Dell E6400/6500 research thread in E6xxx Posted March 13, 2012 · Report reply I just got an e6400 (waiting for it to be delivered) and want to install Lion onto it. Since there is not an E.D.P. and bootpack for the e6400 which is the best way to install and configure Lion? Mariusz posts are fantastic, but for a noob like me I like step by steps. dafob's step by step here is good but I want to use the Lion app that I purchased. So I've created the USB stick and not put anything else in it. Would the correct way be to copy Mariusz's dsdt.aml to /Extra, install Chameleon, install the applicable kexts from Mariusz's 0EDP.kext pack (not exactly sure how -- I have used multifail before and I have used kext wizard but have not install kexts any other way)? What exactly does the E.D.P. do? Regarding the bootpacks, are they basically a dsdt and other kexts that help to boot each specific Latitude model? Can you use the D630 bootpack and E.D.P. with an e6400? Thanks for your help! CP Read this post regarding boot pack.
