Page 8: Chapter 2: Board Installation
Chapter 2: Board Installation Installation You are now ready to install your motherboard. The mounting hole pattern of the Trinity i845 matches the ATX system board specifications. Your chassis should support a standard ATX motherboard form factor. How to install our products right… the first time The first thing you should do is read this user’s manual. -
Page 9: Front Panel Connector
Your chassis will usually come with connectors to install onto the motherboard, such as HDD and Power LEDs. The Front Panel Connector (J80) has been implemented for such purposes. Infrared (IrDA) * optional feature available on some Trinity i845 models http://www.tyan.com... -

Page 11: Fan Connectors
The FAN connectors FAN1, FAN2, FAN3 and FAN4 --- are 12V at 0.3A NOTE and only support cooling fans below or up to that rating. Tyan takes no responsibility and will not be held liable for damage related to the misuse of these fan headers. - Page 12 2.5 Thermal Trip header (J5) This header is used to control the emergency overheat shutdown.

2.10 BIOS Flash Utility You can upgrade the BIOS of this motherboard by using the Flash Utility. See the System Resources page 45 for details. Also check that you have the newest BIOS, available from the Tyan website: http://www.tyan.com http://www.tyan.com... -
Page 17: Mounting The Motherboard
The diagrams above are only representative of a few solutions for installing a NOTE motherboard into the chassis. The installation procedure for installing your motherboard into the chassis may differ. http://www.tyan.com... -
Page 18: Installing Memory
Please keep in mind that although some memory modules may appear to be high-quality, they may contain inferior or substandard parts. The type of memory you choose to install should be checked against the memory compatibility list, which is available from Tyan’s website at http://www.tyan.com. -
Page 19: Installing The Cpu And Cooling Fan
2.13 Installing the CPU and Cooling Fan Intel Pentium 4 processors up to 2.0GHz can be used on this board. For more information on CPU compatibility, check Tyan’s website at http://www.tyan.com/ When installing your CPU, remember the following:... - Page 20 CPU socket. The Trinity i845 ships with a special Heatsink retention bracket with four prongs that plug directly into the four holes around the CPU socket. Once the bracket fully inserted, press down the white into the bracket to fully secure the bracket onto the board.
- Page 21 Alternatively, if you wish to also install chassis fans for increased cooling, headers are provided to power those fans as well. Chassis fan installation will vary depending on your chassis manufacturer’s design. Please check with your chassis manufacturer for details on proper chassis fan installation. http://www.tyan.com...

Page 22: Connecting Ide And Floppy Drives
Only Tyan-approved cables are recommended for this motherboard. If you are using an existing configuration with older cables, your system might not function NOTE properly. Use only Tyan-approved cables (i.e. the ones included with your new motherboard). Some sym ptoms of incorrectly installed HDDs are... - Page 23 Check power cables and cabling. May be a bad FDD does not power on power supply or IDE drive problem. Usually signifies that the cable is on backwards. FDD light is constantly on Reverse the cable at the floppy drive end and try again. http://www.tyan.com...

Page 24: Installing Add-In Cards
See the before (Figure 2.1a) and after (Figure 2.1b) example installation images below for details. Check orientation of card when installing Push card down with even force *Your PCIAGP slot may not look like those in the above diagrams; they are used NOTE simply as examples. http://www.tyan.com... -
Page 25: Connecting Ps/2, Usb, Serial Devices
The connectors can only be connected one way: be sure and check the orientation of the connector before installing it into the port. On some Trinity i845 models, the ATX I/O stack may not look like the diagram NOTE above, it is only used for example purposes. -
Page 26: Connecting The Power Supply
When you connect the cable into the motherboard’s 20-pin onboard connector, it will make a CLICK noise as it is installed. This is normal. Your ATX power connector may not look like those in the above diagram; they NOTE are used simply as examples. http://www.tyan.com... - Page 27 Installing a new motherboard may seem difficult, but by following these directions, you should have a fairly uneventful time installing our products. If you do encounter problems, your vendor/dealer will be able to help you, or you can consult one of our many technical support. http://www.tyan.com...

RAID controller. For best performance, we recommend that you use drives of identical model and capacity. By matching drives, you ensure compatibility as well. If you are planning to use an UDMA-66 or 100 drive, you must use an UltraDMA-66/100 cable (Tyan has included that cable with the motherboard). -

BIOS is having difficulty initializing the video display. Any other beep sequences that may or may not occur are probably due to memory problems. If calling Tyan Tech Support, be sure that you know how many beeps your board made, and how long the beeps were. Also have other information such as your attached add-in cards, drives and OS to help speed up the support process and come to a possible solution faster. -
Page 35: Appendix I: Glossary
Cache size: refers to the physical size of the cache onboard. This should not be confused with the cacheable area, which is the total amount of memory which can be scanned by the system in search of data to put into the cache. A typical setup would be a cache size of 512KB, and a http://www.tyan.com... - Page 36 EEPROM (Electrically Erasable Programmable ROM): also called Flash BIOS, is a ROM chip which can, unlike normal ROM, be updated. This allows you to keep up with changes in the BIOS programs without having to buy a new chip. Tyan’s BIOS updates can be found at http://www.tyan.com ESCD (Extended System Configuration Data): a format for storing information about Plug-n- Play devices in the system BIOS.
- Page 37 Form factor: an industry term for the size, shape, power supply type, and external connector type of the Personal Computer Board (PCB) or motherboard. The standard form factors are the AT and ATX, although Tyan also makes some Baby-AT and ATX Footprint boards. Global timer: onboard hardware timer, such as the Real-Time Clock (RTC).
- Page 38 SDRAM (Synchronous Dynamic RAM): called as such because it can keep two sets of memory addresses open simultaneously. By transferring data alternately from one set of addresses and then the other, SDRAM cuts down on the delays associated with non-synchronous RAM, which must close one address bank before opening the next. http://www.tyan.com...
- Page 39 ZIF Socket (Zero Insertion Force socket): these sockets make it possible to insert CPUs without damaging the sensitive CPU pins. The CPU is lightly placed in an open ZIF socket, and a lever is pulled down. This shift the processor over and down, guiding into the board and locking it into place. http://www.tyan.com...
