I installed EDP a few days ago because I had some problems with my new ssd unit, and built a configuration from the model database. It created a new /Extra folder with a new dsdt.aml file and made a backup of my old one. My problems with the ssd unit got solved, but the lan did not work any more. So, after struggling for a while, I put back the dsdt.aml I built before, and the com.apple.Boot.plist I had under /Extra.
With the latest EDP and my 2 old files, all seems to run ok now.
