! Important! important! Pleae note: In some versions of the S1854 board, there is an extra jumper setting (JP21) for CPU SELECTION. If you are using a Slot 1 Type CPU, please close the jumper, if your CPU is a socket please leave the jumper open. JP21(CPU Select) Warning: If JP21 is set to the incorrect CPU type, there will be no video display at Post. Please correct the jumper setting and reboot the system.
Chapter 2 Board Installation ! important! 1. Setting Jumpers 1-A. CPU Speed Settings (Jumpers JP10, JP11, JP12, JP13) There are two steps to set the CPU speed. First, set the clock multiplier with jumpers JP10 -13 according to the specification of your CPU using the chart below. After the system is ready to boot the BUS Speed is auto-detected. Presently all Celeron CPUs use a 66MHz bus speed. (Tyan does not recommend operating CPUs, memory, or PCI Bus at higher than rated speed.

Chapter 2 Board Installation 1-G Soft Power Connector The Soft Power Connector is part of jumper block J16. The Trinity 400 uses the chipset for power management, including turning on and off the system. If the Power Button Function option in the BIOS Power Management Menu is set to On/Off (which is the default), pressing the power button once after the BIOS has booted up will turn the system on and off.
1-K Power LED Connector Jumper D31 is a three pin power LED header that can be used if you have a 3 pin Power LED. Otherwise refer to panel connector J16 for 2 pin LEDs. 3 pin LEDs can still be used on J16 where pin 13 would be for the Ground pin. CMOS RTC Flash EEPROM The Trinity 400 uses flash memory to store BIOS firmware. It can be updated as new versions of the BIOS become available. You can upgrade your BIOS easily using the flash utility (see page 60). 2.
Chapter 2 Board Installation 3. Installing Memory Since TYAN boards are manufactured with performance in mind, you should use add-in components that match. It is highly recommended that the memory DIMMs are installed prior to connecting the power supply. Some DIMM modules may seem to be high quality because of name or feel but that does not guarantee real-world usability.
INSTALL Figure 2-5* *Note: The image above is used to illustrate a concept and may not represent the actual image of your motherboard. To install your DIMMs, line your module up so that the pins fit into the slot. There is only one way that your DIMM can fit properly. Make sure that the short row of pins is lined up with the short gap in the DIMM slot. Figure 2-5 shows how to sit the DIMM into its slot. To insert the DIMM, push down vertically on the module with even force, as shown in the photo.
Chapter 2 Board Installation Figure 2-6* *Note: The image above is used to illustrate a concept and may not represent the actual image of your motherboard. The Trinity 400 uses a 64-bit data path from memory to CPU and can accommodate up to 768MB of SDRAM. The 168-pin DIMMs (Dual In-line Memory Modules) must be of the 3.3V, unbuffered variety. The position of the notch in the SDRAM key position will tell you whether or not a DIMM is unbuffered (see the Figure 2-7 below).
Some details of memory installation: At least one unbuffered DIMM must be installed for the system to POST. The mainboard supports 32MB, 64MB, 128MB and 256MB SDRAM.
Chapter 2 Board Installation 4. Installing the CPU and Cooling Fan Socket 370 type Celeron processors (300 through 533MHz) and Slot 1 type Pentium II/III can be used on the Trinity 400. Please refer to page 15 for the correct CPU jumper settings for your CPU. Remember: The CPU is a sensitive electronic component and it can easily be damaged by static electricity. Do not touch the CPU pins with your fingers. You should be able to insert the CPU into the socket with virtually zero force.
Installing Slot1 Type CPUs Figure 2-9b Figure 2-9a *Installing CPU Retention Modules* Note: Tyan provides a variety of retention modules. For detailed installation procedures of your module, please refer to Appendix 2 located at the back of the manual. Figure 2-10 below shows a side view of a retention brace securing both sides of the SECC2 CPU. When both sides are properly positioned, press both braces against the sides of the CPU and carefully lift them over the CPU slot on the motherboard.
Chapter 2 Board Installation Figure 2-11 Line up the retention brace with the holes provided on the motherboard. At the same time, make sure the CPU is lined up with the CPU slot. Lower the CPU onto the motherboard. The mountings on the retention brace should fit through the holes of the motherboard and the CPU should fit into the slot. (See Figure 2-11). Secure the retention brace. The end result should look like Figure 2-12.
INSTALL Figure 2-13 Removing CPU When removing the CPU, pull lightly on the pegs sucuring the retention brace and remove the CPU and retention brace at once. This may require careful firm tugs to pull the CPU out of its slot. 5. Connecting IDE and Floppy Drives The colored stripe on a ribbon cable should face toward the battery on the motherboard. Make sure that Pin 1 (denoted by a red stripe) is connected so that it is next to the power connector of the drive.
Chapter 2 Board Installation Pin 1 Figure 2-14 *Note: The image above is used to illustrate a concept and may not represent the actual image of your motherboard. Some symptoms of incorrectly installed HDDs are: Hard disk drives are not auto-detected: may be a Master/Slave problem or a bad IDE cable. Contact your vendor. Hard Disk Drive Fail message at bootup: may be a bad cable or lack of power going to the drive. No video or beeps onbootup: usually means the cable is on back wards.
Some symptoms of incorrectly installed floppies are: Floppy drives are not detected: usually caused by faulty cables, backward cables, or a bad floppy or motherboard. Try another single floppy drive to verify the problem or try another cable. Also, check to see if the onboard floppy is enabled in the BIOS. Floppy Drive Fail message at bootup: the cable, floppy, or motherboard may be faulty. Try another cable or floppy drive to verify.
Chapter 2 Board Installation warning NEVER plug an ISA card into a PCI slot or a PCI card in an ISA slot. You will void your warranty and damage your system board if you do this. When plugging the card in, especially when installing long cards, try to push the entire card in at one time. Dont force one end of the card into the socket first and then the other. This will create a rocking motion between the card and the slot and it will damage the pins within the socket.
Mouse Figure 2-16 Figure 2-17 Connecting Com and Printer Ports Figure 2-18 warning Warning: When plugging in your keyboard and mouse, or when plugging anything into a serial or Com port, make sure that the power is off. Connecting these devices and ports while the power is on is called hot plugging, and may damage your system.Figure 2-18 above shows the ATX double row connectors on this board. The Com and Printer ports, as well as the other ports, are labeled.
Chapter 2 Board Installation 8. Connecting the Power Supply Tyan recommends using an ATX power supply that conforms to industry standard revision 2.01. The Trinity 400 motherboard comes equipped with one onboard power connector. Figure 2-16 below shows an ATX power connector. When plugging in the power connector, make sure that the plastic clip on the power connector is aligned with the plastic tab on the onboard connector (see Figure 2-17 below).
chapter 3 INSTALL BIOS Configuration Introduction to Setup ! important! The BIOS section of the manual is subjected to change without notice and is provided here for reference purposes only. The settings and configurations of the BIOS are current at the time of print, although they may not be exactly the same as that displayed on your screen. This manual describes the Award BIOS Setup program. The Setup program lets you modify basic system configuration settings.
Chapter 3 BIOS Configuration Starting Setup The Award BIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it through the poweron self test (POST). When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage devices (hard drive, floppy drive, etc.).

Appendix 1 Glossary ACPI (Advanced Configuration and Power Interface) is a power management specification that allows the operating system to control the amount of power distributed to the computers devices. Devices not in use can be turned off, reducing unnecessary power expenditure. AT was the original form factor of IBMs PC. ATAPI (AT Attachment Packet Interface), also known as IDE or ATA, is a drive implementation that includes the disk controller on the device itself.
Appendix Glossary data the bus, phone line, or other electrical path, can carry. Greater bandwidth, then, also results in greater speed. The BIOS (Basic Input/Output System) program resides in the ROM chip, and provides the basic instructions for controlling your computers hardware. Both the operating system and application software use BIOS routines to ensure compatibility.
The COM port is another name for the serial port, which is so-called because it transmits the eight bits of a byte of data along one wire, and receives data on another single wire (that is, the data is transmitted in serial form, one bit after another). Parallel ports transmit the bits of a byte on eight different wires at the same time (that is, in parallel form, eight bits at the same time).
Appendix Glossary Firmware is low level software that controls the system hardware. Form factor is an industry term for the size, shape, power supply type, and external connector type of the PCB (personal computer board) or motherboard. The standard form factors are the AT and ATX, although TYAN also makes some Baby-AT boards. A Global timer is an onboard hardware timer, such as the Real Time Clock. Handshaking is a form of encryption.
NVRAM ROM and EEPROM are both examples of Non-Volatile RAM, memory that holds its data without power. DRAM, in contrast, is volatile. OEMs (Original Equipment Manufacturers) like Compaq or IBM package other companies motherboards and hardware inside their case and sell them. The parallel port transmits the bits of a byte on eight different wires at the same time (that is, in parallel form, eight bits at the same time). PCI stands for Peripheral Component Interconnect.
Appendix Glossary reconfigure your system each time you add or change any part of your hardware. The term RAM (Random Access Memory), while technically referring to a type of memory where any byte can be accessed without touching the adjacent data, is often used to refer to the systems main memory. This memory is available to any program running on the computer.
Universal Serial Bus or USB, is a versatile port. This one port type can function as a serial, parallel, mouse, keyboard, or joystick port. It is fast enough to support video transfer, and is capable of supporting up to 127 daisy-chained peripheral devices. VGA (Video Graphics Array) is the PC video display standard. V-SYNC controls the vertical properties of the monitor. ZIF socket Zero Insertion Force sockets make it possible to insert CPUs without damaging the sensitive pins.
Appendix 2 Appendix 2 Retention Module installation Retention Module Installation Installing SECC2 CPUs -Option 1 The following are alternative methods of installing the CPU and retention module to that of chapter 2. On both sides of the SECC2 CPU reside the lower tabs of the aluminum heat sink (see Figure A below). These tabs should snap into the retention module. Currently, the retention module recommended for securing the SECC2 CPU is included in the motherboard package.
Line up the pegs of the retention brace with the holes provided on the motherboard. Secure the retention brace by pressing firmly on the pins until they lock into the motherboard.(Figure B) Figure B Line up the CPU with the slot and slide CPU into the module from the top until you here a click. (See Figure C). The end result should look like Figure D on the following page.
Appendix 2 Retention Module installation Figure D Figure D above shows a properly installed SECC2 CPU using the retention module. Note the direction of the CPU fan and the way in which the cable is connected. Remove CPU Release the CPU from the retention module by gently bending the two ends of the retention module away from the CPU. With the module out of the way, pull the CPU out of the slot This may require careful firm tugs to pull the CPU out of its slot. . http://www.tyan.
Installing SECC2 CPUs - Option 2 Another method to secure an SECC2 CPU is by using the Universal Retention Module (also provided by Tyan). The universal retention module is designed to accommodate most versions of the Pentium Celeron CPUs. Included in this solution is an overhead clip to lock the CPU into its slot along with the side universal braces. See Figure E (above) for the universal retention Top Clip Side Braces Figure E module components.
Appendix 2 Retention Module installation Figure H* Tab Make sure the lower lip of the overhead clip is oriented towards the Tab opposite side of the CPU fan (see Figure I left). Lowered lip Removing CPU - Removal of the CPU is basically the reverse order of the installation steps. First remove the overhead clip. You need to push BOTH side lock tabs (see Figure I above) towards the center of the CPU in order to unlock it from the side braces.
