Hey, I understand that if a person doesn't install a mod chip, the bios can be flashed and afterwards a dashboard needs to be installed. Does option 7 of Slayer 2.5 [Flash XBOX v1.0-1.5 On-Board TSOP or Mod Chip] accomplish that? Or do you still have to open up the xbox to flash its bios, regardless of having Slayer 2.5 and making use of its option 7? Please let me know, I'm trying to learn about bios/dashboard/flashing. Thanks!
