Flexibility and high-integration have been designed into the Tomcat i810ef.

With I/O and drive controller support built onboard (along with the many

onboard features previously mentioned), the two PCI slots are free for more

add-on expansion cards. Remember to visit Tyans Website at www.tyan.com,

there you can find information on all of Tyans products along with FAQs,

distributors list, drivers, and BIOS setting explanations.

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.

Introduction

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).

Help resources:

1. See FAQ and beep codes sections of this manual.

2. See Tyan web site for FAQ, bulletins, driver updates, etc.

http://www.tyan.com

3. Contact your dealer or distributor for help BEFORE calling Tyan.

4. Check the Tyan user group: alt.comp.periphs.mainboard.tyan

Returning Merchandise for Service

During the warranty period, contact your distributor or system vendor FIRST

for any product problems. This warranty only covers normal customer use and

does not cover damages incurred during shipping or failure due to the

alteration, misuse, abuse, or improper maintenance of products.

For Resellers Only:

A receipt or copy of your invoice marked with the date of purchase is required

before any warranty service can be rendered. You can obtain service by calling

the manufacturer for a Return Merchandise Authorization (RMA) number. The

RMA number should be prominently displayed on the outside of the shipping

carton and the package should be mailed prepaid, or hand-carried to the

manufacturer. Tyan will pay to have the board shipped back to you.

INSTALL

Here are some precautions you should follow when installing your mother-

board:

(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 mother-

board 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!

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, 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 do

not ground yourself, you risk zapping the motherboard or adapter card.

Subsequent problems may not arise immediately because electrostatic dis-

charge 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.

Figure 2-1 Figure 2-2

The tables and maps on the following pages will help you set the jumpers for

CPU speed, Infrared, and external connector pin assignments, among others.

The miniature motherboard maps will help you locate the jumpers on your board.

A full-page map of the motherboard can be found on the next two pages.

1. Setting Jumpers

Note: There are no Jumper settings for CPU bus speed or clock multiplier on

the S2420 board. The Tomcat i810ef is designed to automatically detect the

socketed CPU and its proper speed settings.

1-A. J9 External Pin Assignments

1-B. Power LED (J14)

Jumper J14 is a 3-pin ACPI LED

header. If you need a 2-pin Power

LED header, use jumper J9 above.

1-C. Wake-On Ring Connector -optional (J28)

1-D. Wake-On LAN Connector -optional (J2)

1-E. Chassis Intrusion Alarm Connector (J1)

The J1 connector is an intrusion alarm, that can be

connected to the system chassis. When active (J1

is connected to the chassis), this alarm will alert the system administrator

anytime someone opens the systems case.

1-F. CPU Fan (J12) / Chassis Fan Connector (J11)

Flash EEPROM

The Tomcat i810ef 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. In order to flash the BIOS, do the following:

i. Shutdown the system, and close jumper JP3 to disable the boot

block protection (see Boot Block section below). Then boot

system to DOS.

ii. Type flash4mb followed by <ENTER> key.

iii. Choose whether to save or not save the old BIOS.

iv. Type in the BIOS filename, like BIOSFILE.ROM.

v. Flash utility will auto-complete the flash, including updating the

boot block at this point.

vi. Shutdown the system, and open jumper JP3 again.

Remember to clear the CMOS (see CMOS section below)

before turning your system back on.

See page 60 for more details about the Flash Writer Utility.

1-G. Boot Block Jumper (JP3)

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

un-bootable. The backup protection of the Boot

Block will be lost.

1-H. Clear CMOS and Reset Password (JP2)

If you have been locked out of your system

because you forgot your password or set the CMOS incorrectly, follow the

instructions on the next page.

1. Power off the system

2. Set jumper JP2 to pins 2 and 3

3. Wait for 10 seconds, then return jumper JP2 to pins 1 and 2.

4. Power on the system again.

By following this procedure, you will erase your password and reset the

CMOS to the BIOS defaults.

1-I. External Speaker Connector (J15)

The speaker should be connected to pins 1-4 of jumper J15.

1-J. CD Audio Connector (J32)

1-K. LCD Monitor Header (optional) (J36)

This is a 20-pin Silicon Image SII154 Digital video-

out header for LCD Monitors.

1-L. COM2 port header (J25)

This is a connector header for the COM2 Port

(see map for detailed location)

1-M. On Board Sound Enable/Disable (JP4)

This jumper setting is Enabled by default

1-N. Frontside USB Header (J38)

Certain computer chassis allow for a front-end USB port connection.

Therefore, this board provides a front side USB header should you decide to

set up a USB connector at the front side of your computer. Note: If you use

J38, you will be unable to use the TOP USB port at the back of the

motherboard. Both J38 and USB1 share the same channel.

1-Q. AUX Audio Connector (J44)

This connector is for plugging external audio

devices such as add on cards and other output

devices.

1-R. Server Management Connector (JP6)

The EXTSMI (External System Management Interface), connector JP6, is used

by some plug-in cards. Certain applications associated with these plug-in

cards use the interface for hardware control and queries.

Soft Power Connector

The Soft Power Connector is part of jumper block J9 (pins 6-8). The Tomcat

i810ef uses the chipset for power management, including turning on and off

the system. If the Power Button Function option in the BIOS Power Manage-

ment 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 cases 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 810e 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).

2. Mounting the Motherboard in the Chassis

Follow the instructions provided by the case manufacturer for proper installa-

tion 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 competitors board.

Chapter 2

Board Installation

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. For a list of recommended memory vendors, please visit Tyans

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.

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

(see previous page) 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.
