into the socket, turn the screw 180 degrees clock-wise to secure the CPU in the socket.
Note that the slot on the screw aligns with the lock and unlock legend on the case of

PCI Express* (x16)

The platform has one x16 lane PCI Express* Graphics slot and supports either x1 or
x16 modes. The slot is wired "lane reversed" which connects the Intel
Express Chipset lanes 0 through 15 to lanes 15 through 0 on the slot. The Intel
945GME Express Chipset will internally un-reverse this wiring since its CFG9 power-on
strap is tied low.
