On the first 1.5 XBIT chip I got the crappy connector broke off before I coult try it out. Because of this I couldn't program the chip. Now I have a new chip and conector. The programming in windows XP goes fine. Somethimes when I verify the data I get an error. But if I boot up the xbox the led on the connector turns on, but I keep getting the standard xbox bios. I have tried several biosses and refitting and cleaning the pogopins. Nothing works.
