[. . . ] Short J44 by covering Pin 1 and Pin 2 of J44 with a jumper cap and short the circuit between these two pins. Wait for 5 seconds, and then remove the jumper cap from J44. By following the above procedures, the password and CMOS will be reset to BIOS defaults. S1686S/D-001-02 15 2. 6 DRAM Installation The S1686S/D uses a 64-bit data path from memory to the CPU which will accommodate up to 1024MB of RAM. The motherboard supports FPM (Fast Page Mode), EDO (Extended Data Out), ECC (Error Correcting Code) or 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 32MBx2 64MBx2 128MBx2 64MBx2 64MBx2 128MBx2 Bank 1 Bank 2 Bank 3 none none 4MBx2 8MBx2 4MBx2 none 16MBx2 none none 16MBx2 32MBx2 32MBx2 32MBx2 64MBx2 none 64MBx2 64MBx2 128MBx2 none none none none 4MBx2 none none none none 16MBx2 none 32MBx2 32MBx2 none none 64MBx2 64MBx2 none none none none none 4MBx2 none none none none 16MBx2 none none 32MBx2 none none none 64MBx2 none Total 8MB 16MB 16MB 32MB 32MB 32MB 64MB 64MB 128MB 128MB 128MB 192MB 256MB 256MB 256MB 384MB 512MB 512MB S1686S/D-001-02 http://www. tyan. com 16 2. 7 Level 2 Cache Memory/SRAM Memory The S1686S/D's L2 Cache Memory is built into the Intel Pentium II CPU. There are no L2 Cache Memory slots or SRAM slots on the motherboard. 2. 8 VRM (V oltage Regulator Module) The CPU will program the VRM for the correct voltage needed. The S1686S/D has two built-in VRMs on board. Switching power supply circuitry has been designed into the motherboard as well. 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 add-on peripheral cards. If a PCI-Bus interface card is to be installed in the system, any one of the five 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. S1686S/D-001-02 17 Chapter 3: CPU Installation and Removal Pentium II (233 through 300MHz) and Pentium Pro Processors (150 through 200 MHz) can be used on the S1686S/D. Please refer to section 2. 3 for the correct CPU jumper settings. Although the S1686D motherboard is designed as a dual CPU system, it will also function with a single CPU. The S1686S/D board provides one or two slots for Pentium II Processors-(Primary and Secondary Slots - (2nd only on S1686D)). If only one CPU is used, the CPU should be plugged into the Primary Slot. However, when two CPUs are used (S1686D), these CPUs should be of the same speed and type. 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 Pentium II Boxed (Active) Processors (Note: Active Processors are equipped with cooling fans. When installing an Active CPU, you also need to connect the cooling fan cable to its connector. ) Installing CPU Retention Modules 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. [. . . ] Features The LM78 includes the following features: · Temperature sensoring · 5 positive voltage inputs · 2 op amps for negative voltage monitoring · 3 fan speed monitoring inputs · Input for additional temperature sensors · Chassis Intrusion Detector Input The software program-- LDCM (LANDesk Client Manager) is used as the LM78's drivers to accomplish monitoring computers' temperatures and voltages. The LDCM Drivers use the LM78 to monitor critical hardware components and enable remote sensing and diagnostics of the system Board. Thus, by implementing both National Semiconductor's LM78 and LDCM in the S1682D system, Tyan provides you with the best quality board possible on the market.
