Introduction
Overview
The S1598 Trinity ATX is a quality, high performance mainboard designed for
Socket 7 microprocessors. This mainboard utilizes the VIA MVP3 100MHz
AGPset and host bus speeds of 66MHz to 100MHz. For CPU speed support,
please refer to the CPU Compatibility Chart in Tyan’s website
ATX also has 100MHz Front Side Bus support, which allows you to take full
advantage of 100MHz SDRAM memory modules.
The S1598 mainboard, 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 achieves high reliability with numerous features and yet is
small enough to be supported in an ATX form factor. 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 ATX. With I/O and drive
controller support built onboard, the one AGP slot, five PCI and two ISA slots
(one shared, seven usable) are free for numerous add-on expansion cards.

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 to you, you can actually bring your system in to
them to have it serviced, instead of attempting to do so yourself (which can
have expensive consequences).

Board Installation
Unpacking
The mainboard package should contain the following:
(1) S1598 mainboard
(1) 40-pin IDE and 34-pin floppy cable pack
(1) S1598 User’s Manual
(1) Driver CD
Precautions
What’s the first thing I should do?
The first thing you should do is read this user’s manual. It contains important
information which will make configuration and setup much easier.
Here are some precautions you should follow when installing your mother-
board:
(1) Ground yourself properly before removing your motherboard
from the antistatic bag. Unplug the power from your computer

and then touch any metal part on the computer case. (Or wear a
grounded wrist strap.)
(2) Hold the motherboard by its edges and do not touch the bottom of
the board.
!
important!
(3) Avoid touching motherboard components, IC chips, connectors,
and leads.
(4) Avoid touching pins of memory modules and chips.
(5) Place motherboard on a grounded antistatic surface or on the
antistatic bag.
Having reviewed the precautions above, the next step is to take the mother-
board out of the cardboard box and static bag, hold it by its edges, and place it
on a grounded antistatic surface, component side up. Inspect the board for
damage.
DO NOTAPPLYPOWER TOTHE BOARD IF IT HAS BEEN DAMAGED!
warning
Press down on any of the socket ICs if it appears that they are not properly
seated (the board should still be on an antistatic mat). Do not touch the
bottom of the board. Remember, don’t take any electronic device out of its
protective bag until you are ready to actually install it into the computer case.
If you do not ground yourself, you risk zapping the motherboard or adapter
card. Subsequent problems may not arise immediately because electrostatic
discharge damage, unlike physical damage, causes the device to fail over time.
*Power Supply Requirement: If you use anATX Power Supply, it should be
2.01 compliant. Standby current must be 750mAor higher (SB5V = 0.75A)
Installation Steps
You are now ready to install your mainboard. The mounting hole pattern of the
S1598 matches the ATX system board specifications. Your chassis should
have standard ATX mainboard form factor mounting holes and an ATX power
supply.

What is a Jumper?
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 examples of pin connections.
The tables and maps on the following pages will help you set the jumpers for CPU
speed, Infrared, and external connector pin assignments, among others. The
miniature motherboard maps will help you locate the jumpers on your board. A
full-page map of the motherboard can be found on the next two pages.

Board Installation
ACPI Bi-Color LED Connector (J5)
This connector provides a bi-color (green / yellow) LED for your computer
chassis. When the computer system is On, the Green LED will light up. If the
system is on stand-by mode, the Yellow LED will light up. Whenever there is
an incoming message, the LED will flash on and off.
Soft Power Connector
The Soft Power Connector is located on pins 6 and 8 of jumper block J3.
Pressing the Soft Power Button will turn the sytem on and off. Holding this
button for more than four seconds (when the system is on) will power down
the system. Pressing it again will reboot the system.
Speaker Connector Installation
The Trinity ATX provides a 4-pin header to connect the speaker. The speaker
is connected to jumper block J4.
CMOS RTC
The VIAMVP3AGPset includes a Real Time Clock (RTC) circuit, which
provides the date and time for the system. If the external battery for the RTC is
low, you will lose your BIOS settings. 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).
USB
There are two ATX Universal Serial Bus ports on the back of the board. The
board also has an additional USB header (USB2, USB3) on the edge of the
board near the third PCI slot. This header can be used to connect a USB port
on the front of the chassis.
FlashEEPROM
The Trinity ATX uses flash memory to store BIOS programs. It can be easily
updated if necessary using the flash utility (see page 57). Tyan does not
recommend flashing the BIOS unnecessarily. Check the Tyan web site for the
latest BIOS revision.
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
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
16
Download from Www.Somanuals.com. All Manuals Search And Download.
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
should use is located at the top-center of the board where the adapter cards
are fastened to the case.
3. Installing Memory
Since TYAN boards are manufactured with performance in mind, you should
use add-in components that match. Some DIMM modules may seem to be high
quality because of name or feel but that does not guarantee real-world
usability. Some cheaper or OEM memory may have brand-name components,
but they may contain inferior or substandard parts which do not meet the
critical tolerances our products require. Because of this, your memory may not
work correctly in a TYAN board though it may work well in a competitor’s
board. 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 Corsair Microsystems,
Kingston Memory, and QesTec Incorporated. These DIMMs have proven to
be very stable on our boards and perform extremely well. For a list of recom-

Board Installation
Figure 2-3
*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 2-3
above shows how to sit the DIMM into its slot. To insert the DIMM, push
down vertically on the module with even force, as shown in the photo. Do not
shove one end in first; doing so will bend the DIMM pins.
To lock the DIMM into place, push the plastic clips on either end of the slot
onto the notches in the ends of the DIMM (see Figure 2-4 on the next page).
To remove your DIMM, simply pull the clips back, and pull up on the module.
Place the DIMMs in an anti-static bag as soon as you remove them to avoid
static damage.
The Trinity 100AT uses a 64-bit data path from memory to CPU and can
accommodate up to 384MB 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 Figure 2-5 below). All installed memory will be automatically
detected, so there is no need to set any jumpers.

4. Installing the CPU and Cooling Fan
Socket 7 processors (see Specifications
on page 5) can be used on the Trinity
ATX. Please refer to page 14 for the cor-
rect 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.
•
Before the CPU is installed, the
mainboard must be placed on a flat
surface. You should be able to insert
the CPU with minimal, but firm,
pressure. Do not press down hard on the
CPU.
Figure 2-6
In Figure 2-6, you can see the CPU and the
ZIF socket. Notice that the arm of the ZIF
socket is up. When this arm is up, the CPU
is unlocked from the socket and allows
you to remove or install a CPU. As the ZIF
socket is keyed to the processor that you
are using, you will only be able to install
the CPU one way, thus eliminating the
chance for error. Pin 1 on the CPU is
Figure 2-7
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.
!
important!
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 (Figure 2-7). Tyan
strongly recomends a heatsink/fan combination. Consult with your case
manufacturer for other cooling options.

Figure 2-8
Locate the cooling fan connector (e.g. CPU Fan, Fan1) on the motherboard. Plug
the CPU’s cooling fan cable into the cooling fan connector on the board. There
will be a plastic clip assembly similar to that of theATX power connector that will
force you to connect the fan cable correctly (see Figure 2-8 above).

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
Figure 2-10
your IDE cable to the harddrive. Figure 2-10 shows the IDE cable properly
connected to the motherboard. Contact your hard disk drive manufacturer or
documentation for more information.
ATA-66 IDE hard drives require a special IDE cable which has additional
grounding wires. The cable is sold separately, and is required when using
ATA-66 drives. This cable will also support all legacy IDE drives.
Some symptoms of incorrectly installed HDDs are:
•
Hard disk drives are not auto-detected: may be a Master / Slave problem
or a bad IDE cable. Contact your vendor.
•
Hard Disk Drive Fail message at bootup:may be a bad cable or lack of
power going to the drive.
•
•
No video or beeps on bootup: usually means the cable is on backwards.
Hard drive lights are constantly on: bad IDE cable or defective drives/
motherboard. Try another HDD.
•
Hard drives do not power up: check power cables and cabling. May
also be caused by a bad power supply or IDE drive.

Figure 2-11
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 2-11 on the following page). Most of the
current floppy drives on the market require that the colored stripe be posi-
tioned 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 2-11 for a detailed anatomy of the floppy cable. Remember, you
can only have 2 floppy drives connected at any given time.
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
The Trinity ATX requires an ATX power supply. The photos on the next page
show theATX power connector before (Figure 2-12) and after (Figure 2-13) it
has been plugged in. The plastic clip on the power connector should lock over
the plastic tab on the onboard connector. You shouldn’t be able to plug the
power connector in any other way but just to be safe, make sure it looks like

Make absolutely certain that you do not miss any pins, because if you do you
will void your warranty and cause damage to yourself or your motherboard
when you turn the system on. After connecting the power, make sure the
connector is seated firmly into its socket so it will not become loose or fall off
when the computer is jostled or moved. Note: Tyan recommends using one
that conforms to industry standard revision 2.01.
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 two PCI slots can support a Master
or Slave device.
NEVER force a card into a slot. If it doesn’t fit, look at the socket
on the computer to make sure there are no wires or other
obstructions to the slot.
!
important!
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
24
Download from Www.Somanuals.com. All Manuals Search And Download.
you do this.
•
When plugging the card in, especially when installing long cards,
try to push the entire card in at one time. Don’t force one end of
the card into the socket first and then the other. This will create a
rocking motion between the card and the slot and it will damage the
pins within the socket.
•
•
Make sure that the cards are seated securely into the slots.
Before turning on the system, make sure no cards are touching.
If you follow these basic guidelines, there shouldn’t be any problems with
installation. However, if you do encounter any problems, have a qualified
professional install your cards for you or contact your card manufacturer.
Remember, always read the manuals and installation notes that come with the
adapter cards. They contain important information which will help you install
the components right, the first time.
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.
Connecting Com and Printer Ports
warning
Warning: When plugging in your keyboard and mouse, or when plugging
anything into a serial or Com port, make sure that the power is off. Connecting
these devices and ports while the power is on is called “hot plugging,” and
may damage your system.
Figure 2-14 on the previous page shows the ATX double row connectors on
this board. The Com and Printer ports, as well as the other ports, are labeled.
Note: Only TYAN cables will work on this motherboard. If you are using an
existing case with old cables, your system will not function properly. Use only
TYAN-approved cables.
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 had a fairly
uneventful time installing our products. If you did encounter problems, your
dealer will be able to help you, or you can consult one of our many technical
support resources (see page 7).
Frequently Asked Questions
Q: My system sometimes becomes unstable. How should I check the system?
A: The first thing to do is to check and see if you have any device conflict in
address, IRQ, or DMA. If you are using Windows 95, the Device Manager
is a good place to start. Please consult your operating system manual for
details. Second of all, slowing down the memory timing in the BIOS’s
chipset setup section will help the situation, as well. Many memory
modules are not suitable for high performance systems and are probably
the main source of your problem.
Q: What is AGP?
A: AGP (Accelerated Graphics Port) is a new bus architecture for 3D graphics.
The AGP slot eliminates the PCI bandwidth bottleneck by bypassing the
PCI interface and accessing the system memory directly. Currently, theAGP
supports 1X and 2X modes, which yield bandwidths of 264MB/s (at 33MHz
bus speed) and 533MB/s (at 66MHz bus speed), respectively. Compare this
26
Download from Www.Somanuals.com. All Manuals Search And Download.
with the mere 132MB/s (at 33MHz bus speed) that you get with the PCI
bus.
Q: Does my operating system support AGP?
A: Currently, only Windows 98 and Windows NT 5.0 will have built-in support
forAGP. SomeAGP cards require Windows 95 OSR2.1 or a special driver
from Intel. Please check with your graphics vendor for more details.
Q: MyAGP Video has an Intel i740 chipset and gives me problems when I plug
it onto this motherboard, why?
A: There is a known incompatibility with the Intel i740 chipset and the VIA
Apollo chipset on the motherboard. In addition, Windows NT 4.0 does not
support Intel's i740 and older chipsets. Nor does it support VIA apollo
chipset. Such a combination will definitely cause a conflict. One solution
to this problem is to install VIA´sAGPdriver (AGP driver ver. 2.6 or
later). It is included on the Tyan Driver CD, or you can download it from
Q: How do I identify Pin #1 of a 3-pin jumper?
A: There should be a small numeral 1 silkscreened on the board in white next
to pin 1. You can also look on the back side of the board, pin 1 is identified
with a square solder footprint.
Q: Does the motherboard support 2X AGP?
A: Yes, the S1598 supports x2AGP.
Q: What drivers do I install from the CD-ROM provided with the S1598
motherboard?
A: Inside the CD-ROM provided with the Trinity motherboard are Win95,
Win98, and WinNT 4.0 drivers for VIAMVP3 chipset and are located in the
VIAfolder.
The "agpvxd" folder will install driver support for AGP video. NOTE: this
driver is for Win95 users only, however, some Win98 users may need to
install this driver who are having conflicts in Device Manager. There are no
drivers for WinNT 4.0
The "Bmide" folder will install driver support for VIAIDE Busmaster.
NOTE: this driver is for Win95 and WinNT 4.0 users. Win98 users normally
DO NOT have to install this driver; Win98 has built in VIAIDE Bustmaster
driver when installed originally. Install only if you are having conflicts or
exclamation marks with Hard disk controllers in Device Manager

BIOS Configuration
BIOS Configuration
Introduction to Setup
This manual describes theAward EliteBIOS 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 EliteBIOS in your computer is a customized version of an industry-
standard BIOS for IBM PC AT–compatible 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 EliteBIOS 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 EliteBIOS is immediately activated when you first turn on the computer.
The BIOS reads system configuration information in CMOS RAM and begins
30

the process of checking out the system and configuring it through the power-
on 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:
TOENTERSETUPBEFOREBOOTPRESSDELKEY
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.

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 un-
stable.

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 EliteBIOS 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.

BIOS Configuration
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 computer’s 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.

test (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.
SwapFloppyDrive
This field is effective only in systems with two floppy drives. Selecting
40

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.
GateA20 Option
Gate A20 refers to the way the system addresses memory above 1 MB (ex-
tended 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.
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 millisec-
onds.

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 expan-
sion card firmware. If an expansion peripheral in your system contains ROM-
based firmware, you need to know the address range the ROM occupies to
shadow it into the correct area of RAM.

MODEMUseIRQ
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.
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 user-
configurable only in User Defined Power Management mode.
HDDPowerDown
After the selected period of drive inactivity (1 to 15 minutes), the hard disk
drive powers down while all other devices remain active.
48
Download from Www.Somanuals.com. All Manuals Search And Download.
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.
RTCAlarm Resume
When Enabled, you can set the date and time at which the RTC (real-time
clock) alarm awakens the system from Suspend mode.
Primary INTR
A system peripheral signals that it wants to gain the attention of the operating
system by sending an interrupt request. When the system is in Suspend mode,
IRQ activity can cause a Primary or Secondary wake-up. When Primary INTR is
On, the IRQs in the above fields can be configured as Primary, Secondary, or
Disabled.

Primary
The system wakes up fully when it detects IRQ activity.
The system does not wake up, but the interrupt request is
processed. Secondary interrupts are typically
housekeeping devices needed to maintain the system while
Secondary not requiring the use of the rest of the system resources.
For example, IRQ8, the RTC Alarm, is configured as
Secondary by default. Another example might be a
network adapter continually polled by the network.

IRQ-n Assigned to
When resources are controlled manually, assign each system interrupt as one
of the following types, depending on the type of device using the interrupt:
Legacy ISA: Devices compliant with the original PCAT bus
specification, requiring a specific interrupt (such as IRQ4 for serial
port 1).
PCI/ISA PnP: Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.
DMA-nAssigned to
When resources are controlled manually, assign each system DMA channel as
one of the following types, depending on the type of device using the
interrupt:
Legacy ISA: Devices compliant with the original PCAT bus
specification, requiring a specific DMA channel
PCI/ISA PnP: Devices compliant with the Plug and Play standard,
whether designed for PCI or ISA bus architecture.
CPU to PCI Write Buffer
When this field is Enabled, writes from the CPU to the PCI bus are buffered, to
compensate for the speed differences between the CPU and the PCI bus.
When Disabled, the writes are not buffered and the CPU must wait until the
write is complete before starting another write cycle.
PCI Dynamic Bursting
When Enabled, every write transaction goes to the write buffer. Burstable
transactions then burst on the PCI bus; nonburstable transactions do not.
PCI Master 0 WS Write
When this field is Enabled, writes to the PCI bus are executed with zero wait
states.
PCI DelayTransaction
The chipset has an embedded 32-bit posted write buffer to support delay
transaction cycles. Select Enabled to support compliance with PCI specifica-
tion version 2.1.

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 TYAN’s BBS and
from the TYAN 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:
AWDFLASH.EXE
The Flash Memory Writer utility forAward to
Award upgrade.

BIOS Configuration
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.
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 & Pass-
word Reset, page 33).
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 andAUTOEXEC.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.
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:

Error Message:
Type in the whole file name, e.g.A61AW10.BIN, and confirm that you want to
program the BIOS. The utility will then “Blank,” “Erase,” and “Program” the
flash memory on the mainboard with the new BIOS file. You should choose
“Yes” to save the original system BIOS to a floppy diskette before you
program the new BIOS. This leaves you with a backup of your original BIOS in
case you need to re-install it. If you cannot successfully program the new
BIOS file for some reason, re-install your original BIOS from the backup file.
Remember, always reset the CMOS after flashing to a new BIOS (see page 33).
Warning: If you do not successfully install a complete BIOS file in the flash
memory on the mainboard, your system may not be able to boot. If this
happens, it will require service by your system vendor. Follow the instructions
in this section precisely to avoid such an inconvenience.

POST Messages
During the power-on self test (POST), the BIOS either sounds a beep code or
displays a message when it detects a correctable error. Following is a list of
POST messages for the ISA BIOS kernel. Specific chipset ports and BIOS
extensions may include additional messages. An error message may be
followed by a prompt to press F1 to continue or press DEL to enter Setup.
Beep
Currently the only beep code indicates that a video error has occurred and the
BIOS cannot initialize the video screen to display any additional information.
This beep code consists of a single long beep followed by two short beeps.
BIOS ROM checksum error - System halted
The checksum of the BIOS code in the BIOS chip is incorrect, indicating the
BIOS code may have become corrupt. Contact your system dealer to replace
the BIOS.
CMOS battery failed
CMOS battery is no longer functional. Contact your system dealer for a
replacement battery.

CMOS checksum error - Defaults loaded
Checksum of CMOS is incorrect, so the system loads the default equipment
configuration. A checksum error may indicate that CMOS has become corrupt.
This error may have been caused by a weak battery. Check the battery and
replace if necessary.
CPU at nnnn
Displays the running speed of the CPU.
Display switch is set incorrectly.
The display switch on the motherboard can be set to either monochrome or
color. This message indicates the switch is set to a different setting than
indicated in Setup. Determine which setting is correct, and then either turn off
the system and change the jumper, or enter Setup and change the VIDEO
selection.
Press ESC to skip memory test
The user may press Esc to skip the full memory test.
Floppy disk(s) fail
Cannot find or initialize the floppy drive controller or the drive. Make sure the
controller is installed correctly. If no floppy drives are installed, be sure the

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 computer’s 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-bitAGP 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.
The AT was the original form factor of IBM’s PC.
ATAPI (AT Attachment Packet Interface), also known as IDE orATA, 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.
The ATX form factor was designed to replace theAT 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.

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 computer’s 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 key-
board 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. Informa-
tion 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 informa-
tion 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.
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. DMAchannels
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 CPU’s 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 slower 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
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.
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 client’s
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. ISAis 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 system’s 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 alter-
nately 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).
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

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.
