I've purchased a ASUS Z97M-PLUS and successfully patched the BIOS to allow writting on MSR 0x2c bit 15 (see screenshot). I've managed to install Mavericks 10.9.3 with success, and:
After install I can boot through my USB stick and boot the local drive with "-x UseKernelCache=No'" and it works. From there, I've dropped SSDT.aml and placed it on /Extra in order to get CPU recognized (i5-4670 3.4Ghz). When I do this, my USB stops working and I believe that since I'm booting from the USB stick, it fails to successfully handle USB and everything stops there with a "Still waiting for root device". Passing arguments (Chimera) like rd=disk0s2 (confirmed, SSD) still fails.
So I'm kinda stuck here. Anyone can help (maybe DSDT patching, though it's UEFI)?
From here no options allow me to boot back even if -x.
