i just got my xbox modded with the xecuter3 by a professional installer. since they don't flash the bios, i have to do it. my question is doesn't the chip comes with it's own bios and what are the benefits of flashing it with the 1957 repack. also, if i decide to flash it with the new X3 bios, do i have to rename it to "bios.bin". also is it necessary to create a dummy bin bios for this chip. i'm so confused, any direction you can provide would be appreciated.
