Technical 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 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).

Unpacking
The motherboard package should contain the following:
(1) S2054 mainboard
(1) 40-pin IDE and 34-pin floppy cable pack
(1) 80-pin ATA-66 IDE cable
(1) S2054 Users Manual
(1) Driver disk
Installation
You are now ready to install your motherboard. The mounting hole pattern of
the S2054 matches the micro-ATX system board specifications. Your chassis
should support a standard micro-ATX mainboard form factor.
How to install our products right...the first time.
Whats the first thing I should do?
The first thing you should do is read this users manual. It contains important
information which will make configuration and setup much easier.
Here are some precautions you should follow when installing your motherboard:
http://www.tyan.com
10
(1) Ground yourself properly before removing your motherboard
from the antistatic bag. Unplug the power from your computer
and then touch any metal part on the computer case. (Or wear a
grounded wrist strap.)
(2) Hold the motherboard by its edges and do not touch the bottom of
the board.
(3) Avoid touching motherboard components, IC chips, connectors,
and leads.
(4) Avoid touching pins of memory modules and chips.
(5) Place motherboard on a grounded antistatic surface or on the
antistatic bag.
Having reviewed the precautions above, the next step is to take the motherboard out of the cardboard box and static bag, hold it by its edges, and place it
on a grounded antistatic surface, component side up. Inspect the board for
damage.
DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED!
!
important!
Press down on any of the socket ICs if it appears that they are not properly
seated (the board should still be on an antistatic mat). Do not touch the bottom
of the board. Remember, dont take any electronic device out of its protective
bag until you are ready to actually install it into the computer case. If you do
not 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.

Quick References for 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. See the Figure 2-1 for examples of
on and off pins and jumpers. The square pin in the diagram is Pin 1.
Jumpers and pins are connected by slipping the blue plastic jumper connector
overtop of two adjacent jumper pins (indicated by 1-2 or 2-3). The metal rod
inside the plastic shell bridges the gap between the two pins, completing the
circuit. See Figure 2-2 for more example of pin connections.

Locked Unlocked
JP3 OFF ON
By default, this jumper is set to the OFF (locked)
position. Having the Boot Block protection locked
will allow system-bootup even if the BIOS bootup
fails. In other words, the boot block acts as a backup
in case your BIOS fails to boot the system. If the
jumper is set to the ON position, this would allow the
Boot Block to refresh its BIOS code at the same time
you flash a new BIOS. Note: If the Boot Block is

unlocked (jumper ON) and if failure occurs during
a new BIOS Flash, you run the risk of rendering your entire system unbootable. The backup protection of the Boot Block will be lost.
Onboard LED
The onboard LED stays on when the power supply is plugged in even if the
motherboard is turned off. This is due to the suspend to RAM setting in the
BIOS (If supported)
INSTALL

Soft Power Connector
The Soft Power Connector is part of jumper block J9 (pins 6-8). The Tomcat
i810 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. If the Power
Button Function option is set to Suspend, pressing the power button once will
wake the system or send it to Suspend mode. In this case, you cannot turn the
system off unless you shut down through the Windows operating system or
you hold the power button down for four seconds.
Hardware Reset Switch Connector Installation
The Reset switch on your cases display panel provides you with the Hard-

ware Reset function, which is the same as power on/off. The system will do a
cold start after the Reset button is pushed.
CMOS RTC
The Real Time Clock (RTC) circuit, which provides the date and time for the
system is integrated into the 810 chipset. If the external battery for the RTC is
low, it will prevent your system from POSTing, and you will not get a display.
Normally the life span of an external battery is 2 years. If yours is running low,
you will need to replace it with a new 3V lithium battery (Sony CR2032).
Flash EEPROM
The Tomcat i810 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 59).
2. Mounting the Motherboard in the Chassis
Follow the instructions provided by the case manufacturer for proper installation guidelines. TYAN recommends that you make use of all mounting holes to
screw down the motherboard. 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.
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. Because of this, your memory may not
work correctly in a TYAN board though it may work well in a competitors
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
http://www.tyan.com

getting the best system available. To make installation easy and trouble free,
get extended memory vendors, please visit Tyans website at www.tyan.com go to the Memory Support area in the Support Section. The website memory
compatibility lists include DIMMs that have proven to be very stable on our
boards and perform extremely well.
Figure 2-3
*Note: The image above is used to illustrate a concept and may not represent the actual
image of your motherboard.
INSTALL
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
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 2-4 on the next page). In
some cases, pushing the memory module into the DIMM slot will move the
plastic clips inward, automatically locking the module into place. 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.

The Tomcat i810 uses a 64-bit data path from memory to CPU and can accommodate up to 512MB 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 2-5 below). All installed memory will be automatically detected,
so there is no need to set any jumpers.

4. Installing the CPU and Cooling Fan
Socket 370 type Celeron processors can be used on the Tomcat i810. 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. You should be able to insert the CPU into the socket with
minimal, but firm pressure. Do not press down hard on the CPU.
