1. Introduction
1.1 Overview
The S1668 is a quality, high performance dual processor mainboard based
on the powerful Intel Pentium Pro microprocessors. This mainboard is
designed around the latest and fastest Intel 440FX chipset and can support
CPU speeds of 150MHz through 200MHz.
The S1668 supports EDO memory, Burst EDO, ECC and memory parity
checking.The S1668's PCI Local Bus provides high performance capabili-
ties that are ideal for a wide range of demanding applications such as:
CAD, CAM, CAE, networking, multi-user environments, database man-
agement, desktop publishing, image processing and 3D animation.
This integrated system board achieves the highest reliability and features
the industry standard "ATX" form factor. Some of the features included
are: on-board dual channel PCI IDE, on-board floppy controller, on-board
high speed I/O, Universal Serial Bus and on-board PS/2 mouse connector.
Flexibility and expandibility have been designed into the S1668. With I/O
and drive controller support built on-board, the five PCI and three ISA
(One ISA and one PCI as a shared slot) slots are free for add-on expansion
cards. With eight SIMM sockets, the S1668 can provide a very
flexible memory configuration of 8MB to 1024MB of RAM. With the
S1668's support for dual Pentium Pro processors, you can start a system
with just one CPU, and later add another, when more processing power is
required.

2. Board Installation
2.1 Unpacking
The mainboard package should contain the following:
S1668 Mainboard
One IDE 40 pin cable
One 34 pin floppy cable
User's Manual
Optional VRM(Voltage Regulator Module)
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.
With the power supply pluged in and turned off touch an unpainted area of
the system chassis imedietly before handling the mainboard or any compo-
nent. Doing so discharges the static charge your body may have built.
After opening the mainboard carton, extract the system board holding it by
its edges ,and place it only on a grounded anti-static surface, component
side up. Inspect the board for damage. 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 anti-static mat. Do not touch the bottom of the board.
DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN
DAMAGED!
2.2 Installation
You are now ready to install your mainboard. The mounting hole pattern of
the S1668 matches the ATX system board spec. It is assumed that the
chassis is for a standard ATX mainboard form factor.

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
S1668 provides a 4-Pin header (J43) 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. The Intel 44FX chipset doesn't support a de-turbo
mode, but the S1668 has a connector (J47) for the cable that may come has
a connector (J47) for the cable that may come with the case.with the case.
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
J42 in the correct direction.

3.7 Hardware Reset Switch Connector Installation
The RESET switch on your cases' display panel provides users with the
HARDWARE RESET function 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
J45.
3.8 Flash EEPROM-Jumper J32
The S1668 uses flash memory to store BIOS data. It can be updated as
new versions of the BIOS becomes available. The flash utility will guide
you through the process step by step. If your system is functioning properly,
you may want to forego updating your BIOS in the event the new one
causes problems with your existing hardware and software.
J32 determines which type of EPROM is used. This jumper has been set to
match the on board BIOS chip. The factory default for the S1668 is on pins
1-2.
Refer to chapter 6 for Flash EEPROM 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 pass-
word or set the CMOS incorrectly, follow the instructions below.
a. Power off the system
b. Short jumper J41.
c. Wait for 5 seconds then remove the jumper from J41.
d.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 defaults.

3.10 DRAM Installation
The S1668 uses a 64-bit data path from memory to CPU and can
accommodate up to 1024 MB of RAM. The mainboard supports
standard, EDO (Extended Data Out) and ECC(Error Correcting Code)
72 pin SIMMS . All installed memory will be automatically detected so
there is no need to set jumpers.
SIMM modules must be installed in pairs.
Each pair of SIMMs must be of the same size and type.
The mainboard supports 1, 2, 4, 8, 16x32 or 32MBx32 SIMMS.
The table on the following page shows some of the available memory
configurations.
Voltage ID for Older Pentium Pro CPU's: J10 and J20
Most Pentium Pro CPU's will program the VRM to output
the correct voltage it requires, so these jumper are not important
and should be left open. Some early versions of the Pentium Pro
cannot program the VRM so you have to set these jumper manually.
J10 and J20 each have eight pins and are numbered as follows.

3.11 CPU Installation
Many types of Pentium Pro (150 thru 200 MHz) CPUs can be used on
the S1668. Please refer to the previous pages for the correct CPU jumper
settings for your board.
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.
When installing the CPU into the socket, match the CPU pins to the
socket pins.
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.
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
of the CPU 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 in the down position.

3.12 VRM Installation
The VRM is required for the Pentium Pro to work. The CPU will
program the VRM for the correct voltage needed. No jumper settings
are needed, just install the VRM into the VRM socket nearest the
CPU that is being installed. The VRM can only fit in the socket one
way so there is no danger of installing it incorrectly. Not all VRM's
will work in the S1668. Make sure you purchased a qualified VRM.
VRM socket 0 is for CPU socket 0.
VRM socket 1 is for CPU socket 1.
3.13 Peripheral Device Installation
After all the jumpers on the mainboard have been set, then it can be mounted
into the case. Then proceed to install 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.
3.14 Connecting the Power Supply & On/Off Switch
The system power supply connectors on the mainboard is for a
standard ATX power supply. It can only be plugged in one way and
should install in easily.
ATX cases have an on/off switch that can be used to turn on or off
the ATX powersupply without having to use the switch that is on
the back of the powersupply.Use jumper J1 is for the on/off button from the
system case.

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

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 using 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.

5.0 Flash Writer Utility
You can upgrade the BIOS of your mainboard by using a "Flash
MemoryWriter"(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 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 MemoryWriter utility for
Award to Award upgrade.
AMIFLASH.COM -The Flash Memory Writer utility for
AMI to AMI upgrade.
README
-A text file of instructions
*S62AWXX.BIN
-XX-A2-digit version number.
Flash memory writer records (or ‘programs’) a new BIOS
onto the flash memory chip.You cannot upgrade anAward
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"extension.
S1668-ATXD-o0w01nlohattdpf:r/o/wmwWww.twya.Sno.cmoamnuals.co3m6. All Manuals Search And Download.
To reprogram the System BIOS, you must first do the following:
1. Check jumper J32
The S1668 uses a 5V Flash EPROM so jumper J32
should be left in the default postion on pins 1 and 2. This
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 withWindows
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 orAUTOEXEC.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 andAUTOEXEC.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 suc-
ceeded. If it displays a warning message about the CPU
mode, you will have to try again.
S1668-ATXD-o0w01nlohattdpf:r/o/wmwWww.twya.Sno.cmoamnuals.co3m7. All Manuals Search And Download.
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
backup of the support floppy disk. Make sure the new BIOS file
isinthe same directory as the FMWutility.
To run FMW, change to the “Flash” directory if you are not al-
ready in it. Type “Awdflash” at the DOS command line and press
the <Enter> key. The following screen will appear.

Date:4/13/95
File Name to Program:
Error Message:
Type in the whole file name, e.g. A62AW10.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 re-
install 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.
