i hooked up my chip inside 3 xbox's. 2 where v.1.0 the other was v.1.0 sc now the first two i would get the same error. it would boot up, reset 3 times, then frag. that happened on both standard v.1.0 boxes. the third box (v.1.0 sc) worked. booted into the chip, and was fully functional. We verified the lpc ports were locked into place, the d0 was properly hooked up...but still both boxes errored out, yet the third one was operational. now i can boot the 2 boxes up normally, with no chip, and play games. so tell me, does anyone know if there is some conflict with early board versions? is there some sort of d0 issue?
