Dear lanyo,
Welcome to os x latitude!
After installing os x using myhack, we would recommend that you use generic Extra from the bootpack for your model from the menu above . After that, upon first start up, install and configure EDP 2.2. Don't forget to run myfix full mode (from myhack) on the system after installing EDP 2.2 before rebooting. This is very important for EDP 2.2. Otherwise you'll get a lot of weird KP.
When you get your internet connection working, we would recommend that you download and install the latest EDP 3.1 which is compatible with myhack. Look for the topic on it in the forum for instructions.
Cheers!
