Hey!
Are you thinking of Intel Smart Response? In any case, I don't recall Asus including that into their BIOS setup utility. You need to select "RAID" if it's available in BIOS. Save the change, exit, and then enter the RAID setup utility. See if you can create a RAID array then.
Can you take a picture of the "blue line with red dot details" and post it? I think I know what you're referring to (it sounds like RAID is already enabled in BIOS) but want to make certain.
