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). Please refer to your dealer for specific warranty
coverage details.
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

Here are some precautions you should follow when installing your motherboard:
(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.
Jumpers and pins are connected by slipping the 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.

1-G Soft Power Connector
The Soft Power Connector is part of jumper block J16. The Trinity 400 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.
1-H Hardware Reset Switch Connector Installation
The Reset switch on your cases display panel provides you with the Hardware Reset function, which is the same as power on/off. The system will do a
cold start after the Reset button is pushed. (J16 pin 7 & 8)
1-I Creative Labs Audio Connectors (optional)
There are four black 4-pin
connectors onboard which are
used for various peripherals
audio signals. The digital signal
that comes in through these
connectors is directed through
the Creative Labs ES1373 PCI
sound chip, and the digital signal
is turned into an audio signal
which goes out through the
speaker. The TDA connector
(J21) is for modem audio; the
VIDEO connector is (J22); the CD
connector (J23) is for CD-ROMs.

The J7 connector is an intrusion alarm, that can be connected to the system
chassis. When active (J7 is connected to the chassis), this alarm will alert the
system administrator anytime someone opens the systems case.

1-K Power LED Connector
Jumper D31 is a three pin power LED header that can be used if you have a 3
pin Power LED. Otherwise refer to panel connector J16 for 2 pin LEDs. 3 pin
LEDs can still be used on J16 where pin 13 would be for the Ground pin.
CMOS RTC
The Real Time Clock (RTC) circuit, which provides the date and time for the
system is integrated into the Via Apollo Pro Plus 133A AGPset. 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 Trinity 400 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 60).
2. Mounting the Motherboard in the Chassis
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 mother-
!
board and possibly break internal traces in the surrounding area. The hole you
important!
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. It is highly recommended that the memory
DIMMs are installed prior to connecting the power supply. 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 brandname 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 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, QesTec
Incorporated, Unigen, Micron Technology, and Crucial Technology. These
DIMMs have proven to be very stable on our boards and perform extremely
well.
warning
This motherboard operates on a 3.3 volt standby for the DIMM banks .
Because of this, you need to UNPLUG the AC power cord before installing
your DIMM memory modules. Otherwise, the motherboard may automatically
power up when the memory is inserted into the slot.
20
http://www.tyan.com
Figure 2-5*
*Note: 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 2-5
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 2-6 on the next page).
To remove your DIMM, simply pull the clips back, and pull up on the module.
INSTALL
Place the DIMMs in an anti-static bag as soon as you remove them to avoid
static damage.

The Trinity 400 uses a 64-bit data path from memory to CPU and can accommodate up to 768MB 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 2-7 below). All installed memory will be automatically detected,

4. Installing the CPU and Cooling Fan
Socket 370 type Celeron processors (300 through 533MHz) and Slot 1 type Pentium
II/III can be used on the Trinity 400. Please refer to page 15 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. You
should be able to insert the CPU into the socket with virtually zero force.
Do not press down hard on the CPU as you will bend or break pins.
Installing Socket 370 Type CPUs
Pin 1 on the CPU is denoted by a small dot on one of the corners and Pin 1 on
the ZIF socket is denoted by an angled corner.
Note: If two CPUs

simultaneously,
there is a tremendous risk of
shorting out both
CPUs and the
motherboard. DO
NOT install 2CPUs
at the same time!
Figure 2-8
Push down lightly on the CPU, and lower the arm on the ZIF socket to secure
the CPU. (Figure 2-8) A squeaking noise is normal as the arm lowers. Never
force a CPU into a socket. Forcing a CPU to seat will bend the pins on the CPU
and possibly damage the motherboard. Check with your vendor or manufacturer for proper voltage selection.After the CPU is securely seated, install the
appropriate cooling device. Tyan strongly recommends a heatsink/fan combination. Consult with your case manufacturer for other cooling options.
http://www.tyan.com
24
Installing Slot1 Type CPUs
Currently, two types of cooling mechanisms are produced for Pentium II processors: active (figure 2-9a) and passive (figure 2-9b). These two types of cooling
methods essentially perform the same function. The active cooler is equipped
with a cooling fan and heat sink, while the passive cooler is simply a larger heat
sink with no fan. The type of cooler used has no effect on performance, and both
types can be installed in the CPU slot on the Trinity 400 board.

procedures of your module, please refer to Appendix 2 located at the back of
the manual.
Figure 2-10 below shows a side view of a retention brace securing both sides of
the SECC2 CPU. When both sides are properly positioned, press both braces
against the sides of the CPU and carefully lift them over the CPU slot on the
motherboard. When lowering the brace and CPU, be sure to line up the key
notch on the brace with the key pin on the slot located on the motherboard.

If you have an active cooler, you will also need to connect the CPUs 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 CPUs 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 2-13 on the following page.

Removing CPU
When removing the CPU, pull lightly on the pegs sucuring the retention brace
and remove the CPU and retention brace at once. This may require careful firm
tugs to pull the CPU out of its slot.
5. Connecting IDE and Floppy Drives
The colored stripe on a ribbon cable should face toward the battery on the
motherboard. Make sure that 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. In most cases, this is the
proper way of connecting your IDE cable to the hard drive. Figure 2-14 on the
next page shows the IDE cable properly connected to the motherboard.
Contact your hard disk drive manufacturer or documentation for more information.

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.
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 2-15 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. 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 2-15 for a detailed anatomy of the floppy cable. Remember, you
can only have 2 floppy drives connected at any given time.
The color stripe on the cable should face toward the top of your chassis, or
toward the battery on the motherboard. Please refer to your documentation for
proper installation.
Some symptoms of incorrectly installed floppies are:
Figure 2-15
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. Try another cable or floppy drive to
verify.
Light on the floppy is on constantly: a dead giveaway that the cable
is on backwards. Reverse the cable at the motherboard end and try
again.
6. Installing Add-on Cards
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:
!
important!
S1854 Trinity 400
NEVER force a card into a slot. If it doesnt fit, look at the
socket on the computer to make sure there are no wires or
other obstructions to the slot.
29
Chapter 2
Board Installation
NEVER plug an ISA card into a PCI slot or a PCI card in an ISA
slot. You 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. Dont 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
warning
NOTE: This motherboard operates on a 3.3 volt standby for PCI
v2.2. Because of this, you need to UNPLUG the AC power cord
before installing your card. Otherwise, the motherboard may
automatically power up when the card is inserted into the slot.
If you follow these basic guidelines, there shouldnt 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.
7. Connecting PS/2, USB, Serial & Parallel Devices
This board includes ports for USB, PS/2 mouse, and PS/2 keyboard devices.
Note that, for this 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. Figures 2-16 and 2-17 on the following page shows the USB ports on
the left and PS/2 ports on the right (respectively).

8. Connecting the Power Supply
Tyan recommends using an ATX power supply that conforms to industry
standard revision 2.01. The Trinity 400 motherboard comes equipped with one
onboard power connector. Figure 2-16 below shows an ATX power connector. When plugging in the power connector, make sure that the plastic clip on
the power connector is aligned with the plastic tab on the onboard connector
(see Figure 2-17 below). Make 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.

You are done!
Other than checking the jumper settings and cable connections and putting
the case back on, you are done. Installing a new motherboard may sound
difficult, but by following these directions, you should have a fairly uneventful
time installing our products. If you do encounter problems, your dealer will be
able to help you, or you can consult one of our many technical support

BIOS Configuration
Introduction to Setup
The BIOS section of the manual is subjected to change without notice and is
!
important!
provided here for reference purposes only. The settings and configurations
of the BIOS are current at the time of print, although they may not be exactly
the same as that displayed on your screen.
This manual describes the Award BIOS Setup program. The Setup program lets
you modify basic system configuration settings. The settings are then stored
in a dedicated battery-backed memory, called NVRAM, that retains the
information when the power is turned off.
The Award BIOS in your computer is a customized version of an industrystandard BIOS for IBM PC ATcompatible personal computers. It supports
Intel x86 and compatible processors. The BIOS provides critical low-level
support for the system central processing, memory, and I/O subsystems.
INSTALL
The Award BIOS has been customized by adding important, but nonstandard,
features such as virus and password protection, power management, and
detailed fine-tuning of the chipset controlling the system. The rest of this
manual is intended to guide you through the process of configuring your
system using Setup.
S1854 Trinity 400
33
Chapter 3
BIOS Configuration
Starting Setup
The Award BIOS is immediately activated when you first turn on the computer.
The BIOS reads system configuration information in CMOS RAM and begins
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 <Del> immediately after switching the system on, or
2. By pressing the <Del> key when the following message appears briefly at
the bottom of the screen during POST:
TO ENTER SETUP BEFORE BOOT PRESS DEL KEY
If the message disappears before you respond and you still wish to enter
Setup, restart the system to try again by turning it OFF then ON or pressing
the RESET button on the system case. You may also restart by simultaneously
pressing <Ctrl>, <Alt>, and <Delete> keys. If you do not press the keys at the
correct time and the system does not boot, an error message appears and you
are again asked to
PRESS F1 TO CONTINUE, DEL TO ENTER SETUP
Setup Keys
The table on the following page shows how to navigate in Setup using the
keyboard.
Getting Help
Press F1 to pop up a small help window that describes the appropriate keys to
use and the possible selections for the highlighted item. To exit the Help
Window press <Esc> or the F1 key again.
If, after making and saving system changes with Setup, you discover that your
computer is no longer able to boot, restart by either using the ON/OFF
switch, the RESET button or by pressing <Ctrl>, <Alt> and <Delete> at the
same time, or clear the CMOS (see page 17 for details)
The best advice is to alter only settings that you thoroughly understand. In
particular, do not change settings in the Chipset screen without a good reason.
The Chipset defaults have been carefully chosen by Award Software or your
system manufacturer for the best performance and reliability. Even a seemingly
small change to the Chipset setup may causing the system to become unstable.

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. Your
system designer can decide that certain items should not be available for user
configuration and remove them from the Setup program.
Main Setup Menu
When you enter the AwardBIOS CMOS Setup Utility, a Main Menu, similar to
the one shown below, appears on the screen. The Main Menu allows you to
select from several Setup functions and two exit choices. Use the arrow keys to
select among the items and press enter to accept and enter the sub-menu.
A brief description of each highlighted selection appears at the bottom of the
screen. Following is a brief summary of each Setup category.

HARD DISKS
The BIOS supports up to four IDE drives. This section does not show
information about other IDE devices, such as a CD-ROM drive, or about other
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. Match the specifications of your installed IDE hard drive(s) with the
preprogrammed values for drive types 1 through 45.
2. Select User and enter values into each drive parameter field.
3. Use the IDE HDD Auto Dectection function in Setup.
Here is a brief explanation of drive specifications:
Type: The BIOS contains a table of pre-defined drive types. Each defined drive
type has a specified number of cylinders, number of heads, write
precompensation factor, landing zone, and number of sectors. Drives whose
specifications do not accommodate any pre-defined type are classified as type
user.
Size: Disk drive capacity (approximate). Note that this size is usually slightly
greater than the size of a formatted disk given by a disk-checking program.
Cyls: Number of cylinders
Head: Number of heads
Precomp: Write precompensation cylinder
Landz: Landing zone
Sector: Number of sectors
Mode: Auto, Normal, large, or LBA
Auto: The BIOS automatically determines the optimal mode.
Normal: Maximum number of cylinders, heads, and sectors
supported are 1024, 16, and 63.
Large: For drives that do not support LBA and have more than 1024
cylinders.
LBA (Logical Block Addressing): During drive accesses, the IDE
controller transforms the data address described by sector, head, and
cylinder number into a physical block address, significantly
improving data transfer rates. For drives with greater than 1024
cylinders.

During the power-on self-test (POST), the computer stops if the BIOS detects a
hardware error. You can tell the BIOS to ignore certain errors during POST and
continue the boot-up process. These are the selections:

Memory
You cannot change any values in the Memory fields; they are only for your
information. The fields show the total installed random access memory (RAM)
and amounts allocated to base memory, extended memory, and other (high)
memory. RAM is counted in kilobytes (KB: approximately one thousand bytes)
and megabytes (MB: approximately one million bytes).
RAM is the computers working memory, where the computer stores programs
and data currently being used, so they are accessible to the CPU. Modern
personal computers may contain up to 64 MB, 128 MB, or more.
Base Memory: Typically 640 KB. Also called conventional memory.
The DOS operating system and conventional applications use this
area.
Extended Memory: Above the 1-MB boundary. Early IBM personal
computers could not use memory above 1 MB, but current PCs and
their software can use extended memory.
Other Memory: Between 640 KB and 1 MB; often called high
memory. DOS may load terminate-and-stay-resident (TSR) programs,
such as device drivers, in this area, to free as much conventional
memory as possible for applications. Lines in your config.sys file that
start with loadhigh load programs into high memory.

drive. You should then run an anti-virus program. Keep in mind that this
feature protects only the boot sector, not the entire hard drive. Note: Many
disk diagnostic programs that access the boot sector table can trigger the
virus warning message. If you plan to run such a program, we recommend that
you first disable the virus warning.
CPU Internal Cache/External Cache
Cache memory is additional memory that is much faster than conventional
DRAM (system memory). CPUs from 486-type on up contain internal cache
memory, and most, but not all, modern PCs have additional (external) cache
memory. When the CPU requests data, the system transfers the requested data
from the main DRAM into cache memory, for even faster access by the CPU.
The External Cache field may not appear if your system does not have external
cache memory.
CPU L2 Cache ECC Checking
Enables Error Checking and correction (ECC) on the L2 cache onboard the
CPU.
Quick Power On Self Test
Select Enabled to reduce the amount of time required to run the power-on selftest (POST). A quick POST skips certain steps. We recommend that you
normally disable quick POST. Better to find a problem during POST than lose
data during your work.
Boot Sequence
The original IBM PCs loaded the operating system from drive A (floppy disk),
so IBM PC-compatible systems are designed to search for an operating system
first on drive A, and then on drive C (hard disk). However, modern computers
usually load the operating system from the hard drive, and may even load it
from a CD-ROM drive. The BIOS now offers a large number of boot devices
and boot sequence options.

Gate A20 Option
Gate A20 refers to the way the system addresses memory above 1 MB

When set to Normal, a pin in the keyboard controller controls Gate A20.
Setting Gate A20 to Fast improves system speed, particularly with OS/2 and
Windows.
Memory Parity/ECC Check
Select Enabled or Disabled. If Enabled, allows memory checking when the
BIOS detects the presence of ECC or Parity DRAM.
Typematic Rate Setting
When Disabled, the following two items (Typematic Rate and Typematic
Delay) are irrelevant. Keystrokes repeat at a rate determined by the keyboard
controller in your system. When Enabled, you can select a typematic rate and
typematic delay.
Typematic Rate (Chars/Sec)
When the typematic rate setting is enabled, you can select a typematic rate
(the rate at which character repeats when you hold down a key) of 6, 8, 10,12,
15, 20, 24 or 30 characters per second.
Typematic Delay (Msec)
When the typematic rate setting is enabled, you can select a typematic delay
(the delay before key strokes begin to repeat) of 250, 500, 750 or 1000 milliseconds.

Security Option
If you have set a password, select whether the password is required every time
the System boots, or only when you enter Setup.

Disabled.
OS Select for DRAM > 64MB
Select OS2 only if you are running OS/2 operating system with greater than 64
MB of RAM on your system.
Report No FDD for Win95
If the BIOS is set to report no FDD under Windows 95 there will be an error
message suggesting that a Floppy drive has not been installed. By leaving
this setting off disables the warning.
Video BIOS Shadow
Software that resides in a read-only memory (ROM) chip on a device is called
firmware. The EliteBIOS permits shadowing of firmware such as the system
BIOS, video BIOS, and similar operating instructions that come with some
expansion peripherals, such as, for example, a SCSI adaptor.
Shadowing copies firmware from ROM into system RAM, where the CPU can
read it through the 16-bit or 32-bit DRAM bus. Firmware not shadowed must
be read by the system through the 8-bit X-bus. Shadowing improves the
performance of the system BIOS and similar ROM firmware for expansion
peripherals, but it also reduces the amount of high memory (640 KB to 1 MB)
available for loading device drivers, etc.
Enable shadowing into each section of memory separately. Many system
designers hardwire shadowing of the system BIOS and eliminate a System
BIOS Shadow option.
BIOS
Video BIOS shadows into memory area C0000-C7FFF. The remaining areas
shown on the BIOS Features Setup screen may be occupied by other expansion card firmware. If an expansion peripheral in your system contains ROMbased firmware, you need to know the address range the ROM occupies to
shadow it into the correct area of RAM.

Power Management
This option allows you to select the type (or degree) of power saving for Doze,
Standby, and Suspend modes. See the section PM Timers for a brief description of each mode. This table describes each power management mode:
Determines the manner in which the monitor is blanked. The Blank Screen
option will let the system BIOS blank the screen when disabling video. V/H
sync+Blank will allow the system BIOS to turn off the V-SYNC and H-SYNC
signals running from the VGA card to the monitor.
If Modem Ring Resume is Enabled, it is possible to wake the system by dialing
in to it. This field determines which IRQ will be monitored for the incoming call.
BIOS
Soft-Off by PWRBTN
When you select Instant Off or Delay 4 Sec., turning the system off with the
on/off button places the system in a very low power usage state, either
immediately or after 4 seconds, with only enough circuitry receiving power to
detect wake-up event activity.
** PM Timers **
The following modes are Green PC power saving functions that are userconfigurable only in User Defined Power Management mode.
HDD Power Down
After the selected period of drive inactivity (1 to 15 minutes), the hard disk
drive powers down while all other devices remain active.
S1854 Trinity 400

Chapter 3
BIOS Configuration
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.
VGA
When On, any video activity is a PM event.
LPT & COM
Select none, or one or more, ports whose activity is a PM event.
HDD & FDD
When On, any hard drive or floppy drive activity is a PM event.
DMA/master
When On, any DMA or bus master activity is a PM event.
Modem Ring Resume
When Enabled, an input signal on the serial Ring Indicator (RI) line (in other
words, an incoming call on the modem) awakens the system from Suspend
mode.
RTC Alarm Resume
When Enabled, you can set the date and time at which the RTC (real-time
clock) alarm awakens the system from Suspend mode.
Wake Up on LAN
This feature allows remote power up through a LAN connection when used in
conjunction with a Wake on LAN compliant network adapter and appropriate
software.
Primary INTR

Flash Writer Utility
You can upgrade the BIOS on your motherboard by using the Flash Memory
Writer (FMW) utility. This utility can be downloaded from website. The system
BIOS is stored on a flash EEPROM chip on the mainboard, which can be
erased and reprogrammed by the FMW. The following three files make up the
FMW:
FLASHV73.EXE The Flash Memory Writer utility for Award to
Award upgrade.
README.TXTA text file of instructions.
1854v100.BIN*The new BIOS file.
(*This file name is subject to change and can have either a .bin or .rom extension.)
The FMW records (or programs) a new BIOS onto the flash memory chip. You
cannot upgrade an Award BIOS to an AMI BIOS or vice-versa.
http://www.tyan.com
60
Note: You should always clear your CMOS after flashing a BIOS. This will clear
out any stray settings from your old BIOS which may have been carried over
from the flashing process. Most problems encountered after flashing a BIOS
will be solved by this simple procedure (see Hardware CMOS & Password
Reset, page 16).
To reprogram the system BIOS, the CPU must be running in real mode. FMW
will not run if the CPU is operating in a protected or virtual mode. This means
that you cannot run it with Windows running or with any memory manager
software. You must disable any memory manager software before you can run
FMW. The easiest way to do this is as follows:
1) Boot your system from a bootable floppy disk with no CONFIG.SYS or
AUTOEXEC.BAT files, and then run FMW from a backup copy of your
support disk. You can make your back-up floppy bootable when you format it,
and use one disk for both purposes.
2) If you are using MS-DOS 6.x, you can use the feature that allows you to
bypass the CONFIG.SYS and AUTOEXEC.BAT files. You can access this
feature by pressing <F5> while the Starting MS-DOS... line is on the screen
during boot-up.
If you are uncertain whether or not you have a memory manager running, try
FMW. If it works, then there is no active memory manager on your system. If
you see a warning message about the CPU mode, follow the above directions
to get around the memory manager.
BIOS
Once you have your CPU in real mode, you can run FMW. You can copy the
contents of the Flash directory to your hard drive, or you can run the utility
from a backup of the support floppy disk. Either way, make sure that the new
BIOS file is in the same directory as the FMW utility.
To start FMW, change to the Flash directory if you are not already in it.
Type awdflash at the DOS command line and press the <Enter> key. The
FMW utility screen will appear:

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 computers 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. The 32-bit AGP channel
directly links the graphics controller to the main memory. While the channel
runs at only 66MHz, it supports data transmission during both the rising and
falling ends of the clock cycle, yielding an effective speed of 133MHz.
AT was the original form factor of IBMs PC.
ATAPI (AT Attachment Packet Interface), also known as IDE or ATA, is a drive
implementation that includes the disk controller on the device itself. It allows
CD-ROMs and tape drives to be configured as master or slave devices, just
like hard drives.
AT X form factor was designed to replace the AT form factor. It improves on the
AT design by rotating the board ninety degrees, so that the IDE connectors
are closer to the drive bays, and the CPU is closer to the power supply and
cooling fan. The keyboard, mouse, serial, USB, and parallel ports are built in.
GLOSSARY
Bandwidth refers to carrying capacity. The greater the bandwidth, the more
S1854 Trinity 400
67
Appendix
Glossary
data the bus, phone line, or other electrical path, can carry. Greater bandwidth,
then, also results in greater speed.
The BIOS (Basic Input/Output System) program resides in the ROM chip, and
provides the basic instructions for controlling your computers hardware. Both
the operating system and application software use BIOS routines to ensure
compatibility.
A buffer is a portion of RAM which is used to temporarily store data, usually
from an application, though it is also used when printing, and in most keyboard drivers. The CPU can manipulate data in a buffer before copying it, all at
once, to a disk drive. While this improves system performance--reading to or
writing from a disk drive a single time is much faster than doing so repeatedly-there is the possibility of losing your data should the system crash. Information stored in a buffer is temporarily stored, not permanently saved.
A bus is a data pathway. The term is used especially to refer to the connection
between the processor and system memory, and between the processor and
PCI or ISA local buses.
Bus mastering allows peripheral devices and IDEs to access the system
memory without going through the CPU (similar to DMA channels).
A cache is a temporary storage area for data that will be needed often by an
application. Using a cache lowers data access times, since the needed information is stored in the SRAM instead of in the slower DRAM. Note that the
cache is also much smaller than your regular memory: a typical cache size is
512KB, while you may have as much as 1GB of regular memory.
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 cacheable area of 512MB. In this
case, up to 512MB of the main memory onboard is capable of being cached.
However, only 512KB of this memory will be in the cache at any given moment.
Any main memory above 512MB could never be cached.
Closed and open jumpers Jumpers and jumper pins are active when they are
On or Closed, and inactive when they are Off or Open.
CMOSComplementary 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). Parallel ports transmit the bits of a byte on eight different wires at the
same time (that is, in parallel form, eight bits at the same time).
DIMMDual In-line Memory Modules are a faster and more capacious form of
RAM than SIMMs, and do not need to be installed in pairs.
DIMM bank DIMM banks are sometimes called DIMM sockets, because the
physical slot and the logical unit are the same. That is, one DIMM module fits
into one DIMM socket, which is capable of acting as a memory bank.
DMADirect Memory Access channels are similar to IRQs. DMA channels
allow hardware devices (like sound cards or keyboards) to access the main
memory without involving the CPU. This frees up CPU resources for other
tasks. As with IRQs, it is vital that you do not double up devices on a single
line. Plug and Play devices will take care of this for you.
In Doze mode, only the CPUs speed is slowed.
DRAMDynamic RAM is a widely available, very affordable form of RAM
which has the unfortunate tendency to lose data if it is not recharged regularly
(every few milliseconds). This refresh requirement makes DRAM three to ten
times slower than non-recharged RAM such as SRAM.
GLOSSARY
EDO RAM (Extended Data-Out RAM) speeds access to memory locations by
assuming that memory addresses are static: the next time it looks for a bit of
data, it will be at the same spot, or one nearby.
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.
TYANs BIOS updates can be found at:
http://www.tyan.com/support/html/bios_s1854.html
ESCD (Extended System Configuration Data) is a format for storing informa-
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.
Handshaking is a form of encryption. One system, typically the server, sends
an encryption scheme to another agent, typically a client. Thus, the clients
data is protected during transmittal to the server.
HDD stands for Hard Disk Drive.
H-SYNC controls the horizontal properties of the monitor.
IC (Integrated Circuit) is the formal name for the computer chip.
IDE Integrated Device (or Drive) Electronics is a simple, self-contained hard
drive interface. It can handle drives up to 8.4GB in size. Almost all IDEs sold
now are in fact Enhanced IDEs (EIDEs).
IDE INT (IDE Interrupt) is a hardware interrupt signal that goes to the IDE.
I/O Input/Output is the connection between your computer and another piece
of hardware (mouse, keyboard, etc.).
IRQ An Interrupt Request is an electronic request that runs from a hardware
device to the CPU. The interrupt controller assigns priorities to incoming
requests and delivers them to the CPU. It is important that there is only one
device hooked up to each IRQ line; doubling up devices on IRQ lines can lock
up your system. Happily, Plug and Play operating systems take care of these
details for you.
ISA stands for Industry Standard Architecture. ISA is a slower 8- or 16-bit BUS
(data pathway).
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).
http://www.tyan.com

NVRAM ROM and EEPROM are both examples of Non-Volatile RAM, memory
that holds its data without power. DRAM, in contrast, is volatile.
OEMs (Original Equipment Manufacturers) like Compaq or IBM package other
companies motherboards and hardware inside their case and sell them.
The parallel port transmits the bits of a byte on eight different wires at the
same time (that is, in parallel form, eight bits at the same time).
PCI stands for Peripheral Component Interconnect. PCI is a 32-bit local bus
(data pathway) which is faster than the ISA bus. Local buses are those which
operate within a single system (as opposed to a network bus, which connects
multiple systems).
The PCI PIO (PCI Programmable Input/Output) modes are the data transfer
modes used by IDE drives. These modes use the CPU for data transfer (DMA
channels do not). PCI refers to the type of bus used by these modes to
communicate with the CPU.
PCI-to-PCI bridge allows you to connect multiple PCI devices onto one PCI
slot.
Pipeline burst SRAM is a fast secondary cache. It is used as a secondary
cache because SRAM is slower than SDRAM, but usually larger. Data is
cached first to the faster primary cache, and then, when the primary cache is
full, to the slower secondary cache.
GLOSSARY
Pipelining improves system performance by allowing the CPU to begin
executing a second instruction before the first is completed. A pipeline can be
likened to an assembly line, with a given part of the pipeline repeatedly
executing a set part of an operation on a series of instructions.
PM timers (Power Management timers) are software timers that count down
the number of seconds or minutes until the system times out and enters sleep,
suspend, or doze mode.
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.
The term RAM (Random Access Memory), while technically referring to a type
of memory where any byte can be accessed without touching the adjacent
data, is often used to refer to the systems main memory. This memory is
available to any program running on the computer.
ROM (Read-Only Memory) is a storage chip which contains the BIOS (Basic
Input/Output System), the basic instructions required to boot the computer
and start up the operating system.
SDRAM (Synchronous Dynamic RAM) is so-called 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.
The serial port 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).
SIMMSingle In-line Memory Modules are the most common form of RAM.
They must be installed in pairs, and do not have the carrying capacity or the
speed of DIMMs.
SIMM bank/socket SIMM sockets are the physical slots into which you stick
SIMM modules. A pair of SIMM sockets form a SIMM bank, and act as a unit.
If only one socket is filled, the bank will not operate.
In Sleep/Suspend mode, all devices except the CPU shut down.
SRAMStatic RAM, unlike DRAM, does not need to be refreshed in order to
prevent data loss. Thus, it is faster, and more expensive.
In Standby mode, the video and fixed disk drive shut down; all other devices
operate normally.
UltraDMA/66 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.
VGA (Video Graphics Array) is the PC video display standard.
V-SYNC controls the vertical properties of the monitor.
ZIF socket Zero Insertion Force sockets make it possible to insert CPUs
without damaging the sensitive pins. The CPU is lightly placed in an open ZIF
socket, and the metal lever pulled down. This shifts the processor over and
down, guiding it into place on the board.

Installing SECC2 CPUs -Option 1
The following are alternative methods of installing the CPU and retention
module to that of chapter 2. On both sides of the SECC2 CPU reside the lower
tabs of the aluminum heat sink (see Figure A below). These tabs should snap
into the retention module. Currently, the retention module recommended for
securing the SECC2 CPU is included in the motherboard package. The retention brace consists of a foldable bracket that secures the CPU. (See Figure B
on the following page)

Line up the pegs of the retention brace with the holes provided on the
motherboard. Secure the retention brace by pressing firmly on the pins until
they lock into the motherboard.(Figure B)

Line up the CPU with the slot and slide CPU into the module from the top
until you here a click. (See Figure C). The end result should look like Figure D

Figure D above shows a properly installed SECC2 CPU using the retention
module. Note the direction of the CPU fan and the way in which the cable is
connected.
Remove CPU
Release the CPU from the retention module by gently bending the two ends of
the retention module away from the CPU. With the module out of the way, pull
the CPU out of the slot This may require careful firm tugs to pull the CPU out
of its slot.

Installing SECC2 CPUs - Option 2
Another method to secure an SECC2
CPU is by using the Universal
Retention Module (also provided by
Tyan). The universal retention
module is designed to accommodate
most versions of the Pentium
Celeron CPUs. Included in this
solution is an overhead clip to lock
the CPU into its slot along with the
side universal braces. See Figure E
(above) for the universal retention

module components. Install the
CPU, place the two side braces
at the ends of the CPU slot (see
Figure F left). The screws on
the motherboard should fit
through the holes of the
retention braces. Tighten and
secure both braces using a
screw driver. Next, carefully
insert the CPU between the
braces
and onto the CPU slot (see
Figure G below). Make sure the
Side Braces

CPU fan faces towards the
center of the motherboard.
When the CPU is secured
onto the slot, take the
overhead clip and insert
the ends of the clip over
the top of the side braces
(See Figure H on the
following page).
You will hear a click
when the overhead clip is
fitted securely into the
side braces.

Lowered lip
Make sure the lower lip of the
overhead clip is oriented towards the
opposite side of the CPU fan (see
Figure I left).
Removing CPU - Removal of the CPU is basically the
reverse order of the installation steps.
First remove the overhead clip. You need to push BOTH
side lock tabs (see Figure I above) towards the center of
the CPU in order to unlock it from the side braces. After
removing the overhead clip, you need to release the CPU
from the braces one side at a time. Press the center
release tab of one of the side braces (see Figure J
right) while gently pulling that side of the CPU out of its
slot. Repeat the procedure for the other side brace.
When both ends of the CPU is loose from the side
braces and the slot, you will be able to remove it from the
motherboard.
