what i did was flashed the bios via http wtih a 4mb bios based on 4981.06. (the instructions said to make sure it was a 4mb bios) when i boot up to the xchip screen it says the bios is version 1.1. the chip flashed properly and i can get into avalaunch and run my games no problem. i havent been able to assign a button to disable the chip at boot. holding start when booting does not take me to the config screen, i need to set pin 2 to on via the external switch in order to get there. when i select the original xbox bios i dont get the option to assign it to a button, the screen flashes and goes back to the original menu. sorry if this is confusing, not an expert at this. appreciate the response kryxan. i have xbox version 1.0.
