    Installing CPU Retention Modules Installation of a Pentium II processor requires a CPU retention module, which is first secured onto the motherboard. Tyan offers a variety of retention mechanisms for the different CPU types. See Appendix 1 for options. Installation of SECC2 CPUs (Figuer 2-7 above) with the retention modules require a little more attention and care.

  • Page 106 ZIF socket Zero Insertion Force sockets make it possible to insert CPUs without damaging the sensitive pins. The CPU is lightly placed in an open ZIF socket, and the metal lever pulled down. This shifts the processor over and down, guiding it into place on the board. http://www.tyan.com...
