So, almost everything working now, mostly thanks to you (!!)
So now I have been booting regularly, except when I enable Thunderbolt, and then I get a OCB Image failure. That's okay, as I just don't use TB on this machine much (actually almost never).
At one point, ALL of my USB drives would not work (with the exception of the ASMedia ones). I recreated a new USB Map from Hackintool, which was just a guess, because none of my builtin USB drives would respond at one point, so I couldn't do the "insert a USB 2 drive into each port...." because they were all just dead.
On the Insanely site, I am seeing a lot of folks having trouble with USB ports which they claim are being fixed by upgrading to new releases of OC 074....Hmm....
So, here's my current EFI, which is working and pretty close to final, which might be of use to someone......thanks again!
