[. . . ] Close J52 by covering the pins of J52 with a jumper cap to short the circuit between the pins. By following the above procedures, the password and CMOS will be reset to BIOS defaults. (Refer to Page 12 for more information. ) S1684S/SA-001-02 http://www. tyan. com 16 2. 6 DRAM Installation The S1684S/SA uses a 64-bit data path from memory to the CPU which will accommodate up to 768MB of RAM. The motherboard supports FPM (Fast Page Mode), EDO (Extended Data Out), ECC (Error Correcting Code), and Parity 72-pin SIMMs. The following table shows some of the available memory configurations. Bank 0 4MBx2 8MBx2 4MBx2 8MBx2 4MBx2 16MBx2 16MBx2 32MBx2 64MBx2 16MBx2 32MBx2 32MBx2 64MBx2 128MBx2 64MBx2 128MBx2 128MBx2 Bank 1 none none 4MBx2 8MBx2 4MBx2 none 16MBx2 none none 16MBx2 32MBx2 32MBx2 64MBx2 none 64MBx2 128MBx2 64MBx2 Bank 2 none none none none 4MBx2 none none none none 16MBx2 none 32MBx2 none none 64MBx2 none 64MBx2 8MB 16MB 16MB 2MB 24MB 32MB 64MB 64MB 128MB 96MB 128MB 192MB 256MB 256MB 384MB 512MB 512MB total S1684S/SA-001-02 17 2. 7 Level 2 Cache Memory/SRAM Memory The S1684S/SA's L2 Cache Memory is built into the Intel Pentium II CPU. 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. S1684S/SA-001-02 http://www. tyan. com 18 Chapter 3: CPU Installation and Removal Pentium II (233 through 300MHz) and Pentium Pro Processors (150 through 200 MHz) can be used on the S1684S/SA board. Please refer to section 2. 3 for the correct CPU jumper settings for your board. 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. To attach the Retention Module, place the motherboard on a flat surface. 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. (Warning -- Do not overtighten the screws as you may damage the module and/or the motherboard. ) Installing the Pentium II Processor 5. When the Retention Module is securely installed, you are ready to plug the CPU into the Retention Module. [. . . ] 3.
