i have installed yosemite 10.10 on the hdd of 500 gb and tried a few combination whit multibeast for try make boot it;
all time i need write: -x -v DSDT=Null for make start it in same mode, if i no use one of them boot stop.
i no have changed nothing on the motherboard bios or setting etc etc....

whit safe mode the audio not work and the video some time lose quality for example when i open youtube and use full screen...
