Cpu Installation And Removal; Installing The Pentium Ii Boxed (Active) Processor - TYAN TAHOE AT Manual

Chapter 3: CPU Installation and Removal
Pentium II (233 through 300 MHz) and Pentium Pro Processors (150 through
200 MHz) can be used on the S1680S board. (Please refer to section 2.3
for the correct CPU jumper settings for your board.) The S1680S board
provides a slot for the Pentium II Processor. (Refer to the layout on P 10.)
Caution!! The CPU is a sensitive electronic component which can be easily
damaged by static electricity. Do not touch the CPU contacts with your fingers.
3.1 Installation of the Pentium II Boxed (Active) Processor
(Note: An Active Processor is equipped with a cooling fan. When installing an
Active Processor, you need to connect its power cables to the cooling fan
connectors located on the board.)
Installing the CPU Retention Module
1. Installation of a Pentium II Active Processor requires a CPU
Retention Module, which is first secured onto the motherboard. (Refer to
the motherboard layout on Page 10.)
2. To attach the Retention Module, place the motherboard on a flat
surface.
3. 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.)

4. Drop the Retention Module down
over the Pentium II Slot so that the
Retention Module seats 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 mother-
board.)
