Introduction
Overview
The S1857 Trinity 371 is a quality, high performance motherboard designed for
Socket 370 Intel Celeron and Slot 1 Intel PII/ PIII microprocessors. The Trinity
371 utilizes the Intel 440BX AGPset with AMI BIOS (S1857-B & S1857A-B) or
a VIA VT82C693A with Award BIOS for S1857 & S1857-A models. S1857 can
support Celeron/ PII/ PIII CPU speeds of 300MHz through 600MHz, and host
bus speeds of 66MHz to 133MHz.
( The VIA chipset versions bus speed is Auto-Determined by the CPU. The
BX version can support 133Mhz by overclocking the chipset but it is not
recommended by Intel
TM
and Tyan.)
The S1857 motherboard, with built-in AGP slot, provides high performance
capabilities that are ideal for a wide range of demanding applications such as
CAD, CAM, CAE, desktop publishing, 3D animation, and video production.
This system board in an ATX form factor offers far more features and
expandability than Micro ATX models. Some of the features included are
onboard dual channel PCI PIO, Bus Master IDE and UltraDMA/66, onboard
floppy controller, and onboard high speed I/O.
Flexibility and expandability have been designed into the Trinity 371. With I/O
and drive controller support built onboard, the one AGP slot, six PCI and one

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

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. 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.

1. Setting Jumpers
1-A. CPU Speed Settings (Jumpers JP10, JP11, JP12, JP13)
There are two steps to set the CPU speed. First, set the clock multiplier with
jumpers JP10 -13 according to the specification of your CPU using the chart
below. After the system is ready to boot up you will need to set the bus speed
in the BIOS setup. This is covered in detail in Chapter 3 of this manual.
!
Presently all Celeron CPUs use a 66MHz bus speed. (Tyan does not recommend operating CPUs, memory, or PCI Bus at higher than rated speed. Tyan

important!
If you have been locked out of your system because you forgot your password or set the CMOS incorrectly, follow the instructions below.
1. Power off the system
2. Set jumper JP2 to pins 2 and 3
3. Wait for 2 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-H Fan Speed Detect
When using Intels LANDesk system management software, you may monitor
the status of the CPU Fans by connecting them to the Fan1 connector. You
will NOT be able to monitor your CPU fan with the other Fan connectors.
1-I Soft Power Connector
The Soft Power Connector is part of
jumper block J16. The Trinity 371 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.

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-M Creative Labs Audio Connectors
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 MPEG connector
(J20) is for DVD and TV cards; the VIDEO connector is (J22); the CD connector
(J23) is for CD-ROMs.
1-N External SMI
The EXTSMI (External System Management Interface) connector, jumper JP16,
is used by some plug-in cards. Certain applications associated with these plugin cards use the interface for hardware control and queries.
1-O Intrusion Alarm Connector
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-P 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 440BX or Via Apollo Pro Plus 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 371 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 68).
2. Mounting the Motherboard in the Chassis
Follow the instructions provided by the case manufacturer for proper installa-
!
tion guidelines. TYAN recommends that you use only one screw to hold down
important!
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.
3. Installing Memory
Since TYAN boards are manufactured with performance in mind, you should

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.
Place the DIMMs in an anti-static bag as soon as you remove them to avoid
static damage.

Cache Memory
Celeron A processors have the L2 (Level 2) cache built into their architecture,
so there is no need for an L2 cache on the motherboard. The Celeron processor has a physical L2 cache size of 128KB and a cacheable memory area of
512MB.

4. Installing the CPU and Cooling Fan
Socket 370 type Celeron processors (300 through 533MHz) and Pentium II/III can
be used on the Trinity 371. Please refer to page 17 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.
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. 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.
Note: If two CPUs
are installed
simultaneously,
only the CPU in the
socket will be
detected. Furthermore, the socketed
CPU will have its
multiplier locked at
2.0. In order for you
to change the
multiplier, you
should only use one
CPU at a time.
INSTALL

important!
Figure 2-8
Push down lightly on the CPU, and lower the arm on the ZIF socket to secure
the CPU. A squeaking noise is normal as the arm lowers. After the CPU is
securely seated, install the appropriate cooling device. Tyan strongly
recomends a heatsink/fan combination. Consult with your case manufacturer
for other cooling options.

Chapter 2
Board Installation
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 371 board.

Currently S1857 does not support some older Slot 1, 66Mhz bus Pentium IIs
that use a 2.8 core voltage. Please refer to this link for the most updated
information on CPU support for the Trinity 371.

Installing CPU Retention
Modules
Installation of a Pentium II / III/
Celeron processor requires a CPU
retention module, which is first
secured onto the motherboard.
Note: Tyan provides a variety of
retention modules. For detailed
installation procedures of your
module, please refer to Appendix 2
located at the back of the manual.
Figure 2-11 Pentium II Slot Connector and Key Pin
http://www.tyan.com
26
To attach the retention module, place the motherboard on a flat surface. Locate
the key pin on one end of the CPU slot on the board. Then carefully line up the
key notch on the retention module with the key pin on the CPU slot(the key
pin on the CPU slot indicates the correct orientation of the CPU) See Figure 211 on the previous page.
Drop the retention module (Figure 2-12
right) down over the CPU slot so that
the retention module sits flat against the
motherboard. Secure the module with
the pins or screws provided.
Figure 2-12
Figure 2-13
Figure 2-14 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.

Line up the retention brace with the holes provided on the motherboard. At
the same time, make sure the CPU is lined up with the CPU slot. Lower the
CPU onto the motherboard. The mountings on the retention brace should fit
through the holes of the motherboard and the CPU should fit into the slot.
See Figure 2-15). Secure the retention brace. The end result should look like
Figure 2-16.

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 2-17 below.
Figure 2-17
INSTALL
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.
Note: The CPU fan activates after the VGA card is initalized and not when the
system boots up, therefore you may experience a 5 second delay before the
CPU fan is enabled.
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 2-18 on the
next page shows the IDE cable properly connected to the motherboard.
Contact your hard disk drive manufacturer or documentation for more information.

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 onbootup: usually means the cable is on back
wards.
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 2-20 below). 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.
INSTALL
Figure 2-20
S1857 Trinity 371

Chapter 2
Onboard Resource Settings
Refer to Figure 2-29 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:
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. Connecting the Power Supply
Tyan recommends using an ATX power supply that conforms to industry
standard revision 2.01. The Trinity 371 motherboard comes equipped with one
Figure 2-21
Figure 2-22

32
onboard power connector.
Figure 2-21 (previous page) 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 2-22
previous page). 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.
7. 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:
If you are going to install a PCI-Bus interface card on your system,
be aware that any one of the 6 PCI slots can support a Master
or Slave device.
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.
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.

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.
8. 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 2-23 and 2-24
above shows the USB ports on the left and PS/2 ports on the right (respectively).

Connecting Com and Printer Ports
Warning: When plugging in your keyboard and mouse, or when plugging
warning
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 2-25 at the top of the this page shows the ATX double row connectors
on this board. The Com and Printer ports, as well as the other ports, are
labeled.
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

These options allow you to specify the bus type used by each DMA channel.
The settings are PnP or ISA/EISA .
IRQn
These options specify the bus that the specified IRQ line is used on. These
options allow you to reserve IRQs for legacy ISA adapter cards. These options
determine if AMIBIOS should remove an IRQ from the pool of available IRQs
passed to devices that are configurable by the system BIOS. The available IRQ
pool is determined by reading the ESCD NVRAM. If more IRQs must be
removed from the pool, you can use these options to reserve the IRQ by
assigning an ISA/EISA setting to it. Onboard I/O is configured by AMIBIOS.
All IRQs used by onboard I/O are configured as PCI/PnP. IRQ12 only applies if
the Mouse Support option in Advanced Setup is set to Disabled. IRQ14 and 15
will not be available if the onboard PCI IDE is enabled. If all IRQs are set to
ISA/EISA and IRQ14 and 15 are allocated to the onboard PCI IDE, IRQ9 will
still be available for PCI and PnP devices, because at least one IRQ must be
available for PCI and PnP devices. The settings are ISA/EISA or PCI/PnP.
Reserved Memory Size
This option specifies the size of the memory area reserved for legacy ISA
adapter cards. The settings are Disabled, 16K, 32K, or 64K.

option is set to Disabled. The settings are C0000, C4000, C8000, CC000, D0000,
D4000, D8000, or DC000.
PCI Device Search Order
This option changes the BIOS scan order of the PCI slot - from first to last or
last to first. The settings are First-Last or Last-First.
BIOS Devnode for Shadow RAM
This option is used for some add-on card ROMs which do not claim the
correct memory range that they occupy. The settings are Disabled or Enabled.

Flash Writer Utility
The AMI Flash Writer Utility is now included in the AMIBIOS (S1857-B &
S1857A-B) and so it is simpler to upgrade the BIOS of your mainboard. The
system BIOS is stored on a flash EEPROM ROM chip on the mainboard which
can be erased and reprogrammed by following the directions below.
1. From the DOS prompt, rename the BIOS file that you have downloaded to
amiboot.rom and copy it on to a floppy disk.
2. Insert the floppy disk with the BIOS upgrade into the A: drive.
3. Turn the power off.
4. While holding the <Ctrl> and <Home> keys, turn the power on. The system
will begin to read from the A: drive, and write the BIOS information contained
on the floppy disk in that drive to the EEPROM ROM chip. When the BIOS
has been totally reprogrammed, the system will reboot with the new BIOS in
operation.
5. If the system does not reboot in three minutes, power down the system wait
a few seconds, and then turn the power back on again. You will be prompted to
press <F1> to run Setup. You may check your settings at this time, or simply
save and exit the program.
The AWARDBIOS Flash writer utility is now included in the AWARDBIOS.
Like the AmiBIOS, the AWARDBIOS can be upgraded by reprogramming the
flash EEPROM ROM chip on the mainboard. Follow the instructions below for
a quick and easy upgrade to your BIOS. (For more detailed instructions please
refer to the AWARDBIOS settings chapter. S1857 & S1857A only)
1. Download the AWDFLASH.exe from the Tyan website
2. Download the latest AWARDBIOS update for your motherboard.
3. Copy both the AWDFLASH.EXE & *.BIN files to a floppy disk.
4. Reboot system to DOS mode.
5. Insert floppy disk with the BIOS upgrade into the A: drive
6. Type AWDFLASH.EXE x.BIN x being the filename of the BIOS upgrade.
7. The program will ask you to backup your existing BIOS file, select yes.
8. You are then prompted to reboot, select yes
9. The program will ask you are you sure?, select yes.
10. If the system does not reboot in three minutes, power down the system
wait a few seconds, and then turn the power back on again. You will be
prompted to press <Delete> to run Setup. You may check your settings at
this time, or simply save and exit the program.

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 A ttachment 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.
ATX 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.
74
http://www.tyan.com
Bandwidth refers to carrying capacity. The greater the bandwidth, the more
data the bus, phone line, or other electrical path, can carry. Greater bandwidth,
then, also results in greater speed.
A BBS (Bulletin Board System) is a computer system with a number of
modems hooked up to it which acts as a center for users to post messages and
access information.
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.
GLOSSARY
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
S1857 Trinity 371
75
Appendix 1
Glossary
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.
CMOS Complementary 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).
DIMM Dual 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.
DMA Direct 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.
DRAM Dynamic 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.
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
http://www.tyan.com
76
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/html/drivers.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.
GLOSSARY
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).
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.
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.
GLOSSARY
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
S1857 Trinity 371
79
Appendix 1
Glossary
is transmitted in serial form, one bit after another).
SIMM Single 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.
SRAM Static 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/33 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.

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

Award BIOS Configuration
Introduction to Setup
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 CMOS RAM, 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.
The AwardBIOS 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.
Starting Setup
The AwardBIOS is immediately activated when you first turn on the computer.
The BIOS reads system configuration information in CMOS RAM and begins
http://www.tyan.com
86
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 or by simultaneously pressing <Ctrl>, <Alt>, and
<Esc> keys 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.
In Case of Problems
If, after making and saving system changes with Setup, you discover that your
computer no longer is able to boot, the EliteBIOS supports an override to the
CMOS settings that resets your system to its default configuration.

You can invoke this override by immediately pressing <Insert> when you
restart your computer. You can restart by either using the ON/OFF switch, the
RESET button or by pressing <Ctrl>, <Alt> and <Delete> at the same time.
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.

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.

Virus Warning
When enabled, you receive a warning message if a program (specifically, a
virus) attempts to write to the boot sector or the partition table of the hard disk
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.
http://www.tyan.com
96
Swap Floppy Drive
This field is effective only in systems with two floppy drives. Selecting
Enabled assigns physical drive B to logical drive A, and physical drive A to
logical drive B.
Boot Up Floppy Seek
When Enabled, the BIOS tests (seeks) floppy drives to determine whether they
have 40 or 80 tracks. Only 360-KB floppy drives have 40 tracks; drives with 720
KB, 1.2 MB, and 1.44 MB capacity all have 80 tracks. Because very few modern
PCs have 40-track floppy drives, we recommend that you set this field to
Disabled to save time.
Boot Up NumLock Status
Toggle between On or Off to control the state of the NumLock key when the
system boots. When toggled On, the numeric keypad generates numbers
instead of controlling cursor operations.
IDE HDD Block Mode
Enables multi-sector transfers from the IDE drive in PIO mode.
Gate A20 Option
Gate A20 refers to the way the system addresses memory above 1 MB
(extended memory). When set to Fast, the system chipset controls Gate A20.
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.

Award BIOS Configuration
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.
PCI/VGA Palette Snoop
Your BIOS Setup many not contain this field. If the field is present, leave at
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.
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.
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.

Bank 0/1, 2/3, 4/5 DRAM Timing
The system board designer must select the proper value for these fields,
according to the specifications of the installed DRAM chips. Turbo mode
reduces CAS access time by 1 clock tick.
SDRAM Cycle Length
This field sets the CAS latency timing.
DRAM Clock
Allows you to set the memory clock speed to either 66MHz or equal to the
CPU clock speed, depending on your memory speed.
Memory Hole
This option specifies the location of an area of memory that cannot be
addressed on the ISA bus. The settings are Disabled, 512KB-64KB, or 15MB16MB.
Read Around Write
Increases memory throughput.
