1. Introduction

1.1 Overview

The S1468 is a quality, high performance mainboard based on the
powerful Intel Pentium microprocessors. This mainboard is designed
around the latest and fastest Intel Triton chipset and can support CPU
speeds of 75MHz through 166MHz.

The S1468's PCI Local Bus provides high performance capabilities that
are ideal for a wide range of demanding applications such as: CAD,
CAM, CAE, networking, multi-user environments, database management,
desktop publishing, image processing and 3D animation.

This integrated system board achieves the highest reliability and yet is
small enough for all of its features to be supported in a "Baby-AT" form­factor. Some of the features included are: on-board dual channel PCI
IDE, on-board floppy controller, on-board high speed I/O, and support for
either pipeline-burst or standard asynchronous SRAM.

Flexibility and expandibility have been designed into the S1468. With I/O
and drive controller support built on-board, the four PCI and five ISA
(One ISA and one PCI as a shared slot) slots are free for any add-on
expansion cards. Unlike most Triton based mainboards that have only
four SIMM sockets, the S1468 supports six SIMM sockets for a more
flexible memory configuration. The S1468's VRM (Voltage Regulator
Module) will support future Pentium CPU's that may require less Voltage
than the current Pentiums.

2. Board Installation

2.1 Unpacking

The mainboard package should contain the following:

wS1468 Mainboard
wOne IDE 40 pin cables
wTwo serial cables

wwOne parallel cable

wOne 34 pin floppy cable
wUser's Manual

The mainboard contains sensitive electric components which can be easily
damaged by static electricity, so the mainboard should be left in its original
packaging until it is ready to be installed.

Unpacking and installation should be done on a grounded anti-static mat.
The operator should be wearing an anti-static wristband, grounded at the
same point as the anti-static mat.

Inspect the main board carton for obvious damage. Shipping and handling
may cause damage to your board. Be sure there are no shipping and han­dling damage on the board before proceeding.

After opening the mainboard carton, extract the system board and place it
only on a grounded anti-static surface, component side up. Again inspect
the board for damages. Press down on all of the socket IC's to make sure
that they are properly seated. Do this only with the board placed on an anti­static mat.

DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN
DAMAGED!

3.3 CMOS RTC

CMOS RTC includes an internal battery and Real Time Clock circuit. It
provides the date and the time for the system. Normally the life span of a
RTC internal battery is 10 years. When replacing, you should use the same
model.

3.4 Speaker Connector Installation

S1468 provides a 4-Pin header (J45) to connect the speaker. The polarity
can go either way.

3.5 Turbo Switch

The front panel on your case may have a turbo switch to control system
speed when slower program execution is required for software developed
in the old XT days.

You can connect the chassis turbo switch to J47 on the mainboard. The
Triton chipset doesn't support a hardware turbo function so this switch will
only turn on or off the turbo LED. You need to use the hot key of
<Ctrl> + <Alt> + <-> for slow speed and <Ctrl> + <Alt> + <+> for high
speed.

3.6 Turbo LED Connector Installation

The TURBO LED on the front case panel can indicate the current speed
status of the system. The TURBO LED connector should be installed to
J50 in the correct direction.

12S1468-001-01

3.7 Hardware Reset Switch Connector Installation

The RESET switch on your cases' display panel provides users with the
HARDWARE RESET functinon which is the same as power on/off. The
system will do a cold start after the RESET switch is pushed by the user.
The RESET switch is a 2 pin connector and should be installed on jumper
J49.

3.8 Flash EPROM-Jumper J42, J43 and J44

The S1468 uses flash memory to store BIOS programs. It can be updated
as new versions of the BIOS becomes available. The flash utility will guide
you through the process step by step.

J42, J43,and J44 determines which type of EPROM is used. These jump­ers have been set to match the on board BIOS chip. The factory default for
the S1468 is on pins 1-2. Depending on the type of EPROM used, some
boards will have J42 on pins 2-3.

Refer to chapter 6 for Flash EPROM upgrade procedures.

3.9 Hardware CMOS & Password Reset

(The following steps are valid provided the board has a DS12887A RTC)

If you have been locked out of your system because you forgot your pass­word or set the CMOS incorrectly, follow the instructions below.

a. Power off the system

b. Short jumper J41.

d. Wait for 5 seconds then remove the jumper from J41.

e.Then power on the system again.

By doing the above procedures, your password will be erased and the CMOS
will be reset to the BIOS default.

13S1468-001-01

3.10 DRAM Installation

The S1468 uses a 64-bit data path from memory to CPU and can
accommodate up to 128 MB of RAM. The mainboard supports both
standard and EDO (Extended Data Out) 72 pin SIMMs. All installed
memory will be automatically detected so there is no need to set jumpers.

wSIMM modules must be installed in pairs.

wEach pair of SIMMs must be of the same size and type.

wThe mainboard supports 1, 2, 4 and 8MBx32 SIMMS.

wBank 0 only supports single sided SIMMs.

wBank 1 and 2 can use either double or single sided SIMMs.

wTwo SIMMs must be installed in any bank for the system to POST.

wThe table below shows some of the available memory configurations.

Bank 1 Bank2 Bank0 Total Memory
1MBx32 none none 8MB
1MBx32 1MBx32 none 16MB

14S1468-001-01

3.11 CPU Installation

Several types of CPUs (75 thru 166 MHz) can be used on S1468.
Please refer to the previous pages for the correct CPU jumper settings for
your board.

w The CPU is a sensitive electronic component and it can be easily
damaged by static electricity. Do not touch the CPU pins with your
fingers.

w When installing the CPU into the socket, match the CPU pins to the
socket pins.

w Before the CPU is installed, the mainboard must be placed on a flat
plane in order to avoid being broken by the pressure of CPU insertion.

w A cooling fan and heat sink assembly is required to protect the
CPU from being damaged.

1. Make sure the ZIF socket lever is up. To raise the lever, pull it out
to the side a little and raise it as far as it will go. The top plate will
slide back.

2. Align the CPU and socket Pin 1 corners. The pins on the bottom
should align with the rows of holes in the socket.

3. Insert the CPU in the socket. It should insert easily. If it does
not, adjust the position of the lever a little.

4. Press the lever down. The top plate will slide forward. You will
feel some resistance as the pressure starts to secure the CPU in
the socket. This is normal and will not damage the CPU.
When the CPU is installed, the lever should snap into place at the
side of the socket.

15S1468-001-01

3.12 Upgrading Cache Memory

The S1468 can support either standard SRAM or synchronous pipeline

burst SRAM. The standard SRAM configuration would use either eight
pieces of 32Kx8(256KB cache) or eight pieces of 64Kx8(512KB cache).

For the synchronous pipeline burst cache configuration, a "COAST
Module" is plugged into the "COAST Module" connector that is located
between the CPU and the standard SRAM socket. To enable the
"COAST Moduel", you must set the jumpers to pins 1-2 for J28, J29, J30
and J31.

wRefer to page 9 for the cache jumper settings.

wWhen using the "COAST Module", the standard SRAM sockets must

be empty and the Tag RAM socket must be empty.

wThe "COAST Module" pipline burst cache unit comes in either 256KB
or 512KB sizes and has a built in Tag RAM chip.

wThe "COAST Module" will only fit in the "Coast Socket" one way and
should install easily.

wWhen upgrading standard SRAM to 512KB, you will need to set the
jumpers and use eight 64Kx8 chips.

wwThe tag RAM chip doesn't need to be changed when upgrading to
512KB of standard SRAM.

16S1468-001-01

3.13 Understanding The Different Clock Speeds

The following chart shows the different CPU, mainboard and PCI fre­quencies. As you may have noticed, all the Intel Pentium CPUs use an
internal clock multiplier(x3, x2.5, x2 or x1.5 Motherboard speed).

Pentium Mainboard PCI Bus
Internal Clock Clock Clock
75 MHz 50 MHz 25 MHz
90 MHz 60 MHz 30 MHz
100 MHz 66.67 MHz 33 MHz
120 MHz 60 MHz 30 MHz
133 MHz 66.67MHz 33 MHz
150 MHz 60 MHz 30 MHz
166 MHz 66.67 MHz 33 MHz

In the table above, the 50, 60 and 66.67 MHz figures are oscillator speeds
that establish the external clock speed. The PCI Bus clock speed is fixed at
one half of the mainboard clock speed. The 150MHz Pentium when set for

2.5x mode will achieve a 30MHz PCI bus speed but if it is set for 3x mode
you will get a slower 25MHz PCI bus speed.

17S1468-001-01

3.14 Peripheral Device Installation

After all the jumpers on the mainboard have been set, the it can be mounted
into the case. Then proceede in installing the display card and any other
peripheral devices.

If a PCI-Bus interface card is to be installed in the system, any one of the
four PCI-Bus slots can support either a Master or a Slave device.

After installing the peripheral controller, the user should check everything
again, and prepare to power-on the system.

3.15 Turbo / Non-Turbo hotkeys

press <Ctrl> + <Alt> + <-> : turn off turbo function.
press <Ctrl> + <Alt> + <+> : turn on turbo function.

18S1468-001-01

3.16 Connecting the Power Supply

The system power supply connectors on the mainboard is for a 5 volt
power supply. Incorrect installation of the power supply could result in
serious damage to the system board and connected peripherals.

leads. Each lead has six wires, two of which are black.

Orient the connectors so the black wires are in the middle of the

5V power supply.

Caution: Some power supplies also include "3V" connectors. The
connection wires normally have two colors with 3 black wires on
one side. Please be very careful. Don't to use the wrong connec­tor.

19S1468-001-01

Align the plastic guide pins on the lead cables to their receptacles on the
mainboard. You may need to hold the lead at an angle to line it up.Once
you have the guide pins aligned, press the lead connector so that the
plastic clips on the lead snap into place and secure the lead to the connec­tor.

ww Video

This category detects the type of graphics adapter used for the primary
display system. It must match your video display card and monitor. Al­though secondary monitors are supported, you do not have to select that
type in setup.

EGA/VGA Enhanced Graphics Adapter/Video Graphics Array.

For VGA,SVGA, or PGA monitor adapters.
CGA 40 Color Graphics Adapter, power up in 40 column mode.
CGA 80 Color Graphics Adapter, power up in 80 column mode.
Mono Monochrome adapter, includes hi-res monochrome.

ww Halt On

The category determines whether the computer will stop if an error is
detected during power up.

No errors Whenever the BIOS has detected a non-fatal error, the

system will be stopped and you will be promted.
All errors The system boot will not be stopped for any errors that

are detected.
All, but Keyboard The system boot will not stop for a keyboard error;it

will stop for all other errors.
All, but Diskette The system boot will not stop for disk errors; it will

stop for all other errors.
All, but Disk/Key The system boot will not stop for a keyboard or disk

error; it will stop for all other errors.

ww Memory

The category is for display-only and it is determined by POST Power On
Self Test of the BIOS.

Base Memory

The POST of the BIOS will determine the amount of

base (or conventional) memory installed in the system.

The value of the base memory is typically 640K.

Extended Memory

The BIOS determines how much extended memory is

present during the POST. This is the amount of

memory located above 1MB in the CPU's memory

address map.

27S1468-001-01

Expanded Memory

Expanded Memory (EMS) defines a 64 K page frame in

the area between 640K and 1Mb containing four 16K pages

that are windows into the EMS memory. Programs issue

requests to the EMS manager to switch the page to any

part of EMS memory. Extended memory can be converted

to emulate EMS by useing a memory manager such as

EMM386 that ships with Windows and DOS.

Other Memory

This refers to memory located in the 640K to 1024K ad

dress space. This memory can be used for different

applications. DOS uses this area to load device drivers to

keep as much conventional memory free for application

programs as possible.

ww Chipset Features
The DRAM timings can be altered from the default to optimize system

performance. Be aware though that these settings are sensitive to the
type and speed of DRAMs being used and can cause lockups or data
lost if set incorrectly. The default settings should work with most
DRAMs.

w DRAM RAS# Precharge Time

DRAM must continually be refreshed or it will lose its data. Normally,
DRAM is refreshed entirely as the result of a single request. This option
allows you to determine the number of CPU clocks allocated for the
Row Address Strobe to accumulate its charge before the DRAM is
refreshed. If insufficient fime is allowed, refresh may be incomplete
and data will be lost. A lower setting may increase performance.
The default value is 4 clocks.

wwDRAM R/W Leadoff Timing

This sets the number of CPU clocks allowed before reads and
writes to DRAM are performed. The default of 8/6 would set the
leadoff timing for reads to eight clocks and writes to six clocks.
A lower setting may increase performance.
The default value is 8/6.

ww DRAM RAS to CAS Delay
When DRAM is refreshed, both rows and columns are addressed

separately. This option allows you to determine the timing of the
transition from Row Address Strobe (RAS) to Column Address
Strobe(CAS). A lower setting may increase performance.
The default is 3 cpu clock delay.

32S1468-001-01

wwDRAM Read/Write Burst Timing
This sets the timing for Burst mode reads from DRAM. Burst read and

write request are generated by the CPU in four separate parts. The
"x" is the leadoff cycle and is determined by the chipset and the memory
timing. The remaining four numbers is the actual data cycles. The lower
the timing numbers, the faster the system will address memory.
The default for read burst timing is x2222.

The default for write burst timing is x3333.

ww System BIOS Cacheable
When enabled, accesses to the system BIOS ROM addressed at

F0000H-FFFFFH are cached. Enable this for best performance under
DOS/Windows or Windows95. When using operating systems that do
not access the BIOS (Unix, OS/2, NT, etc...) this setting can be
disabled.
The default is enabled.

wwVideo BIOS Cacheable
As with caching the system BIOS above, enabling the Video BIOS

cache will cause access to the video BOS addressed at C0000h to
C7FFFFh to be cached.
The default is enabled.

ww8 bit I/O Recovery Time
The recovery time is the length of time measured in CPU clocks, which

the system will delay after the completion of an I/O request. This delay
takes place because the CPU is operationg so much faster than the
I/O bus that the CPU must be delayed to allow for the completion of the
I/O request. This option allows you to determine the recovery time
allowed for 8 bit I/O.
The default is 1 clock cycle.

ww16 bit I/O Recovery Time
This option allows you to determine the recovery time allowed for 16 bit

I/O.
The default is 1 clock cycle.

33S1468-001-01

wwMemory Hole at 15M-16M
Some ISA cards may not function correctly when more than 16MB of

RAM is installed. If this is the case, then enable this option. Most ISA
should work fine with this option disabled.
The default is disabled.

wwIDE HDD Block Mode
This option allows the hard disk controller to use fast block mode

transfer to and from the hard disk drive. The hard drive must support
block mode transfer for this option to be enabled.(Most new drives do.)
The default is enabled.

wwIDE Primary/Secondary Master/Slave PIO
Rather than have the BIOS issue a series of commands to effect a

transfer to or from the disk drive, PIO(Programmed Input/Output)
allows the BIOS to tell the controller what it wants and lets the
controller and the CPU perform the complete task themselves. This
method is simpler, more efficeint and faster. This BIOS supports five
modes (0 thru 4) and can be set by the user or set to Auto detect.
The default is Auto.

wwOn-Chip Primary/Secondary PCI IDE
This option enables or disables the on board PCI IDE controllers.

The default is enabled.

wwPCI Concurrency
When enabled, the CPU can run concurrently with a PCI bus mastering

peripheral. This achieves significant data transfer rate improvements
without splitting resource utilization between the CPU and bus mastering
device.
The default is enabled.

wwPCI Streaming
Streaming is an advanced bus cycle type and can increase data transfer

rate on the PCI bus.
The default is enabled.

34S1468-001-01

wwPCI Bursting
When enabled, all read and write data transfers over the PCI bus are

burst transfers.
Default is enabled.

wwOnboard FDC Controller
This option lets you enable or disable the onboard floppy controller.

The default is enabled.

wwOnboard Serial Port 1/2
This option lets you select how this port will be addressed. The options

are Com1 thru Com4 or disabled.
The default is Com1for port 1 and Com2 for port 2.

wwOnboard Parallel Port
This option lets you select the LPT port address. Options are 3BCh,

378h, 278h or Disabled.
The default is 278h.

wwParallel Port Mode
This option lets you select which mode the parallel port will run in. The

options are Normal, EPP, ECP, or ECP + EPP.
The default is EPP.

6.0 Flash Writer Utility

You can upgrade the BIOS of your mainboard by using a "Flash
Memory Writer"(FMW) utility. This utility can be downloaded from the
factory's BBS(Consult your system vendor for the phone #). The
system BIOS is stored on a 'flash' EPROM ROM 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 for

Award to Award upgrade.

AMIFLASH.COM -The Flash Memory Writer utility for

AMI to AMI upgrade.

README -A text file of instructions
*S68AWXX.BIN -XX-A 2-digit version number.

Flash memory writer records (or ‘programs’) a new BIOS
onto the flash memory chip. You cannot upgrade an Award
BIOS to a AMI BIOS or a AMI BIOS to an Award BIOS.

*This file name is subject to change and can have either a "bin" or a
"rom" extention.

53S1468-001-01

To reprogram the System BIOS, you must first do the following:

1. Check jumpers J42, J43, and J44.

The S1468 uses a 5V Flash EPROM so these three jumpers
should be left in the default postion on pins 1 and 2. These
jumper should never be moved.

2. Make sure the CPU is running in ‘real mode’.

FMW will not run if the CPU is operating in a protected or
virtual mode. This means that you can not run it with Windows
running or with any memory manager software. You must
disable any memory manager first. The easiest way to do this
is to:

a. Boot your system from a bootable floppy disk with no
CONFIG.SYS or AUTOEXEC.BAT files, and then run Flash
Memory Writer 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.

b. If you are using MS-DOS 6.x, you can use the feature that
allows you to bypass the CONFIG.SYS and AUTOEXEC.BAT

file. You do this while pressing <F5> while the “Starting MS-

DOS...” line is on the screen.

There are other ways to accomplish the same result. The main
point is to make sure no memory managers are running. If you
are not sure, try running FMW. If it runs, then you have suc­ceeded. If it displays a warning message about the CPU
mode, you will have to try again.

54S1468-001-01

Once you have satisfied the two requirements mentioned above,

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
backupof the support floppy disk. Make sure the new BIOS file
is in thesame directory as the FMW utility.

To run 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 following screen will appear.

6.1 The Flash Memory Writer Utility Screen (Award)

FLASH MEMORY WRITER V3.0

Copyright (C) 1993, AWARD Software Inc.,

For Triton-2A59CT51 Date:4/13/95

File Name to Program:

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 then ‘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 re­install it. This option is highly recommended. If you can not sucessfully
program the BIOS file for whatever reason, re-install you original BIOS
from the backup file.

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 requirements and instructions in this section precisely to aviod
inconvenience.
