User's Manual  
 
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.  
Remember to take a look at Tyan Computers web site located at  
products along with FAQ's, distributors list, drivers and CMOS setting  
explanations.

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.  
S1668-ATXD-o0w01nlohattdpf:r/o/wmwWww.twya.Sno.cmoamnuals.co1m1. All Manuals Search And Download.  
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.

4. BIOS Configuration  
Award's BIOS has a built in setup program that allows the user to modify  
the basic system configuration. This type of information is stored in the  
battery-backed CMOS SRAM. Entering incorrect information or for-  
getting your password can lock you out of your system.(refer to 3.15  
for resetting of CMOS)  
4.1. Entering Setup

detected during power up.  
All errors  
No errors  
Whenever the BIOS has detected a non-fatal error, the  
system will be stopped and you will be promted.  
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.  
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.  
S1668-ATXD-o0w01nlohattdpf:r/o/wmwWww.twya.Sno.cmoamnuals.co2m3. All Manuals Search And Download.  
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.

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.

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.

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.

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.
