A DEX PS3 is a PS3 that is changed to (or is from factory) a developer machine. And we are talking about DEX firmware here that won't run on a standard PS3. To convert your PS3 to DEX you need to change some things using Linux on the PS3. It isn't an easy task.
So why go into all the converting trouble after installing Linux if the only thing to do is changing your Mac address using the same Linux? You can find the info here in the forum how to change your MAC address and how to go online again....
