Why do you need IP adress ? To communicate with Xbox and computer (PC or MAC).
To install Evolution X, it's more easy, you don't need to use a CD RW or DVD to flash modchip !
Smartxx OS is already ok to be on network !
You only need to write the good settings and Xbox is ready to receive files from your computer !
You only need an ethernet wire (RJ45).
Of course you need to configure your computer for network.
When everything is OK, power ON the Xbox
go on "config" menu
then "Network"
"IP adress"
""Enable Ethernet" must be select "On"
then "Subnet"
you can see this...
don't forget to "Save and Exit"
to save informations
IP adress will be appear on right bottom
If you don't want to write your IP adress manuelly, select "On" for "DHCP" and IP adress will be appear automaticly.
