[. . . ] There are no L2 Cache Memory slots or SRAM slots on the board. 2. 8 VRM (V oltage Regulator Module) The CPU will program the VRM for the correct voltage needed. It also has a built-in Switching power supply. 2. 9 Peripheral Device Installation Install the motherboard after you have checked all of the jumper settings. Also be sure to check all connectors thoroughly and read the technical manuals that come with your peripheral cards before you install your expansion cards. If a PCI-Bus interface card is to be installed in the system, any one of the four PCI-Bus slots will support either a Master or a Slave device. 2. 10 Connecting the power supply The system is configured for a standard AT power supply. The AT connectors can only be plugged in one way and should install easily. S1680S-001-02 http://www. tyan. com 16 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. 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. ) Pentium II Slot Connector & Key Pin 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 motherboard. ) S1680S-001-02 17 Installing the Pentium II Active CPU 5. When the Retention Module is securely installed, you are ready to plug the CPU into the Retention Module. Make sure that the CPU's Cooling Fan is turned away from the I/O connectors before you plug the CPU into the CPU module. Retention Module 6. Press firmly on the CPU until you hear a "click".
