I think there is something wriong with the chip...
I installed it header style, and the chip was dead.
I resoldered lkke 4 times... No lights...
Then ii moved the chip around annd it booted the cromwell bioos.. So It may eb the connection to the pinhheader I don't know...

Yeah, I remember somebody mentioned having to move the chip around (maybe it was you).  It would tend to indicate a problem with the socket on the chip, though it could be that moving the chip is also moving the pins to make contact in the holes.  But I wouldn't rule out the possibilty of a problematic socket.  Remember the 'pinch technique' for programming the MatriX...    dry.gif

I would tend to agree, however if you look at the cross section of the forums you will find that many users will have mad other mods that have and/or do work in the place of the Chameleon. The only point that is not common between the Chameleon and the other installs is the GND.

Yes, and I believe that supports my theory.  If the person has a X2 installed on a pin header, it's entirely possible that person never actually had a solid connection to the LPC point 2, but the X2 will still work because of the additional ground wire.  Without that ground wire, maybe that X2 won't work?

It's all still very much a theory, but I hope to hear some feedback from more people who have had or are having problems installing their Chameleon.

If that is indeed the case, and your theory is true, than a jumper on pin 2 to a ground point (case or screw, from the bottom of the MB) should ground the Cham better, and solve the problem.  Might be worth trying.

However, that just doesn't explain why the rest of us have had no problems installing the thing.  No extra jumpers needed.

I think the more likely diagnoses are still:

1) Bad chip, or even more likely

2) Bad soldering

dzv....very good post....I could have used that info last night....he he. I agree, it seems that the pinheader has to be soldered just right or the Chameleon will not even work at all(MS Dash). Mine would not work at first until it was lightly twisted. Then after adding more solder to the pinheader connections it worked....

Very interesting post dzv...

That was me that had (has) to twist the chip around, seemingly only to get the light to blink...it still boots properly when I don't twist it.  That's the question that's driving me nuts...should I keep messing with my solder job or leave well enough alone and not risk making the LPC connections worse?  I have no idea whether it's the socket on the chip or the LPC solder joints.  And if I knew it was just the blue light, I wouldn't care anyway.  When would I ever see it inside the box on the backside anyway(assuming I ever use software/bios that even utilizes it)?  I tried pushing the pin rows away from each other a bit to try to get a tighter connection within the socket but that didn't do anything (wonder if that's similar to the pinch method you're referring to)....

DZV: good theory, but if you want to make sure that you got a good groun (pin#2) just put you voltmeter to Ohm and test pin#2.

GrisGris: I don't know if you remember this post, but i guess the "twisting" the chameleon was some one else ideal? smile.gif

Anyway, if you ground d0 it should boot up in the LPC BIOS, but if your LPC Bios is bad, then frag ... or you have a Bad solder ...

Nice..wish I had known this when I was having d0 problems.

Neo..yeah, I remember that thread (it documents by problems well!), but, no, noone suggested that I twist the chip...I just did it out of sheer frustration!

Thanks for the info dzv!

I just got around to installing one of my Chameleons on a new 1.2, and no matter what I did the box always booted with the normal BIOS.

I searched the forums and after reading your tips I double checked all of my pin header connections with a multimeter.  Sure enough, my connection on Pin 9 was weak.  I removed the motherboard and resoldered pin 9.  I rebooted and boom, Chameleon booted right up.

Thanks again for the tips!  Saved me alot of frustration.
