So tonight my xbox kicked the bucket. I went and got it back from my brother and as i go to boot it up it no longer boots, just three failed power ups and then green/red blinking. So i've been searching for info on this so i can hopefully fix it for halo2 tomorrow night. I think it is a bios issue(the xbox isn't modded). My question is: Is it possible to replace the bios? Can i reprogram the chip with a bios image on the net? I have an eeprom programmer, my concern is whether and image i find on the net will work with a non-modded xbox.
