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. Your 1684S/SA has a built-in VRM onboard. 2. 9 Peripheral Device Installation Install the motherboard after you have checked all of the jumper settings. Also be sure to check all connectors thoroughlyand read the technical manuals that come with your peripheral cards before you install your add-on peripheral 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 and On/Off Switch The system is configured for a standard ATX power supply. The ATX connectors can only be plugged in one way and should install easily.

Please refer to section 2. 3 for the correct CPU jumper settings for your board. The S1684SA board provides a slot for the Pentium II Processor. (Refer to the layout on Page 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 it's power cable to the cooling fan connector 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 and Key Pin S1684S/SA-001-02 19 Retention Module 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.
