Needs hacking of this UEFI to have the option of AHCI.

Changing from RAID to AHCI seems a must for installation.The earlier version of UEFI can be hacked for changing to AHCI,and late versions was RSA signed,so needs reverse engineering,a time consuming and difficult task.

This kext is from Mavericks DP6, set the layout-id to 0 (zero)

Hi, I have STA9205 too, whose codec is 0x838476a0.

which layout shall be in Yosemite?

Also shall I change it accordingly in the DSDT?

                    Return (Local0)
                }
            }

TO:(changes are in RED).

IT's now with a Nvidia gfx card,sometimes when after Apple logo,it gets dark screen with power on. Voodoo can do,but poorly.
