@MILAN0 - You should find lots of information for your board here:
How can I help me with your work done to install SL on my EP45-DS4?
Having held off from posting for too long, I want to say a big thanks to blackosx for this guide and all the hard work you have put in developing your PDF series and Support materials all with such eye for detail and with an extremely professional presentation. They are a pleasure to use.
The comments and discussions on this thread have helped so much and been very informative. It guided me through all the setting up and tweaking of my OSX86 machine that now runs so beautifully. Please forgive my ebullience
Well done with your installation, thanks for your kind words and for reporting back your success. I fully understand your ebullience.
You might be interested in this new topic by mozodojo where he has managed to re-work the FakeSMC.kext and plugin's to load from /Extra/Extensions allowing us to leave the /S/L/E untouched again (apart from those of us, me included, using the ALC888 onboard audio). I have it installed and can say everything is working well except for an issue with the GPU FAN sensor but as it's still in development I won't add it to the guide/support files just yet.
The final icing on the cake was the recent Cartri's BIOS flash and the addition of the new FakeSMC+plugins, thanks to the Guys developing these! referenced in your (Part 7 - What's New v1.4.1.pdf) many thanks for that information.
