i have installed the x-chip in my box with the solderless adapter for v1.6...i am using the latest 1.3 bios from xbins for 1.6 only (although they say from 1.4-1.6 only). i get all five led's at power on, plus the red led on the x-chip for the voltage...it starts up the MS xbox boot screen, but then just sits there and then pops up error 7 or 16, either way it is not booting up from the 3 different cd's that i use, that i know work on my other modded xbox. i have a matrix chip in my older 1.1 box and it works great, at least when it boots, it replaces the MS text at the bottom of the boot screen with executer2, is the x-chip suppose to be doing something like this so that i know that it is working? i did the nickel trick to get the pins spread out a bit, and that fixed the voltage LED problem i was having with the chip. but not sure what else to do from here, other than make a new hard drive on my other xbox first so that i know that it works and then place it in my new box. anyone please guide me from here, i spent many hours pulling my hair out on this...i wouldn't mind hard soldering, if i had all the complete specs on this.
