Simple XBOX Mod Questions!

[Gurm]

Ok, here we go.

1. I am experienced in mod installing. I've done PSX, PS2, Dreamcast, etc. So I'm not afraid to open things up and use extreme heat to melt the motherboard if need be (*grin*).

2. Which MOD chip for XBox is generally considered best in terms of NOT messing the console up or causing bizarre changes?

3. Switchable mod chips - do the switches come with the chips (and are there instructions) or is that something the installer has to do?

Basically I have a neighbor who wants his box modded but does NOT want to mess it up or lose his online privileges. And the information out there is VERY confusing.

Help me out here!
