THANK YOU!! This is my first time modding an Xbox and between the walkthrough posted by CAP69 and this trouble shooting guide, My Xenium Ice chip looks to be working great. I was getting the red LED on my chip when the xbox booted up and the machine would boot to the default dashboard. I never lost the red LED. I opened the box back up and re-cleaned the LPC points on both the solderless adaptor and the mobo, as well the the D0 point on the mobo and conector hook. Reassembled the whole thing and tried again. SUCCESS!!

looks as if the cleaning did in fact work. Thank You! Oh yeah, working with a V 1.0 machine.
I also noticed that the end, away from the screw, of the solderless adaptor had a little play, up and down, on the board. I have the black adaptor. It appears that the little play that was there has no affect on the opperation of the chip. I hope!!
But thak you again for this thread, without it I would be sitting here steeming!!
