Same situation here. My box had been messing around with me, fraggin and the such. Error 05 was the case, so I locked my hard-drive in one of the becoming rare occasions that I could get my xbox on. It was workin until I took my xbox back home with me and I guess it was sitting without power for about 4 hours. Bad times. Now I get error 16 when my modchip (X-Ecuter 2.2 Lite+) is off, and a frag with my modchip turned on. I cannot validate that the D.6 bios works as I have it loaded it on bank 2 of my chip and it isn't "bypassing" any time problem. I'm pretty much stuck as it is. My old harddrive has EvoX loaded on it and I'll still try that as a swapping option. I don't think that it is a dashboard problem though, since I have both the msdash and the evoxdash on my existing hd. Does anyone know off-hand what the original dashboard xbe was called? If anyone has the same situation as I do, please let me know your progress.
