Now let's see...
LGA1156 Lynnfield has on-die x16 2.0 PCIe for GPU and connects to the "SB"
by DMI, which is x4 PCIe 1.1 lanes. Through these 4 PCIe1.1 lanes, goes
the traffic of the Gb Eth, all SSDs/HDDs/ODDs, mice, webcam, external HDD,
other misc stuff; and on what's left over, this. Lol. DMI needs to die, fast.
