Ok I just upgraded to the i5 2500K. So here is the process to get this board GA-H61M-DS2 v.2.2 up and running. 1) Install using the Unibeast 1.5.2 method found on this site. Use boot flag PCIRootUID=0 if using an NVidia card for both install and first boot. (I am using a GeForce 9800 GT 1GB) 2) Now, you can use the DSDT file attached to this post. Make sure to put it on your desktop. I scoped google and used a patch from Olarila for a similar board so its not PERFECT but gets the job done (GA-H61M-S2V). 3) Run Multibeast and choose the following: USER DSDT; System Utilities; Unified Device Injector ALC8xxHDA; Patch AppleHDA ALC88b/887 v100302 (also make sure you install the kext from this post (Toleda is the man!) before you reboot - this will give you onboard audio - http://legacy.tonymacx86.com/viewtopic.php?f=16&t=59061&start=140 4)Install 3rdPartySATA & TRIMEnabler (if you have a SSD HD, if not then skip this) 5)AppleRTC and Patch AppleIntelPowerManagement for 10.7.4 (you may not need this for sleep if you can boot native) 6) On Board LAN is Realtek 8111 so install Lnx2Mac's RTL81xx Ethernet Kext (helps you get App Store) 7) Choose SSDT if using an i5 or i7 processor Choose iMac 12,1 as your profile I am working on getting sleep and mirroring with AirPlay since I have an HD3000 processor. Hopefully more to come on that. Also you may not need the DSDT file for this board since it uses the UEFI BIOS - but I find my system runs a little smoother with DSDT than with EasyBeast. Also in the BIOS make sure you enable Turbo at 34 and EHCI is set to enabled. A ton of thanks to SAMISNAKE (DSDT Editor tutorial), TOLEDA (ALC8xx Master) and of course TonyMac & MacMan - Another Donation is OTW!
