When I pulled the cd/hard drive cage out, off popped the card reader cable, now I can't find where it goes! There doesn't seem to be any reference to it in the manual. I searched with google, read page after page for over two hours. Anyone know where on the motherboard this 5 pin female plug goes? There's a JM644 plate on the front left with two of those connectors, but is either one of those correct? Again, there's no mention of either in the manual.
