do a TSOP flash.i just did mine and my xbox is 1.0 softmodded.and the TSOP flash worked great

.now i can get to work on a slimbox mod

.
i used a 256 bios instead of a 1MB just incase somthing went wrong i could still flash the other side of the tsop

and modchips have a higher chance to frag ur xbox than a TSOP flash...and best of all its free
