  • Page 17: Dram Installation

    2.6 DRAM Installation The S1682D uses a 64-bit data path from memory to the CPU which will accommodate up to 512MB 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.

  • Page 18: L2 Cache Memory/Sram Memory

    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. S1682D-001-02 http://www.tyan.com...

  • Page 19: Cpu Installation And Removal

    Chapter 3: CPU Installation and Removal Pentium II (233 through 300MHz) and Pentium Pro Processors (150 through 200 MHz) can be used on the S1682D. Please refer to section 2.3 for the correct CPU jumper settings for your board. Although the S1682D motherboard is designed as a dual CPU system, it will also function with a single CPU.

    3.4 Installation and Removal of Pentium II Passive Processors (Unlike Active Processors, Passive Processors are not equipped with cooling fans. Passive Processors are equipped with heat sinks instead.) Each CPU package should also contain the following: CPU Retention Module (x1) Heat-sink Retention Bracket with mounting locks (x1) Mounting Attach-mounts (x 2)

  • Page 23 3.4.4 Installing Heat-sink Locks The heat-sink lock has 4 notches which will correspond to the 4 pins on the heat-sink mounting bracket. Gently slide the lock between the heat- sink onto the heat-sink mounting bracket until both sides of the lock are firmly secured.

  • Page 24: T Roubleshooting

    1. Check to determine if SIMM modules are improperly installed. 2. Make sure that different types of SIMMs have not been installed in the same bank. (eg. a mixture of 265KB x 9 and 1 MB x 9) S1682D-001-02 http://www.tyan.com...
  • Page 25 3. Determine if different speeds of SIMMs have been installed in the same or different banks, and the BIOS setup is configured for the slowest speed of RAM used. It is recommended to use the same RAM speed for SIMMs in different banks. 4.

  • Page 29: Bios - Speaker Beep Codes

    Chapter 6: Speaker Beep codes All Tyan motherboards come with a BIOS feature called "beep codes". What these do is inform you (the user) about potential problems in your configu- ration. These errors can occur during POST (Power On Self Test), which is performed every time the system is powered on.
