this is the 3rd xbox ive put a x3ce in but i didnt do any of the software, flashbios, evox or the xbmc. i had a freind do it so now im ready to flash the chip and would like to be able to do this on my own. i want to make sure i dont lose the pre flashed 3.03 flashbios as some others have done. i have a v1.6b and get the flashbios blue screen with the switchs set to off,on,off,off which should be bank 5678. i will use the flashbios 3294 v1.6 plus (this is the correct one for my version of xbox?) now, what should the bank switchs be set to so i can always get back to the pre flashed 3.03 if something gets messed up? is there anything esle that ive missed also. thanks guys.
