So this loks like the rules for playing on XBL:
1.) Don't sign on to XBL with mod chip on
2.) If your xbox has ever been used on XBL before, you must stay with that HD
and EEPROM combo.
3.)Using a previsouly banned gamerTag on a large HD will result in having the
xbox banned again. Must use banned GT on stock xbox HD's.
4.)If yoru xbox hads a large HD and has never been on XBL, then creating a new
gamertag will allow you to be on XBL safely (with modchip off).
5.)If you want to switch to a large HD on an xbox that has been on XBL before,
you will need to get a new EEPROM to go with the large HD.
Sound right?
