Icons
In order to help you navigate this manual and set up your system, we have
added several icons to our format.
This icon alerts you to particularly important details regarding the
setup or maintenance of your system. This icon often appears next
to information that may keep you from damaging your board or
system. While we will often point out the most vital paragraphs in a
chapter, you should always read every word in the text. Failing to do so can
lead to exasperation and expense.
Wherever possible, we have included step-by-step instructions for
setting up your system, which are indicated by this icon. However, it
is in your best interest to read an entire section (and perhaps the
entire manual) before you begin to fiddle with your motherboard.
While we have alerted you to potential dangers in several places in
the manual with this icon, these warnings should not be regarded as
the whole of your safety regimen. Never forget that computers are
electrical devices, and are capable of delivering a shock. Prevent damage to
yourself and to your board: always ensure that your system is turned off and
unplugged whenever you are working with it, and that you are equipped with a
static safety device.

T echnical Support
If a problem arises with your system, you should turn to your dealer for help
first. Your system has most likely been configured by them, and they should
have the best idea of what hardware and software your system contains.
Hence, they should be of the most assistance. Further, if you purchased your
system from a dealer near to you, you can actually bring your system in to
them to have it serviced, instead of attempting to do so yourself (which can
have expensive consequences).

information which will make configuration and setup much easier.
The next step is to properly ground yourself. First, unplug the power from your
computer case and then touch the metal casing of the power supply or any
metal part on the computer case. This will discharge any electricity from your
body. Take the motherboard out of the cardboard box and static bag, holding it
by its edges, and place it on a grounded anti-static surface, component side
up. Inspect the board for damage.
DO NOT APPL Y POWER TO THE BOARD IF IT HAS BEEN DAMAGED!
Press down on any of the socket ICs if it appears that they are not properly
seated (the board should still be on an anti-static mat). Do not touch the
bottom of the board. Remember, don’ t take any electronic device out of its
protective bag until you are ready to actually install it into the computer case.
If you don’t ground yourself, you risk zapping the motherboard or adapter
card. Subsequent problems may not arise immediately because electrostatic
discharge damage, unlike physical damage, causes the device to fail over time.
Install the motherboard into your case.
Follow the instructions provided by the case manufacturer for proper installation guidelines. TYAN recommends that you use only one screw to hold down
the motherboard. The rest of the mounting holes should be used for the plastic
standoffs. If your case does not have a hole for a standoff, simply cut off the
bottom of the plastic standoff so that the flat portion rests on the metal. The
adapter cards and the screws holding them down will keep your board flat. The
fastening screw should not short any of the traces on the motherboard. Make
certain that you do not overtighten the screw , as it will damage the
motherboard and possibly break internal traces in the surrounding area. The
hole you should use is located at the top-center of the board where the adapter
cards are fastened to the case.
Plug in the power connector as shown.
The following photos show the ATX power connector before (Figure 1) and
after (Figure 2) it has been plugged in.
The plastic clip on the power connector should lock over the plastic tab on the
onboard connector. You shouldn’t be able to plug the power connector in any
other way but just to be safe, make sure it looks like Figure 2 above. 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: T yan recommends using an A TX power
supply that conforms to industry standard revision 2.01.
Next, connect your IDE cables (if you’re using IDE hard drives).
The colored stripe on the cable indicating pin 1 should face towards the rear of
the case (towards the ATX connectors).
In Figure 3 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. In most cases,
this is the proper way of connecting your IDE cable to the hard drive. Figure 4
shows the IDE cable properly connected to the motherboard.
Contact your hard disk drive manufacturer or documentation for more information.
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 on
bootup: usually means
the cable is on
backwards.
• Hard drive lights are
constantly on: bad
IDE cable or defective
drives/motherboard.
Try another HDD.
• Hard drives do not
power up: check
power cables and
cabling. May also be a
bad power supply or
IDE drive.
Figure 3

Chapter 2
Board Installation
Now that you have installed your IDE drives, your floppies are next.
Pin 1 on the floppy cable is usually denoted by a red or colored stripe down
one side of the cable (see Figure 5). 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. Drive B:
is usually connected to the middle of the cable. Refer to your installation
instructions or call your dealer if you are unsure about attaching floppy drives.
Refer to Figure 5 below for a detailed anatomy of the floppy cable. Remember,
you can only have two floppy drives connected at any given time.
Figure 5
The colored stripe on the cable indicating pin 1 should face towards the rear of
the case (towards the ATX connectors), as with the IDE cables. Please refer to
your documentation for proper installation, or see Figure 4 on page 13.
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 . T ry another cable or floppy drive to verify.

• Light on the floppy is on constantly: a dead give-away that the cable is on
backwards. Reverse the cable at the motherboard end and try again.
Next are the Com and Printer ports.
W arning: 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 6 at the top of the next page shows the ATX double row connectors on
this board. The Com and Printer ports, as well as the other ports, are labeled.
Figure 6
Note: Only TYAN cables will work on this motherboard. If you are using an
existing case with old cables, your system may not function properly . Use
only TYAN-approved cables.
Connecting the USB and PS/2 ports.
This board includes ports for USB, PS/2 mouse, and PS/2 keyboard devices.
The location of these ports is shown in Figure 6 above. Note that, for this
http://www.tyan.com

board, the PS/2 mouse port is the upper PS/2 port, and the PS/2 keyboard port
is the lower PS/2 port.
The PS/2 connectors are probably quite familiar to you. The USB connectors,
however, may be foreign. The USB (Universal Serial Bus) 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. Close-ups of the USB
connector, as well as of the USB and PS/2 ports, are on the following page.
Figure 7 shows the USB ports and Figure 8 the PS/2 ports.
Installing your add-in cards is relatively simple but...
there are a few rules you need to follow when plugging in a card. In order to
assure proper operation and a quick installation, adhere to these guidelines:
• If you are going to install a PCI-Bus interface card on your system, be
aware that any one of the two PCI slots can support a Master or Slave
Figure 7 Figure 8

important!
device.
• NEVER force a card into a slot. If it doesn’t fit, look at the socket on the
computer to make sure there are no wires or other obstructions to the slot.
• NEVER plug an ISA card into a PCI slot or a PCI card in an ISA slot. Y ou
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. 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 each other
or are shorting.
If you follow these basic guidelines, there shouldn’t be any problems with
installation. However, if you do encounter any problems, have a qualified
professional install your cards for you or contact your card manufacturer .
Remember, always read the manuals and installation notes that come with the
adapter cards. They contain important information which will help you install
the components right, the first time.
Next, you need to install your 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. Because of this, your memory may not
work correctly in a TYAN board though it may work well in a competitor’s
board. This is because many of our competitors do not adhere to the strict
tolerances required for high performance. If you buy a TYAN board, you are
getting the best system available. To make installation easy and trouble free,
get high quality parts. Some brands we recommend are Advantage Memory ,
Corsair Microsystems, Millenium, Kingston Memory , QesT ec Incorporated,
Unigen, Micron Technology, and Crucial Technology. These DIMMs have
proven to be very stable on our boards and perform extremely well.

Figure 9
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 9
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. Do not shove
one end in first; doing so will bend the DIMM pins.
To lock the DIMM into place, push the plastic clips on either end of the slot
onto the notches in the ends of the DIMM (see Figure 10 on the next page). To
remove your DIMM, simply pull the clips back, and pull up on the module.
Place the DIMMs in an anti-static bag as soon as you remove them to avoid
static damage.

Finally , install your CPU.
Pentium II processors (233 through 450MHz) can be used on the T sunami. Please
refer to pages 29-30 for the correct CPU jumper settings for your board. 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. Y ou should be able to insert the CPU with minimal, but firm,
pressure. Do not press down hard on the CPU.
Currently , Intel produces two types of Pentium II processors: the active (or
boxed) processor and the passive processor (see Figures 11 and 12 on the next
page). These two types of processors are essentially the same in design; the
only difference lies in their cooling methods. The active processor is equipped
with a cooling fan and heat sink, while the passive processor is equipped with
a heat sink alone. Both types of CPUs provide the user with the same performance, and both types can be installed in the Pentium II slot on the Tsunami
board.

Installing CPU Retention Modules
Installation of a Pentium II processor requires a CPU retention module, which
is first secured onto the motherboard.
To attach the retention module,
place the motherboard on a flat
surface. Locate the key pin on
one end of the Pentium II slot on
the board. Then carefully line up
the key notch on the retention
module with the key pin on the
Pentium II slot (the key pin on
the Pentium II slot indicates the
correct orientation of the CPU).
Drop the retention module
(Figure 14 on the following page)
down over the Pentium II slot so
that the retention module sits flat
against the motherboard.
Tighten the screws in a clockwise manner to secure the module to the board.
Warning: Do not overtighten the screws as you may
damage the module and/or the motherboard.
Installing the Active Processor
When the retention module is securely installed, you
are ready to plug in the CPU. Press down firmly on the
CPU until you hear a “click” (see Figure 15). This clicking sound indicates that the CPU is fully locked into
Figure 14
S1846 Tsunami ATX
21
INSTALL
the retention module. If you have an active processor,
you will also need to connect the CPU’s cooling fan cable
to the cooling fan power connector on the board.
Locate the cooling fan connector (e.g. 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 A TX power connector that will force you to connect the fan cable correctly
(see Figure 16 below).
Figure 16
Installing the Passive Processor
The installation of the passive processor differs only slightly from that of the
active processor. Your passive CPU package should contain one CPU retention
module, one heat sink retention bracket with mounting locks, two mounting
attachments, and one heat sink lock.Install the retention module as explained in
the active processor section.
The heat sink mount (Figure 17) has two pins on the bottom and four pins on
the top. Notice that the bottom two pins are of different sizes. The size of the
Figure 15

Board Installation
pins and the holes in the motherboard will determine the correct orientation.
When the bracket is correctly installed, the four pins on top will be right next
to the Pentium II CPU slot.
Insert the heat sink mount into the
holes on the motherboard. When
the bracket is properly inserted into
the holes on the motherboard, you
will hear a clicking noise.
Align the CPU with the CPU
retention module. Make sure the heat sink is lined up with the heat sink mount
bracket. If you put the CPU in the wrong way , you may damage the CPU, the
motherboard, and/or the CPU socket. Slowly press down on the CPU module
until the CPU locks into place. Y ou will hear a clicking noise when the CPU is
locked securely into the module.
The heat sink lock (Figure 18) has four
notches which will correspond to the
four pins on the heat sink mounting
bracket. Gently slide the lock between
the heat sink and 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.
To remove the lock from the heat sink mounting bracket, gently press the ends
of the locks inward and pull.
Lock the heat sink mount to the board by inserting
the two mounting locks (Figure 19) into the pins of
the heat sink mounting bracket which are now below
the mainboard. There will be a click when the locks
are securely fastened.
Removing the CPU.
T o remove the CPU, move the locks to the center of
the CPU. A click will be heard when the CPU has
been unlocked. Gently pull up on the CPU, taking
care not to bend the motherboard or the CPU retention module.
To remove the lock from the retention module, gently press the ends of the
locks inward and pull.

Setting Jumpers
In this manual, the terms “closed” and “on” are used when referring to jumpers
(or jumper pins) that are active; “open” and “off” are used when referring to
jumpers (or jumper pins) that are inactive. Jumpers and pins are connected by
slipping the blue plastic jumper connector overtop of two adjacent jumper
pins. The metal rod inside the plastic shell bridges the gap between the two
pins, completing the circuit. See the drawings below for examples of “on” and
“off” pins and jumpers.
