The S1692S Tiger and S1692D Tiger 2 ATX are quality, high performance motherboards designed for Intel’s Pentium II microprocessors.
These motherboards utilize Intel’s 440LX AGP series chipset (also
called AGPset) and support Pentium II CPU speeds of 233MHz to
300MHz.
The S1692S/D mainboards with built-in AGP slot provide 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. The S1692S/D boards are suitable as powerful
workstations, and as internet, intranet, file, network, and database
servers. The Tiger 2 S1692D ATX’s superior dual processor technology
increases performance and productivity drastically for multi-processor
enabled operating systems such as Microsoft Windows NT, Novell
Netware SMP, and SCO Unix.
These integrated system boards achieve high reliability with numerous
features and yet are small enough to be supported in ATX form-factors.
Some of the features included are onboard dual channel PCI
4
UltraDMA 33, onboard floppy controller, and onboard high speed I/O.
The S1692S/D boards are built to be both flexible and expandable. With
I/O and drive controller support built onboard, the five 32-bit PCI BUS
Master and two ISA slots (one shared, seven usable) are available for
add-on expansion cards.
Icons
In order to help you navigate this manual and set up your system, we
have added several icons to our format.
This icon alerts you to particularly important details regarding
!
the setup or maintenance of your system. This icon often
appears next to information that may keep you from damaging
your board or system. While we will often point out the most vital
paragraphs in a chapter, you should always read every word in the text.
Failing to do so can lead to exasperation and expense.
Wherever possible, we have included step-by-step instructions for setting up your system, which are indicated by this
icon. However, it is in your best interest to read an entire
section (and perhaps the entire manual) before you begin to alter the
settings on your motherboard.
INTRO
While we have alerted you to potential dangers in several
places in this manual with this icon, these warnings should not
be regarded as the whole of your safety regimen. Never
forget that computers are electrical devices, and are capable of delivering a burn or shock. Prevent damage to yourself and to your board:
always ensure that your system is turned off and unplugged whenever
you are working with it, and that you are equipped with a static safety
device.

Technical Support
If a problem arises with your system, you should first turn to your
dealer for help. 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 able to 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 yourself (which can have expensive consequences).
If your dealer is unable to assist you:
try our web page – http:// www.tyan.com,
or user newsgroup – alt.comp.periphs.mainboard.tyan.

Board Installation
Unpacking
The mainboard package should contain the following:
S1692S/D mainboard
One IDE 40-pin cable
One 34-pin floppy cable
User’s manual
One retention module (S1692S)
or Two retention modules (S1692D)
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 plugged in and turned off, touch an unpainted
area of the system chassis immediately before handling the mainboard
or any component. Doing so discharges any static charge your body
may have acquired.
10
After opening the mainboard carton, extract the system board–holding
it by its edges–and place it on a grounded anti-static surface, component side up. Inspect the board for damage. Press down on any of the
socket ICs if it appears that they are not properly seated (the board
should still be 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!
Installation
You are now ready to install your mainboard. The mounting hole pattern
of the S1692S/D matches the ATX system board specifications. Your
chassis should be that of a standard ATX mainboard form
factor.
Setting Jumpers
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 not connected.
Jumpers and pins are connected by slipping the black plastic jumper
connector overtop of two adjacent jumper pins. The metal rod inside
the plastic shell bridges the gap between the two pins, completing the
circuit. See the pictures below for examples of “on” and “off” pins and
jumpers.

Windows 95 Users:
!
You may encounter problems with some of the devices in the Intel 82371AB
chipset. Neither the PCI Bridge nor the PCI Universal Serial BUS device
IDs for this chipset (also called PIIX4) are recognized by Windows 95.
This is a software problem, not a hardware problem, and can be easily
remedied by either upgrading to Windows 98 or downloading the 82371AB
patch found at http://www.tyan.com or at ftp://download.intel.com/design/pcisets/busmastr/setupex.exe. (Note: USB requires Windows 95 OSR
2.1 or above; please contact Microsoft for the USB update.)
ONBOARD
CMOS RTC
The 440LX AGPset includes an internal
battery and Real Time Clock circuit. The
RTC provides the date and time for the
system. If the battery is low, it will
prevent your system from POSTing, and
you will not get a display. Normally the
life span of an RTC internal battery is 10
years, but if yours is running low, you will
need to replace it with a new 3V lithium
battery (Duracell DL2032).

Flash EEPROM
The S1692S/D uses flash memory to store BIOS programs. It can be
updated as new versions of the BIOS become available. You can
upgrade your BIOS easily using the flash utility (see page 56).
JP4 determines which type of EPROM is used. This jumper has been
set to match the onboard BIOS chip. The factory default for the
S1692S/D is on pins 1-2. Depending on the type of EPROM used,
some boards will have JP4 on pins 2-3.
Hardware CMOS & Password Reset
If you have been locked out of your system because you forgot your
password or set the CMOS incorrectly, follow the instructions below.
1. Power off the system
2. Set jumper JP3 to pins 2 and 3 (see previous page for
location of JP3).
3. Wait for 2 seconds, then return jumper JP3 to pins 1 and 2.
4. Power on the system again.
By following this procedure, you will erase your password and reset
the CMOS to the BIOS defaults.
DRAM Installation
The S1692S/D uses a 64-bit data path from memory to CPU and can
accommodate up to 1024MB of EDO RAM and 512MB of SDRAM.
SDRAMs (Synchronous DRAMs) are supported in the DIMM slots.
DIMMs must be of the unbuffered variety. The position of the notch
in the DRAM Key Position will tell you whether or not a DIMM is
unbuffered (see figure on the next page). All installed memory will be
automatically detected, so there is no need to set jumpers. The 440LX
AGPset can cache up to 512MB of RAM.

Some details of memory installation:
sOne unbuffered DIMM must be installed for the system to POST.
sThe mainboard supports 8MB, 16MB, 32MB, 64MB, 128MB, and
256MB DIMM modules. 256MB DIMM modules must be EDO.
The table below shows some of the possible memory configurations.
Pentium II processors (233 through 333MHz) can be used on the S1692S/
D. Please refer to page 15 for the correct CPU jumper settings for your
board. Although the S1692DL motherboard is designed as a dual CPU
system, it will also function with a single CPU.
The S1692S/D board provides two slots for Pentium II processors, called
the Pentium II primary and secondary slots. If only one CPU is used, that
CPU should be plugged into the primary slot. When two CPUs are used,
they should be of the same speed and type.
Remember:
sThe CPU is a sensitive electronic component and it can easily be
damaged by static electricity. Do not touch the CPU pins with your
!
fingers.
sWhen installing the CPU into the socket, match the CPU pins to
the socket pins. Note that one corner of the socket’s top is different
from the other three corners. Likewise, one corner of the CPU’s
bottom is different from the other three corners. Line the unique
socket corner up with the unique CPU corner.
sBefore 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.
Active and Passive Processors
Currently, Intel produces two types of Pentium II processors: the active
(or boxed) processor and the passive processor (refer to the pictures on
the following page). These two types of processors are essentially the
same in design; the only difference lies in their cooling methods. The
active processor is equipped with a cooling fan and heat sink, while
the passive processor is equipped with a heat sink alone. Both types of
CPUs provide the user with the same performance, and both types can
be installed in the Pentium II slots on the S1692S/D board. Refer to
page 21 for instructions regarding the installation and removal of
Pentium II processors.

Installation of Pentium II Active (Boxed) Processors
Active processors are equipped with cooling fans. When installing an
active CPU, you also need to connect the cooling fan cable to its
connector.
Installing CPU Retention Modules
1. Installation of a Pentium II active processor requires a CPU
retention module, which is first secured onto the motherboard. (Refer
to the motherboard layout on page 13.)
2. To attach the retention module, place
the motherboard on a flat surface.
3. Locate the key pin on one end of the
Pentium II slot on the board. Then
carefully line up the key notch on the
retention module with the key pin on
the Pentium II slot (the key pin on the
Pentium II slot indicates the correct
Pentium II Slot Connector
and Key Pin
orientation of the CPU).
ONBOARD
21
Chapter 3
4. Drop the retention module down over the
Pentium II slot so that the retention module
sits flat against the motherboard. Tighten the
screws in a clockwise manner to secure the
module to the board. Warning: Do not
overtighten the screws as you may damage
Retention Module
the module and/or the motherboard.
Installing the Active Processor
1. When the retention module is securely installed, you are ready to plug
the CPU into the retention module.
2. Press firmly on the CPU until you hear a
“click.” This clicking sound indicates that the
CPU is fully locked into the retention module.
3. After the CPU is securely seated on the retention module in the Pentium II slot, connect
the CPU’s cooling fan cable to the cooling fan
power connector on the board.
Installing CPU Cooling Fans
1. Locate the cooling fan connectors (3 connectors: FAN1-FAN3) on the
motherboard.
2. Plug the CPU’s cooling fan cable into the cooling fan connector on
the board. Make sure that the black wire of the cable is plugged into
pin 1 of the connector. Refer to pin 1 marked on the layout on page 13.
Pin assignments: pin 1–ground (black), pin 2–12 V (red), pin 3– signal
(yellow).
Installation of Pentium II Passive Processors
Unlike active processors, passive processors are not equipped with
cooling fans. Instead, they are equipped with heat sinks.
22
Each CPU package should contain
the following:
One CPU retention module
One heat sink retention bracket with
Pentium II Passive
CPU Module
mounting locks
Two mounting attach-mounts
One heat sink lock
Installing CPU Retention Modules
1. When installing the CPU retention module, make sure that you have
the appropriate end of the module lined up with the key notch on the
Pentium II slot connector. This will ensure that the module is installed
properly.
2. Before tightening the screws, make certain that the module is flush
against the motherboard. If one end of the module is raised above the
board, check the orientation of the module.
3. Install the module on the board by turning the screws in a clockwise
direction. Do not over-tighten the screws.
ONBOARD
Installing Heat Sink Mounting Brackets
1. The heat sink mount has
two pins on the bottom and
four pins on the top. Notice
that the bottom two pins are
of different sizes. The size of
Heat Sink Mounting
Bracket
the pins and the holes in the
motherboard will determine the correct orientation. A correctly installed
bracket can be verified by making sure that the four pins on the top are
closest to the Pentium II CPU slot.
23
Chapter 3
2. Insert the heat sink mount into the holes on the motherboard. When
the bracket is properly inserted into the holes on the motherboard, you
will hear a clicking noise.
3. Lock the heat sink mount to the board by
inserting the two mounting locks into the pins
of the heat sink mounting bracket which are
now below the mainboard. There will be a
click when the locks are securely fastened.
Installing the Passive Processor
Mounting Locks
1. Align the CPU with the CPU retention module. Make sure the heat
sink is lined up with the heat sink mount bracket. If you put the CPU in
the wrong way, you may damage the CPU, the motherboard, and/or the
CPU socket.
2. Slowly press down on the CPU module until the CPU locks into
place. A clicking noise will be heard when the CPU is locked securely
into the module.
Installing Heat Sink Locks
The heat sink lock has four notches which will correspond to the four
pins on the heat sink mounting bracket. Gently slide the lock between
the heat sink onto the heat sink
mounting bracket until both sides of
the lock are firmly secured. A
Heat Sink Lock
clicking sound will be heard when
the lock is securely fastened to the
heat sink mounting bracket. To
remove the lock from the heat sink mounting bracket, gently press the
ends of the locks inward and pull.
24
Removing Pentium II Passive Processors and CPU Retention
Modules
To remove the CPU, move the locks to the center of the CPU. A click
will be heard when the CPU has been unlocked. Gently pull up on the
CPU, taking care not to bend the motherboard or the CPU retention
module.
Removing Heat Sink Locks
To remove the lock from the retention bracket, gently press the ends of
the locks inward and pull.
Peripheral Device Installation
After all the jumpers on the mainboard have been set, the mainboard
can be mounted into the case. You may then install the display card
and any other peripheral devices that you may have.
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 controllers, you should check the CPU
and all of your devices again before preparing to power on the system.
Connecting the Power Supply
The female power supply connector on the mainboard fits with the
male power supply connector from a 3.3V, 5V, or 12V power supply.
Beware: incorrect installation of the power supply can result in serious
damage to the system board and connected peripherals. Before connecting the leads from the power supply, you should first make sure that
the power supply is unplugged.
ONBOARD
25
Chapter 3
Most male power supply connectors will have twenty wires, seven of
which are black. The black wires will be in the middle of the connector.
The easiest way to orient the connectors properly is to line up the
plastic clip on the male connector with the tab on the female connector.
The plastic clip should be facing the edge of the motherboard.
Align the plastic guide pins on the male connector with their receptacles on the mainboard. You may need to hold the lead at an angle in
order to properly line it up with the onboard connector. Once you have
the guide pins aligned, press the lead into the connector so that the
plastic clip on the lead snaps into place and secures the lead to the
connector. Please see the figure below.

Frequently Asked Questions
Q: Why don’t I get a display after I put in my old DIMM module?
A: The 440LX chipset requires the memory manufacturer to program
an EEPROM chip with SPD (Serial Presence Detection) on the
module in order for the BIOS to program the 440LX’s timing registers
properly. Your DIMM may not have the EEPROM chip on the module,
or the EEPROM may not contain the correct program. Check with
your memory vendor for details. The figure below shows a DIMM
module with an EEPROM chip.

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 detail. 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:I’ve installed Windows NT with one CPU and with the multiproces-
sor kernel. However, when I add a second CPU later, only one CPU is
detected during the Windows NT boot up.
A:AMI BIOS only builds multiprocessor tables according to the
number of CPUs present during Windows NT installation. Therefore,
you must either reinstall NT with two CPUs or use the Windows NT
resources kit to change from a uniprocessor to a multiprocessor
system.
27
Q:How do I know if the system detects the number of CPUs
properly?
A:The AMI BIOS will show a “Pentium–II x2” message during the
memory check to indicate the presence of two CPUs.
Q: How many devices can I hook up to each SCSI channel?
A: You can cascade up to fifteen 16-bit devices per channel and seven
of them can be 8-bit devices.
Q: How do I use the RAID port on my motherboard?
A: The RAID port allows you to put in an Adaptec Array 1000 family
card which will enable the SCSI chip on the motherboard to perform
the RAID function under Netware and Windows NT. RAID 0 is used
for performance purposes (increases SCSI speed), RAID 1 is used for
mirroring (creates two drives with identical information), and RAID 5 is
used for redundancy (if one drive goes down, another will take its
place).
Q: Can I mix EDO DIMM with SDRAM DIMM on this
motherboard?
A: Yes. However, the AGP graphics card performs better with
SDRAM installed on the motherboard because the AGP card can store
the texture map in the system memory.
Q: What is AGP (Accelerated Graphics Port)?
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, the AGP supports 1X and 2X which yields bandwidths of
256MB/s at 66MHz and 512MB/s at 133MHz BUS speeds, respectively. Compare with 132MB/s at 33MHz bus speed with PCI bus.
28
Q: Does my operating system support AGP?
A: Currently, only Windows 98 and Windows NT 5.0 will have built-in
support for AGP. Some AGP cards require Windows 95 OSR2.1 or a
special driver from Intel. Please check with your graphics vendor for
more detail.

Entering Drive Parameters
You can also enter the hard disk drive parameters yourself. The drive
parameters are as follows:
ParameterDescription
TypeThe number for a drive with certain identification parameters.
CylindersThe number of cylinders in the disk drive.
HeadsThe number of heads.
The actual physical size of a sector gets progressively smaller as the
track diameter diminishes. Yet each sector must still hold 512 bytes.
Write Precompensation
Landing Zone
Sectors
Capacity
Write precompensation circuitry on the hard disk compensates for the
physical difference in sector size by boosting the write current for
sectors on inner tracks. This parameter is the track number on the
disk surface where write precompensation begins.
This number is the cylinder location where the heads normally park
when the system is shut down.
The number of sectors per track. MFM drives have 17 sectors per
track. RLL drives have 26 sectors per track. ESDI drives have 34
sectors per track. SCSI and IDE drives have even more sectors per
track.
The formatted capacity of the drive is the number of heads times the
number of cylinders times the number of sectors per track times 512
(bytes per sector).

channel. The settings are PnP or ISA/EISA . The Optimal and FailSafe default settings are PnP.
These options specify the bus that the specified IRQ line is used on.
These options allow you to reserve IRQs for legacy ISA adapter cards.
These options determine if AMIBIOS should remove an IRQ from the
pool of available IRQs passed to devices that are configurable by the
system BIOS. The available IRQ pool is determined by reading the
ESCD NVRAM. If more IRQs must be removed from the pool, the
end user can use these options to reserve the IRQ by assigning an ISA/
EISA setting to it. Onboard I/O is configured by AMIBIOS. All IRQs
used by onboard I/O are configured as PCI/PnP. IRQ12 only appears if
the Mouse Support option in Advanced Setup is set to Disabled. IRQ14
and 15 will not be available if the onboard PCI IDE is enabled. If all
IRQs are set to ISA/EISA and IRQ14 and 15 are allocated to the
onboard PCI IDE, IRQ9 will still be available for PCI and PnP devices,
because at least one IRQ must be available for PCI and PnP devices.
The settings are ISA/EISA or PCI/PnP. The Optimal and Fail-Safe
default settings are PCI/PnP.

Chapter 4
Flash Writer Utility
The AMI Flash Writer Utility is now included in the AMIBIOS, and so
it is simpler to upgrade the BIOS of your mainboard. The system BIOS
is stored on a flash EEPROM ROM chip on the mainboard which can
be erased and reprogrammed by following the directions below.
1. Rename the BIOS file that you have downloaded to “amiboot.rom”
and copy it on to a floppy disk.
2. Insert the floppy disk with the BIOS upgrade into the A: drive.
3. Turn the power off.
4. While holding the <Ctrl> and <Home> keys, turn the power on. The
system will begin to read from the A: drive, and write the BIOS
information contained on the floppy disk in that drive to the EEPROM
ROM chip. When the BIOS has been totally reprogrammed, you will
hear three beeps and the system will reboot with the new BIOS in
operation.
5. If the system does not reboot in three minutes, power down the
system, wait a few seconds, and then turn the power back on again.
