cromat44 - Or, if it's not a physical switch like an Xecuter 2.3b, an OS based solution like the Xenium, where you can boot to MSDash, or pressing the eject button with a SmartXX.
Smasher9a - Yes, you'll get banned if you do it that way. You have to boot up to the OS menu to select the original BIOS - you can't go on Xbox Live if you go to MSDash through EvoX first.
jcautela - like I just said, it may not be in the form of a switch. But ALL never chips have an EASY solution to prevent Xbox Live bannings. And with the Anti-Live BIOSes, not getting banned is easier than ever
And to those suggesting keygens for eeproms, it's not a good idea in the first place, and something that would quickly become bannable here at Xbox-Scene.
