Installing the FCPGA processors: The P3TDLR has two 370-pin sockets, which support single or dual Intel Pentium ® III FCPGA 500 MHz-1.26+ GHz processors and single or dual low power Pentium ® III processors at front bus speeds of 133 and 100 MHz. Lift the lever on the FCPGA socket and insert the processor (with the heat sink attached) keeping the notched corner oriented toward pin one on the socket. Make sure the processor is fully seated in the socket and then close the lever. You can also install a single processor on the motherboard without changing any jumper settings. (See Figure 5-4 for views of a 370-pin FCPGA socket before and after processor installa- tion.) 2-5
