When the computer system is On, the Green LED will light up. If the system is on stand-by mode, the Yellow LED will light up. Whenever there is an incoming message, the LED will flash on and off. Soft Power Connector The Soft Power Connector is located on pins 6 and 8 of jumper block J3. Pressing the Soft Power Button will turn the sytem on and off.
3. Installing Memory Since TYAN boards are manufactured with performance in mind, you should use add-in components that match. Some DIMM modules may seem to be high quality because of name or feel but that does not guarantee real-world usability. Some cheaper or OEM memory may have brand-name components, but they may contain inferior or substandard parts which do not meet the critical tolerances our products require.
Chapter 2 Board Installation Figure 2-3 *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 2-3 above shows how to sit the DIMM into its slot.
INSTALL Figure 2-4 *The image above is used to illustrate a concept and may not represent the actual image of your motherboard. Some details of memory installation: • The mainboard supports 32MB, 64MB, 128MB SDRAM modules. • PC-100 DIMMs are required if CPU bus speed is at 100MHz • SDRAM, Parity, and ECC (using Parity memory) memory is supported. Unbuffered RFU Buffered 168-pin DIMM Figure 2-5 Cache Memory The Trinity ATX has 1MB (or 2MB) of onboard pipeline burst SRAM. This SRAM cannot be upgraded.
Chapter 2 Board Installation 4. Installing the CPU and Cooling Fan Socket 7 processors (see Specifications on page 5) can be used on the Trinity ATX. Please refer to page 14 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. • Before the CPU is installed, the mainboard must be placed on a flat surface.
INSTALL Figure 2-8 Locate the cooling fan connector (e.g. CPU Fan, Fan1) on the motherboard. Plug the CPU’s cooling fan cable into the cooling fan connector on the board. There will be a plastic clip assembly similar to that of the ATX power connector that will force you to connect the fan cable correctly (see Figure 2-8 above).
Chapter 2 Board Installation 5. Connecting IDE and Floppy Drives The colored stripe on a ribbon cable should face toward the keyboard connector. In Figure 2-9 on the previous page, you can see how the IDE cables should look when they are connected to your hard drive. Notice how Pin 1 (denoted by a red stripe) is connected so that it is next to the power connector of the drive. The primary IDE connector is black; the secondary IDE connector is white.
Figure 2-11 INSTALL Connecting Floppy Drives Pin 1 on the floppy cable is usually denoted by a red or colored stripe down one side of the cable (see Figure 2-11 on the following page). Most of the current floppy drives on the market require that the colored stripe be positioned so that it is right next to the power connector. In most cases, there will be a key pin on the cable which will force you to connect the cable properly. Drive A: is usually attached to the end of the cable with the twist in it.
Chapter 2 Board Installation Figure 2-12 Figure 2-13 Figure 2-13. Make absolutely certain that you do not miss any pins, because if you do you will void your warranty and cause damage to yourself or your motherboard when you turn the system on. After connecting the power, make sure the connector is seated firmly into its socket so it will not become loose or fall off when the computer is jostled or moved. Note: Tyan recommends using one that conforms to industry standard revision 2.01. 7.
you do this. When plugging the card in, especially when installing long cards, try to push the entire card in at one time. Don’t 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. • Make sure that the cards are seated securely into the slots. • Before turning on the system, make sure no cards are touching.
Chapter 2 Board Installation joystick port. It is fast enough to support video transfer, and is capable of supporting up to 127 daisy-chained peripheral devices. Connecting Com and Printer Ports 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.
with the mere 132MB/s (at 33MHz bus speed) that you get with the PCI bus. Q: Does my operating system support AGP? A: Currently, only Windows 98 and Windows NT 5.0 will have built-in support for AGP. Some AGP cards require Windows 95 OSR2.1 or a special driver from Intel. Please check with your graphics vendor for more details. Q: How do I identify Pin #1 of a 3-pin jumper? A: There should be a small numeral 1 silkscreened on the board in white next to pin 1.
Chapter 2 Board Installation The "viareg" folder is for "VIA Power Management Controller" and "VIA PCI to USB Universal Host Controller". NOTE: this driver is for Win95 users. There are no drivers for WinNT 4.0. No need to install for Win98 users. The "virq13 or virq11" folder will install "VIA PCI IRQ Routing Miniport Driver". NOTE: Enable "OnChip USB" in BIOS Chipset Features setup menu and Enable "Assign IRQ for USB" in PNP/PCP Configuration Setup menu.

Chapter 3 chapter 3 BIOS Configuration BIOS Configuration Introduction to Setup This manual describes the Award EliteBIOS Setup program. The Setup program lets you modify basic system configuration settings. The settings are then stored in a dedicated battery-backed memory, called CMOS RAM, that retains the information when the power is turned off. The EliteBIOS in your computer is a customized version of an industrystandard BIOS for IBM PC AT–compatible personal computers.
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.). The BIOS launches the operating system and hands control of system operations to it. During POST, you can start the Setup program in one of two ways: 1. By pressing immediately after switching the system on, or 2.

Setup Variations Not all systems have the same Setup. While the basic look and function of the Setup program remains the same for all systems, the appearance of your Setup screens may differ from the screens shown here. Each system design and chipset combination require custom configurations. In addition, the final appearance of the Setup program depends on your system designer.

Chapter 3 BIOS Configuration hard drive types, such as SCSI drives. Note: We recommend that you select type auto for all drives. The BIOS can automatically detect the specifications and optimal operating mode of almost all IDE hard drives. When you select type auto for a hard drive, the BIOS detects its specifications during POST, every time the system boots. If you do not want to select drive type auto, other methods of selecting the drive type are available: 1.

You should then run an anti-virus program.
Enabled assigns physical drive B to logical drive A, and physical drive A to logical drive B. Boot Up Floppy Seek When Enabled, the BIOS tests (seeks) floppy drives to determine whether they have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720 KB, 1.2 MB, and 1.44 MB capacity all have 80 tracks. Because very few modern PCs have 40-track floppy drives, we recommend that you set this field to Disabled to save time.

Doze Mode After the selected period of system inactivity (1 minute to 1 hour), the CPU clock runs at slower speed while all other devices still operate at full speed. Suspend Mode After the selected period of system inactivity (1 minute to 1 hour), all devices except the CPU shut off. ** PM Events ** A power management (PM) event awakens the system from, or resets activity timers for, Suspend mode. You can disable monitoring of common interrupt requests so they do not generate PM events.
Chapter 3 BIOS Configuration Primary Secondary The system wakes up fully when it detects IRQ activity. The system does not wake up, but the interrupt request is processed. Secondary interrupts are typically housekeeping devices needed to maintain the system while not requiring the use of the rest of the system resources. For example, IRQ8, the RTC Alarm, is configured as Secondary by default. Another example might be a network adapter continually polled by the network.

Appendix 1 Appendix 1 Glossary 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 computer’s devices. Devices not in use can be turned off, reducing unnecessary power expenditure. AGP (Accelerated Graphics Port) is a PCI-based interface which was designed specifically for demands of 3D graphics applications.
Bandwidth refers to carrying capacity. The greater the bandwidth, the more data the bus, phone line, or other electrical path, can carry. Greater bandwidth, then, also results in greater speed. A BBS (Bulletin Board System) is a computer system with a number of modems hooked up to it which acts as a center for users to post messages and access information. The BIOS (Basic Input/Output System) program resides in the ROM chip, and provides the basic instructions for controlling your computer’s hardware.
Appendix 1 Glossary Closed and open jumpers Jumpers and jumper pins are active when they are On or Closed, and inactive when they are Off or Open. CMOS Complementary Metal-Oxide Semiconductors are chips that hold the basic start-up information for the BIOS. 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).
tion about Plug and Play devices in the system BIOS. This information helps properly configure the system each time it boots. 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.
Appendix 1 Glossary Latency is the amount of time that one part of a system spends waiting for another part to catch up. This is most common when the system sends data out to a peripheral device, and is waiting for the peripheral to send some data back (peripherals tend to be slower than onboard system components). NVRAM ROM and EEPROM are both examples of Non-Volatile RAM, memory that holds its data without power. DRAM, in contrast, is volatile.
PnP is an acronym for Plug and Play, a design standard that has become ascendant in the industry. Plug and Play devices require little set-up to use. Novice end users can simply plug them into a computer that is running on a Plug and Play-aware operating system (such as Windows 95), and go to work. Devices and operating systems that are not Plug and Play require you to reconfigure your system each time you add or change any part of your hardware.
Appendix 1 Glossary operate normally. UltraDMA/33 is a fast version of the old DMA channel. UltraDMA is also called UltraATA. Without UltraDMA your system cannot take advantage of the higher data transmission rates of the new UltraATA hard drives. 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.
