Good news, best and easiest install to date. Thanks all who worked on this!
GA-Z77X-UD5H
2x 650ti Boost with SLI - both working
Realtek ALC898 - Sound working
Atheros Lan - working, 2nd Intel not working yet. I've installed every driver (is this bad?)
First issue I had was I couldn't create the USB stick, it gave me the "Make sure neither "OS X install ESD" os "OS X Base System" are mounted on your drive". I figured it was the App Store downloader installer, rebooted and it worked like a champ.
Second issue was interesting: Did a clean install and multibeast with NO audio or Network options, just UEFI....rebooted and I had SOUND and NETWORK! wtf? Danced around a bit, then proceeded to use migration assistant from my carbon copy drive....checked it in the morning...NO AUDIO or NETWORK? hahaha.... ok.
Ended up redoing from scratch since it copied over a bunch of CISCO VPN and other stuff I really hate because it's strewn all over the system.
All is good now. Thanks again.
