Ok so I have run into something a little odd. When I power on the PC and press CNTRL + M to enter BIOS, I go into the Marvell Bios, and not into the bios I want to go into. I am not getting any error codes or anything else out of the ordinary. I just can't access the x79's bios. Not sure what my next steps here should be. Parts list below. I've tried booting in all 3 possible bios selections. The first 2 won't post, the third will show me the X79 DARK flash screen and allow me to press CNTRL + M or Space. Any help would be greatly appreciated because I'm really scratching my head on this one.
CPU - Intel 4960x
MBO - EVGA X79 DARK
GPU - GTX TITAN x 3 (SLI)
