Pretty sure it's a 1.0 It has a fan on the graphics chip. All the traces seem to match the 1.0/1.1 pictures. The MFG date is Aug 22 '02.

From what your describing it now sounds like your D0 is connected properly. The only other thing I could suggest is that perhaps your grounding pin has a weak connection? The Chamelon relies on Pin 2 to ground D0 and so alot of time even if you have a conenction on Pin 2, it may not be strong enough to ground D0.

When I first installed my first Chameleon I experienced a similar problem to yours and after reading this excellent tip from dzv, it turned out that even though I had a connection on Pin 2, it wasn't strong enough to ground D0 and therefore would not work.

I resoldered the pin until I got zero resistance and then the Chameleon booted perfectly.
You can test to see if this is your problem without removing the motherboard by adding a second wire to D0 or to Pin 2 and grounding it to the screw on the motherboard to see if that resolves your problem.

Worth a shot.

I had the exact same problem, and came to the same conclusion as Flagg, tho I couldn't EVER get it soldered well enough to consistantly boot. I ended up hard wiring BOTH d0 and the ground pin on the chameleon directly to a ground screw. Works perfect now.

Good luck.

Flagg Thanks for the link.

I've read through the thread that Flagg linked to. If I had another connector for my X2lite I'd try it on this box.

I guess I'm going to have to ground Pin 2 and see what happens.

Hi All

I just noticed that "terrobyte" quoted :

It's usually ok for solder to be touching a track because the tracks are under a thin layer of protective plastic. As long as you don't burn the plastic off from the tracks you should be good.

This statment alas is incorrect as the motherboard is NOT coated in a layer of plastic, but a varnish substance that is kinda like nail polish.

Hey let us know how it works... I'm wondering if this is a trend for chameleon chips. My friend had the same problem and the only way he could get it working was grounding it directly as well.

It's not a trend for the Chemeleon chips, it's a trend for people not soldering correctly.

Pin 2 (ground), Pin 6 (5v), and Pin 9 (3.3v) require more heat (or more sustained heat) to solder correctly.

Read my thread about it here:

Way ahead of you dzv!

joehdtv,

I'm assuming by your lack of updates that your problem is now resolved?

Just wondering what the final fix turned out to be.

Unfortunately not. I had another modchip on the way (X2.2 Pro) so thouht I would try it to see if it worked before pulling the mobo for the 5th or 6th time.

Since it didn't work (FRAG) I know my problem is not pin2 since the x2 grounds to a screw. I will pull the mobo in the next day or two and resolder Pin 9 and check the others.

I'll post an update when I get it figured out.
