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 details.
To attach the retention module,
place the motherboard on a flat
surface. Locate the key pin on one
end of the Pentium II slot on the
board. Then carefully line up the
key notch on the retention module
with the key pin on the Pentium II
slot (the key pin on the Pentium II
slot indicates the correct
orientation of the CPU).
Drop the retention module (Figure
14 on the following page) down
over the Pentium II slot so that the retention module sits flat against the
motherboard. Tighten the screws in a clockwise manner to secure the module
to the board. Warning: Do not overtighten the screws as you may damage the
module and/or the motherboard.
Installing the CPU with Active Cooling
When the retention module is securely installed,
you are ready to plug in the CPU. Press down firmly
on the CPU until you hear a "click" (see Figure 15
on the next page). This clicking sound indicates
