i moved my executor 2.6 from an 1.2 0r 1.3 xbox into a v1.0 xbox and i cant get it to work. iuse a xapter3 and all the leds are correct so i presume the connections are okay, is this a bios incompatabilty. the led flashes grenn three times as it trys to boot up then it flashes red and green. the bios i have on the chip is 4983.67. is theer another bios for the v1.0 xbox and how would i install it if i cnat even get the xbox to boot up and can only install by cd or dvd.
