Ok, I've heard EEPROM too many times without knowing what it is.
I've heard about backing it up, and that does no good since, I don't know what it is.

Now, I'm not a complete noob, I understand what a BIOS is, I have a modded xbox, tweaked the evox.ini, made my own skin, etc.

Just what is a EEPROM though!?

someone just asked this a day ago. search =P it's not a concern unless you go on live.

check the faq, there is a good chance questions like this are in there
