What's your question? It's very important to backup your eeprom, it is used to lock your hdd and if you don't use the eeprom that is on the mobo (the original eeprom) you won't be able to use your xbox again.
I have my EEPROM backed up twice. 1 time on a CD with other things and I have my full C: and E: drive (with EEPROM) backeup and burnt to DVD incase I run into problems.
