6vg - 3 ground

EDIT: though looking at one of mine it is definatly matching the 9 pin design.
