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.

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.
