These are pictures from the MID (Mobile Internet Device) board, rev D4. In a Smart Book (netbook, tablet only, or MID only), this board is mounted into the MID. In a Touch Book (netbook or tablet only), this board is slightly different (see comments below) and directly plugged into the tablet board. In any case, it holds the core computation system.
