Heh, maybe you don't want Live now but down the road you may change your mind (Halo 2, maybe?). I opted for the hassle free way to mess with my Xbox. I bought the SmartXX chip that has an onboard OS which allows a little more flexibility and lets you fiddle with your xbox without any Bios loaded; stuff like FTP'ing, Formatting HD, flashing your bios through the IE browser, shit like that. It's a few more bucks than the popular X2 chips but I think it's worth it.
As for the d0, you should solder the alternate one on the bottom of the motherboard.. much easier.
If there are some of you in the West Coast that needs some modding, I'll be happy to do it!! ;p
