Page 13: Installing Cables And Connectors
2.5 Installing Cables and Connectors 2.5.1 Speaker Connector Installation (J45) Your S1680S board provides a 4-pin header to connect the speaker. The speaker is connected to pins 24-27 of J45. (Refer to Page 10 and Page 11 for detailed information.) 2.5.2 Hardware Reset Switch Connector Installation (J45) The RESET switch on your case's display panel provides you with the HARDWARE RESET function which is the same as power on/off. - Page 14 However, we do not recommend that you flash the onboard BIOS. This procedure should only be done by a qualified technician or a Tyan technical support engineer. J33 determines which type of Flash EPROM is used. This jumper has been set to match the onboard BIOS chip.

Page 15: Dram Installation
2.6 DRAM Installation The S1680S uses a 64-bit data path from memory to the CPU which will accommodate up to 1GB 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 avail- able memory configurations. -

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... -
Page 17: Cpu Installation And Removal
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. -

3.4 Installation and Removal of the Pentium II Passive Processor Pentium II Passive CPU Module (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) Heat-sink Lock (x1) - Page 20 CPU, the motherboard, and/or the CPU socket. 2. Slowly press down on the CPU module until the CPU locks into place. A click will be heard when the CPU is locked securely into the module. S1680S-001-02 http://www.tyan.com...
- Page 21 3.4.4: Installation of the Heat-sink Heat-sink Lock Lock 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. A clicking sound will be heard when the lock is securely fastened to the Heat-sink mounting bracket.

Page 26: 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.
