you should be able to update any "past 02" board with this kit, ***iirc****
EDIT says right on it 02 03 04 to 2005 update kit
good question on calling the techline, that mightve been just to setup the network krap which no longer exists anyways, one of our operator members could probhably tell us.
i wonder what cable you need? and if you update the board itself or (id assume) just the hard drive?
in reality, mabye with this kit, you could go buy a 05 xtra drive(xtra drive works with the regular 05 chip), install the chip, and viola you have o5?
You would need to send the board and the update in and pay IT a fee to manually update if they will still do that. I through out 40 of these 2 weeks ago.
