i've changed my motherboard from a gigabyte x58 usb3 to a ud5 for the sata 3 using 2 w/d 640 6 g/s hard drives...the problem i'm having is in the manual it says enter the bios and set the ich sata control mode to raid(xhd) then save and reboot then after the post memory test begins look for a message which says "press <ctrl-l> to enter configuration utility"....i dont get this option, theres no message like this.. what i'm doing wrong...my set up is m/b x58a-ud5, i7 950 chip, gtx 570, ddr3 1600,h/drives 1.5 tb seagate. x2 640 w/d, titan fr cooler....thanks
