Introduction
Overview
The S1832DL Tiger 100 is a quality, high performance mainboard designed for
dual Intel Pentium II microprocessors. This mainboard utilizes the Intel 440BX
AGPset and can support CPU speeds of 233MHz through 450MHz, and host
bus speeds of 66MHz to 100MHz.
The S1832DL mainboard, with built-in AGP slot, provides 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.
This integrated system board achieves high reliability with numerous features
and yet is small enough to be supported in an ATX form factor. Some of the
features included are onboard dual channel PCI PIO, Bus Master IDE and
UltraDMA/33, onboard floppy controller, and onboard high speed I/O.
Flexibility and expandability have been designed into the Tiger 100. With I/O
and drive controller support built onboard, the one AGP slot, five PCI and two
ISA slots (one shared, seven usable slots) are free for numerous add-on
expansion cards.

Technical Support
If a problem arises with your system, you should turn to your dealer for help
first. 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 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 do so yourself (which can
have expensive consequences).
If your dealer is unable to assist you,

procedure
What’s the first thing I should do?
The first thing you should do is read this user’s manual. It contains important
information which will make configuration and setup much easier.
Here are some precautions you should follow when installing your mother-
board:
(1) Ground yourself properly before removing your motherboard
from the antistatic bag. Unplug the power from your computer
and then touch any metal part on the computer case. (Or wear a
grounded wrist strap.)
(2) Hold the motherboard by its edges and do not touch the bottom of
the board.
(3) Avoid touching motherboard components, IC chips, connectors,
and leads.
(4) Avoid touching pins of memory modules and chips.
(5) Place motherboard on a grounded antistatic surface or on the
antistatic bag.
DO NOT APPLY POWER TO THE BOARD IF IT HAS BEEN DAMAGED!
!
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. Remember, don’t take any electronic device out of its
protective bag until you are ready to actually install it into the computer case.
If you do not ground yourself, you risk zapping the motherboard or adapter
card. Subsequent problems may not arise immediately because electrostatic
discharge damage, unlike physical damage, causes the device to fail over time.
important!
Install the motherboard into your case.
Follow the instructions provided by the case manufacturer for proper installa-
tion guidelines. TYAN recommends that you use only one screw to hold down
the motherboard. The rest of the mounting holes should be used for the plastic
standoffs. If your case does not have a hole for a standoff, simply cut off the
bottom of the plastic standoff so that the flat portion rests on the metal. The
adapter cards and the screws holding them down will keep your board flat. The
fastening screw should not short any of the traces on the motherboard. Make
certain that you do not overtighten the screw, as it will damage the mother-
board and possibly break internal traces in the surrounding area. The hole you

should use is located at the top-center of the board where the adapter cards
are fastened to the case.
Plug in the power connector as shown.
The photos below show the ATX power connector before (Figure 1) and after
(Figure 2) it has been plugged in.
Figure 1
Figure 2
The plastic clip on the power connector should lock over the plastic tab on the
onboard connector. You shouldn’t be able to plug the power connector in any
other way but just to be safe, make sure it looks like Figure 2 above. Make
certain that you do not miss any pins because, if you do, you will void your
warranty and cause damage to yourself or your motherboard when you turn
the system on. After connecting the power, make sure the connector is seated
firmly into its socket so it will not become loose or fall off when the computer
is jostled or moved. Note: Tyan recommends using an ATX power supply that
conforms to industry standard revision 2.01.

Next, connect your IDE cables (if you’re using IDE hard drives).
Figure 3
The colored stripe on the cable should face toward the top of your chassis, or
toward the big white B printed on the motherboard.
In Figure 3 you can see
how the IDE cables should
look when they are
connected to your hard
drive. Notice how Pin 1
(denoted by a red stripe) is
connected so that it is next
to the power connector of
the drive. In most cases,
this is the proper way of
connecting your IDE cable
to the hard drive. Figure 4
shows the IDE cable
properly connected to the
motherboard.

Some symptoms of incorrectly installed HDDs are:
•
•
•
•
•
Hard disk drives are not auto-detected: may be a Master/Slave
problem or a bad IDE cable. Contact your vendor.
Hard Disk Drive Fail message at bootup: may be a bad cable or
lack of power going to the drive.
No video or beeps on bootup: usually means the cable is on
backwards.
Hard drive lights are constantly on: bad IDE cable or defective
drives/motherboard. Try another HDD.
Hard drives do not power up: check power cables and cabling.
May also be a bad power supply or IDE drive.
Now that you have installed your IDE drives, your floppies are next.
Figure 5
Pin 1 on the floppy cable is usually denoted by a red or colored stripe down
one side of the cable (see Figure 5). Most of the current floppy drives on the
market require that the colored stripe be positioned so that it is right next to
the power connector. In most cases, there will be a key pin on the cable which
will force you to connect the cable properly.
Drive A: is usually attached to the end of the cable with the twist in it. Drive B:
is usually connected to the middle of the cable. Refer to your installation
instructions or call your dealer if you are unsure about attaching floppy drives.
14

Refer to Figure 5 on the previous page for a detailed anatomy of the floppy
cable. Remember, you can only have 2 floppy drives connected at any given
time.
The color stripe on the cable should face toward the top of your chassis, or
toward the big white B printed on the motherboard. Please refer to your
documentation for proper installation, or see Figure 4 on page 13.
Some symptoms of incorrectly installed floppies are:
•
Floppy drives are not detected: usually caused by faulty cables,
backward cables, or a bad floppy or motherboard. Try another
single floppy drive to verify the problem or try another cable. Also,
check to see if the onboard floppy is enabled in the BIOS.
Floppy Drive Fail message at bootup: the cable, floppy, or
motherboard may be faulty. Try another cable or floppy drive to
verify.
Light on the floppy is on constantly: a dead give-away that the
cable is on backwards. Reverse the cable at the motherboard end
and try again.

Next are the Com and Printer ports.
Warning: When plugging in your keyboard and mouse, or when plugging
anything into a serial or Com port, make sure that the power is off. Connecting
important! these devices and ports while the power is on is called “hot plugging,” and
may damage your system.

Note: Only TYAN cables will work on this motherboard. If you are using an
existing case with old cables, your system will not function properly. Use only
TYAN-approved cables.
Connecting the USB and PS/2 ports.
This board includes ports for USB, PS/2 mouse, and PS/2 keyboard devices.
The location of these ports is shown in Figure 6 above. Note that, for this
board, the PS/2 mouse port is the upper PS/2 port, and the PS/2 keyboard port
is the lower PS/2 port.
The PS/2 connectors are probably quite familiar to you. The USB connectors,
however, may be foreign. The USB (Universal Serial Bus) is a versatile port.
This one port type can function as a serial, parallel, mouse, keyboard, or
joystick port. It is fast enough to support video transfer, and is capable of
supporting up to 127 daisy-chained peripheral devices. Close-ups of the USB
connector, as well as of the USB and PS/2 ports, are on the following page.

Installing your add-in cards is relatively simple but...
there are a few rules you need to follow when plugging in a card. In order to
assure proper operation and a quick installation, adhere to these guidelines:
•
•
•
•
If you are going to install a PCI-Bus interface card on your system,
be aware that any one of the two PCI slots can support a Master
or Slave device.
NEVER force a card into a slot. If it doesn’t fit, look at the socket
on the computer to make sure there are no wires or other
obstructions to the slot.
NEVER plug an ISA card into a PCI slot or a PCI card in an ISA
slot. You will void your warranty and damage your system board if
you do this.
When plugging the card in, especially when installing long cards,
try to push the entire card in at one time. Don’t force one end of
the card into the socket first and then the other. This will create a
rocking motion between the card and the slot and it will damage the
pins within the socket.
!
important!
•
Make sure that the cards are seated securely into the slots.

Chapter 2
Board Installation
•
Before turning on the system, make sure no cards are touching
each other or are shorting.
If you follow these basic guidelines, there shouldn’t be any problems with
installation. However, if you do encounter any problems, have a qualified
professional install your cards for you or contact your card manufacturer.
Remember, always read the manuals and installation notes that come with the
adapter cards. They contain important information which will help you install
the components right, the first time.
Next, you need to install your memory.
Since TYAN boards are manufactured with performance in mind, you should
use add-in components that match. Some DIMM modules may seem to be high
quality because of name or feel but that does not guarantee real-world
usability. Some cheaper or OEM memory may have brand-name components,
but they may be on inferior or substandard parts which do not meet the critical
tolerances our products require. Because of this, your memory may not work
correctly in a TYAN board though it may work well in a competitor’s board.
This is because many of our competitors do not adhere to the strict tolerances
required for high performance. If you buy a TYAN board, you are getting the
best system available. To make installation easy and trouble free, get high
quality parts. Some brands we recommend are Advantage Memory, Corsair
Microsystems, Millenium, Kingston Memory, QesTec Incorporated, Unigen,
Micron Technology, and Crucial Technology. These DIMMs have proven to
be very stable on our boards and perform extremely well.

Figure 9
To install your DIMMs, line your module up so that the pins fit into the slot.
There is only one way that your DIMM can fit properly. Make sure that the
short row of pins is lined up with the short gap in the DIMM slot. Figure 9
shows how to sit the DIMM into its slot. To insert the DIMM, push down
vertically on the module with even force, as shown in the photo. Do not shove
one end in first; doing so will bend the DIMM pins.
!
important!
To lock the DIMM into place, push the plastic clips on either end of the slot
onto the notches in the ends of the DIMM (see Figure 10 on the following
page). To remove your DIMM, simply pull the clips back, and pull up on the
module.

Finally, install your CPU.
Pentium II processors (233 through 450MHz) can be used on the Tiger 100.
Please refer to pages 29-30 for the correct CPU jumper settings for your board.
Remember:
!
important!
•
The CPU is a sensitive electronic component and it can easily be damaged
by static electricity. Do not touch the CPU pins with your fingers.
Before the CPU is installed, the motherboard 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.
Currently, Intel produces two types of Pentium II processors: the active (or
boxed) processor and the passive processor (see Figures 11 and 12 on the next
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 perfor-
mance, and both types can be installed in the Pentium II slot on the Tiger 100
board.

Installing CPU Retention Modules
Installation of a Pentium II processor requires a CPU retention module, which
is first secured onto the motherboard.
To attach the retention module, place the motherboard on a flat surface. 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

module sits flat against the
motherboard. Tighten the
screws in a clockwise manner
to secure the module to the
board. Warning: Do not

may damage the module and/or the motherboard.
Installing the Active Processor
When the retention module is securely installed, you are ready to plug in the
CPU. Press down firmly on the CPU until you hear a “click” (see Figure 15 ). This

clicking sound indicates that the CPU is fully locked into the retention module. If
you have an active processor, you will also need to connect the CPU’s cooling
fan cable to the cooling fan power connector on the board.
Figure 14
Figure 15
Locate the cooling fan connector (e.g. FAN1) on the motherboard. Plug the
CPU’s cooling fan cable into the cooling fan connector on the board. There will
be a plastic clip assembly similar to that of the ATX power connector that will
force you to connect the fan cable correctly (see Figure 16 below).

Installing the Passive Processor
The installation of the passive processor differs only slightly from that of the
active processor. Your passive CPU package should contain one CPU retention
module, one heat sink retention bracket with mounting locks, two mounting
attachments, and one heat sink lock.Install the retention module as explained in
the active processor section.
The heat sink mount (Figure 17)
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 the
pins and the holes in the
Figure 17
motherboard will determine the
correct orientation. When the bracket is correctly installed, the four pins on
top will be right next to the Pentium II CPU slot.
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.
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. Slowly press
down on the CPU module until the CPU locks into place. You will hear a
clicking noise when the CPU is locked securely into the module.
The heat sink lock (Figure 18) has four notches which will correspond to the
four pins on the heat sink mounting bracket. Gently slide the lock between the
heat sink and the heat sink mounting
bracket until both sides of the lock are
firmly secured. A 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.

(Figure 19) 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.
Removing the CPU.
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.

To remove the lock from the retention module, gently press the ends of the
locks inward and pull.
You are done.
Other than checking the jumper settings and cable connections and putting
the case back on, you are done. Installing a new motherboard may sound
difficult, but by following these directions, you should have a fairly uneventful
time installing our products. If you do encounter problems, your dealer will be
able to help you, or you can consult one of our many technical support
resources (see page 8).
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 inactive. Jumpers and pins are connected by
slipping the blue 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 drawings below for examples of “on” and
“off” pins and jumpers.

Soft Power Connector
FAN4
(Chassis)
The Soft Power Connector is located on pins 1 and 2 of jumper block J10. The
Tiger 100 uses the PIIX4e chip for power management, including turning on
and off the system. If the Power Button Function option in the Power
Mangement Menu is set to On/Off (which is the default), pressing the power
button once, after the BIOS has booted up, will turn the system on and off. If
the Power Button Function option is set to Suspend, pressing the power
button once will wake the system or send it in to Suspend mode. In this case,
you cannot turn the system off unless you shut down through the Windows
operating system or you hold the power button down for four seconds.
Speaker Connector Installation
The Tiger 100 provides a 4-pin header to connect the speaker. The speaker is
connected to pins 24-27 of jumper block J10.
Hardware Reset Switch Connector
Installation
The Reset switch on your case’s display panel provides you with the Hard-
ware Reset function, which is the same as power on/off. The system will do a
cold start after the Reset button is pushed. The Reset switch is a 2-pin
connector and should be installed on pins 22 and 23 of jumper block J10.

Chassis Intrusion Alarm Connector
The J8 connector is an intrusion alarm, that can be connected to the system
chassis. When active (J8 is closed), this alarm will alert the system administra-
tor anytime someone opens the system’s case.
Windows 95 Users:
You may encounter problems with some of the devices in the Intel 82371EB
chipset. Neither the PCI Bridge nor the PCI Universal Serial Bus device IDs for
this chipset (also called PIIX4e) are recognized by Windows 95. This is a soft-
ware problem, not a hardware problem, and can be easily remedied by either
upgrading to Windows 98 or by installing the Win-95 Patch found on the Tyan

CMOS RTC
The 440BX AGPset includes a Real Time Clock (RTC) circuit, which provides
the date and time for the system. If the external battery for the RTC is low, it will
prevent your system from POSTing, and you will not get a display. Normally
the life span of an external battery is 2 years. If yours is running low, you will
need to replace it with a new 3V lithium battery (Sony CR2032).
Flash EEPROM
The Tiger 100 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 Writer Utility (see
page 69).

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.
RAM Installation
The Tiger 100 uses a 64-bit data path from memory to CPU and can accommo-
date up to 1024MB of SDRAM. The 168-pin DIMMs must be of the 3.3V,
unbuffered variety. The position of the notch in the DRAM key position will
tell you whether or not a DIMM is unbuffered (see the figure below). All
installed memory will be automatically detected, so there is no need to set any
jumpers.

Cache Memory
Penitum II processors have the L2 (Level 2) cache built into their architecture,
so there is no need for an L2 cache on the motherboard. The Pentium II
processor has a physical L2 cache size of 512KB and a cacheable memory area
of 512MB. The Celeron CPU may have no onboard L2 cache or 128KB.

Frequently Asked Questions
Q: Why don’t I get a display after I put in my old DIMM module?
A: The 440BX 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 440BX’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.
EEPROM
Unbuffered
Buffered
RFU
168-pin DIMM
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 details.
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: Can I use EDO DIMMs on this motherboard?
A: No. The Intel 440BX AGPset does not support EDO memory. The 440BX
AGPset supports bus speeds of 100MHz, and EDO memory does not. You
must use SDRAM (which does support 100MHz bus speeds) on this board.
Q: What is AGP?
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 modes, which yield bandwidths of 264MB/s (at 33MHz
bus speed) and 533MB/s (at 66MHz bus speed), respectively. Compare this
with the mere 132MB/s (at 33MHz bus speed) that you get with the PCI bus.

Chapter 3
Onboard Resource Settings
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 details.
Q: Will my motherboard run a PII/Celeron/Mendicino CPU?
A:Yes, the BIOS version 1.07 supports Celeron 266-300MHz and the BIOS
version 1.12 supports the Celeron-A (Mendocino) 300-333MHz.
Q: Can I run dual Celeron/Mendocino CPU´s on this motherboard?
A: No, both Celeron and Mendocino CPU's are not designed to function in
dual CPU mode even on a dual slot motherboard.
Q: My system will not turn off - why?
A: The power button is designed to turn off the system ONLY when you
press/hold the power button for more than 5 seconds. BIOS version 1.12 will
provide an option for instant power-off .
Q: When I clear the BIOS with the jumper, it does not clear - why?
A: In most cases, BIOS can be cleared by inserting jumper JP3 to the 2-3
position. In some cases, certain brands of power supply need to be UN-
PLUGGED from a power source in order to clear the BIOS using jumper JP3.
Q: I´m getting a "motherboard resource conflict" - seen in Win95/98 Device
Manager as a yellow Exclamation Mark image. How do I clear it up?
A: More than likely, you have BIOS version 1.03. You need to install BIOS
version 1.07 to resolve this problem.
Q: My Wake-On LAN network burned out my power supply. What should I
do?
A: You need to use a power supply with 800ma at +5VSB power line. This is
because most Wake-On LAN network cards require +5V 750 mA in sleep mode.
We recommend our customer to purchase the ATX power supply with mini-
mum 800 mA at +5V SB output to avoid over-current damage to the power
supply.
Q: How can I disable the keyboard detection in the BIOS v.1.12?
A: You need to enable the Quick Boot option in CMOS - then the BIOS will not
check for a keyboard.

Type
Cylinders (Cyl)
Heads (Hd)
The number of cylinders in the disk drive.
The 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
Write Precompensation precompensation circuitry on the hard disk compensates for the physical
(WP)
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.
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.
Sectors (Sec)
Size
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).

Description
AMIBIOS tests all system memory.
AMIBIOS waits up to 40 seconds for a READY signal from the IDE hard disk drive. AMIBIOS waits for .5
seconds after sending a RESET signal to the IDE drive to allow the IDE drive time to get ready again.
AMIBIOS checks for a <Del> key press and runs AMIBIOS Setup if the key has been pressed.
Disabled
AMIBIOS does not test system memory above 1MB.
AMIBIOS does not wait up to 40 seconds for a READY signal from the IDE hard disk drive. If a READY signal
is not received immediately from the IDE drive, AMIBIOS does not configure that drive. AMIBIOS does not
wait for .5 seconds after sending a RESET signal to the IDE drive to allow the IDE drive time to get ready again.
You cannot run AMIBIOS Setup at system boot, because there is no delay for the Hit <Del> to run Setup
message.

Plug and Play Aware O/S
Set this option to Yes to inform AMIBIOS that the operating system can
handle plug and Play (PnP) devices. The settings are No or Yes.
PCI Latency Timer (PCI Clocks)
This option specifies the latency timings (in PCI clocks) for PCI devices
installed in the PCI expansion slots. The settings are 32, 64, 96, 128, 160, 192,
224, or 248.
PCI VGA Palette Snoop
When this option is set to Enabled, multiple VGA devices operating on
different buses can handle data from the CPU on each set of palette registers
on every video device. Bit 5 of the command register in the PCI device
configuration space is the VGA Palette Snoop bit (0 is disabled). For example, if
there are two VGA devices in the computer (one PCI and one ISA) and this
field is set for:
Setting
Description
Disabled Data read and written by the CPU is only directed to the PCI VGA device's palette registers.
Data read and written by the CPU is directed to the both the PCI VGA device's palette registers and
Enabled
the ISA VGA device palette registers, permitting the palette registers of both devices to be identical.
This option must be set to Enabled if any ISA adapter card installed in the
system requires VGA palette snooping.
Allocate IRQ to PCI VGA
Set this option to Yes to allocate an IRQ to the VGA device on the PCI bus.
The settings are Yes or No.
PCI IDE BusMaster
Set this option to Enabled to specify that the IDE controller on the PCI bus has
bus mastering capability. The settings are Disabled or Enabled.
OffBoardPCIIDECard
This option specifies whether or not an offboard PCI IDE controller adapter
card is used in the computer, and where it is installed. If an offboard PCI IDE
controller is used, the motherboard onboard IDE controller is automatically
disabled. The settings are Auto and Slot1 through Slot6. If Auto is selected,
AMIBIOS automatically determines the correct setting (including using the
onboard controller if no offboard controller card is detected). This option
forces IRQ 14 and 15 to a PCI slot on the PCI local bus. This is necessary to

OffBoard PCI IDE Primary IRQ
This option specifies the PCI interrupt used by the primary IDE channel on the
offboard PCI IDE controller. The settings are Disabled, Hardwired, INTA,
INTB, INTC, or INTD.
Offboard PCI IDE Secondary IRQ
This option specifies the PCI interrupt used by the secondary IDE channel on
the offboard PCI IDE controller. The settings are Disabled, Hardwired, INTA,
INTB, INTC, or INTD.
PCI Slot n IRQ Priority
These options specify the IRQ priority for PCI devices installed in the PCI
devices installed in the PCI expansion slots. The settings are Auto, IRQ 3, 4, 5,
7, 9, 10, and 11, in priority order.
DMA Channel n
These options allow you to specify the bus type used by each DMA channel.
The settings are PnP or ISA/EISA .
IRQn
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, you 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.
Reserved Memory Size
This option specifies the size of the memory area reserved for legacy ISA
adapter cards. The settings are Disabled, 16K, 32K, or 64K.

password, select the Supervisor Security option. You will be asked to enter the
current password. After you do so, you will be prompted to enter the new
password.
In either the Supervisor or User Security options, pressing <Enter> once when
asked for a new password, and a second time when asked to confirm the new
password, will uninstall the existing password. Note that uninstalling the
Supervisor password uninstalls the User password as well.
3.8 Language Utility
Currently, the BIOS Setup program is available only in English.
3.9 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 on the following page.
1. From the DOS prompt, 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, 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. You will be prompted to
press <F1> to run Setup. You may check your settings at this time, or simply
save and exit the program.

ACPI (Advanced Configuration and Power Interface) is a power management
specification that allows the operating system to control the amount of power
distributed to the computer’s devices. Devices not in use can be turned off,
reducing unnecessary power expenditure.
AGP (Accelerated Graphics Port) is a PCI-based interface which was designed
specifically for demands of 3D graphics applications. The 32-bit AGP channel
directly links the graphics controller to the main memory. While the channel
runs at only 66MHz, it supports data transmission during both the rising and
falling ends of the clock cycle, yielding an effective speed of 133MHz.
The AT was the original form factor of IBM’s PC.
ATAPI (AT Attachment Packet Interface), also known as IDE or ATA, is a drive
implementation that includes the disk controller on the device itself. It allows
CD-ROMs and tape drives to be configured as master or slave devices, just
like hard drives.
The ATX form factor was designed to replace the AT form factor. It improves
on the AT design by rotating the board ninety degrees, so that the IDE
connectors are closer to the drive bays, and the CPU is closer to the power

supply and cooling fan. The keyboard, mouse, serial, USB, and parallel ports
are built in.
Bandwidth refers to carrying capacity. The greater the bandwidth, the more
data the bus, phone line, or other electrical path, can carry. Greater bandwidth,
then, also results in greater speed.
A BBS (Bulletin Board System) is a computer system with a number of
modems hooked up to it which acts as a center for users to post messages and
access information.
The BIOS (Basic Input/Output System) program resides in the ROM chip, and
provides the basic instructions for controlling your computer’s hardware. Both
the operating system and application software use BIOS routines to ensure
compatibility.
A buffer is a portion of RAM which is used to temporarily store data, usually
from an application, though it is also used when printing, and in most key-
board drivers. The CPU can manipulate data in a buffer before copying it, all at
once, to a disk drive. While this improves system performance--reading to or
writing from a disk drive a single time is much faster than doing so repeatedly--
there is the possibility of losing your data should the system crash. Informa-
tion stored in a buffer is temporarily stored, not permanently saved.
A bus is a data pathway. The term is used especially to refer to the connection
between the processor and system memory, and between the processor and
PCI or ISA local buses.
Bus mastering allows peripheral devices and IDEs to access the system
memory without going through the CPU (similar to DMA channels).
A cache is a temporary storage area for data that will be needed often by an
application. Using a cache lowers data access times, since the needed informa-
tion is stored in the SRAM instead of in the slower DRAM. Note that the
cache is also much smaller than your regular memory: a typical cache size is
512KB, while you may have as much as 1GB of regular memory.
Cache size refers to the physical size of the cache onboard. This should not
be confused with the cacheable area, which is the total amount of memory
which can be scanned by the system in search of data to put into the cache. A
typical setup would be a cache size of 512KB, and a cacheable area of 512MB.

In this case, up to 512MB of the main memory onboard is capable of being
cached. However, only 512KB of this memory will be in the cache at any given
moment. Any main memory above 512MB could never be cached.
Closed and open jumpers Jumpers and jumper pins are active when they are
On or Closed, and inactive when they are Off or Open.
CMOS Complementary Metal-Oxide Semiconductors are chips that hold the
basic start-up information for the BIOS.
The COM port is another name for the serial port, which is so-called because it
transmits the eight bits of a byte of data along one wire, and receives data on
another single wire (that is, the data is transmitted in serial form, one bit after
another). Parallel ports transmit the bits of a byte on eight different wires at the
same time (that is, in parallel form, eight bits at the same time).
DIMM Dual In-line Memory Modules are a faster and more capacious form of
RAM than SIMMs, and do not need to be installed in pairs.
DIMM bank DIMM banks are sometimes called DIMM sockets, because the
physical slot and the logical unit are the same. That is, one DIMM module fits
into one DIMM socket, which is capable of acting as a memory bank.
DMA Direct Memory Access channels are similar to IRQs. DMA channels allow
hardware devices (like sound cards or keyboards) to access the main memory
without involving the CPU. This frees up CPU resources for other tasks. As
with IRQs, it is vital that you do not double up devices on a single line. Plug
and Play devices will take care of this for you.
In Doze mode, only the CPU’s speed is slowed.
DRAM Dynamic RAM is a widely available, very affordable form of RAM
which has the unfortunate tendency to lose data if it is not recharged regularly
(every few milliseconds). This refresh requirement makes DRAM slower three
to ten times slower than non-recharged RAM such as SRAM.
EDO RAM (Extended Data-Out RAM) speeds access to memory locations by
assuming that memory addresses are static: the next time it looks for a bit of
data, it will be at the same spot, or one nearby.

keep up with changes in the BIOS programs without having to buy a new chip.
ESCD (Extended System Configuration Data) is a format for storing informa-
tion about Plug and Play devices in the system BIOS. This information helps
properly configure the system each time it boots.
Firmware is low level software that controls the system hardware.
Form factor is an industry term for the size, shape, power supply type, and
external connector type of the PCB (personal computer board) or motherboard.
The standard form factors are the AT and ATX, although TYAN also makes
some Baby-AT boards.
A Global timer is an onboard hardware timer, such as the Real Time Clock.
Handshaking is a form of encryption. One system, typically the server, sends
an encryption scheme to another agent, typically a client. Thus, the client’s
data is protected during transmittal to the server.
HDD stands for Hard Disk Drive.
H-SYNC controls the horizontal properties of the monitor.
IC (Integrated Circuit) is the formal name for the computer chip.
IDE Integrated Device (or Drive) Electronics is a simple, self-contained hard
drive interface. It can handle drives up to 8.4GB in size. Almost all IDEs sold
now are in fact Enhanced IDEs (EIDEs).
IDE INT (IDE Interrupt) is a hardware interrupt signal that goes to the IDE.
I/O Input/Output is the connection between your computer and another piece
of hardware (mouse, keyboard, etc.).
IRQ An Interrupt Request is an electronic request that runs from a hardware
device to the CPU. The interrupt controller assigns priorities to incoming
requests and delivers them to the CPU. It is important that there is only one
device hooked up to each IRQ line; doubling up devices on IRQ lines can lock
up your system. Happily, Plug and Play operating systems take care of these

ISA stands for Industry Standard Architecture. ISA is a slower 8- or 16-bit BUS

Latency is the amount of time that one part of a system spends waiting for
another part to catch up. This is most common when the system sends data
out to a peripheral device, and is waiting for the peripheral to send some data
back (peripherals tend to be slower than onboard system components).
NVRAM ROM and EEPROM are both examples of Non-Volatile RAM, memory
that holds its data without power. DRAM, in contrast, is volatile.
OEMs (Original Equipment Manufacturers) like Compaq or IBM package other
companies’ motherboards and hardware inside their case and sell them.
The parallel port transmits the bits of a byte on eight different wires at the
same time (that is, in parallel form, eight bits at the same time).
PCI stands for Peripheral Component Interconnect. PCI is a 32-bit local bus
(data pathway) which is faster than the ISA bus. Local buses are those which
operate within a single system (as opposed to a network bus, which connects
multiple systems).
The PCI PIO (PCI Programmable Input/Output) modes are the data transfer
modes used by IDE drives. These modes use the CPU for data transfer (DMA
channels do not). PCI refers to the type of bus used by these modes to
communicate with the CPU.
PCI-to-PCI bridge allows you to connect multiple PCI devices onto one PCI
slot.
Pipeline burst SRAM is a fast secondary cache. It is used as a secondary
cache because SRAM is slower than SDRAM, but usually larger. Data is
cached first to the faster primary cache, and then, when the primary cache is
full, to the slower secondary cache.
Pipelining improves system performance by allowing the CPU to begin
executing a second instruction before the first is completed. A pipeline can be
likened to an assembly line, with a given part of the pipeline repeatedly
executing a set part of an operation on a series of instructions.

PM timers (Power Management timers) are software timers that count down
the number of seconds or minutes until the system times out and enters sleep,
suspend, or doze mode.
PnP is an acronym for Plug and Play, a design standard that has become
ascendant in the industry. Plug and Play devices require little set-up to use.
Novice end users can simply plug them into a computer that is running on a
Plug and Play-aware operating system (such as Windows 95), and go to work.
Devices and operating systems that are not Plug and Play require you to
reconfigure your system each time you add or change any part of your
hardware.
The term RAM (Random Access Memory), while technically referring to a type
of memory where any byte can be accessed without touching the adjacent
data, is often used to refer to the system’s main memory. This memory is
available to any program running on the computer.
ROM (Read-Only Memory) is a storage chip which contains the BIOS (Basic
Input/Output System), the basic instructions required to boot the computer
and start up the operating system.
SDRAM (Synchronous Dynamic RAM) is so-called because it can keep two
sets of memory addresses open simultaneously. By transferring data alter-
nately from one set of addresses, and then the other, SDRAM cuts down on
the delays associated with non-synchronous RAM, which must close one
address bank before opening the next.
The serial port is so called because it transmits the eight bits of a byte of data
along one wire, and receives data on another single wire (that is, the data is
transmitted in serial form, one bit after another).
SIMM Single In-line Memory Modules are the most common form of RAM.
They must be installed in pairs, and do not have the carrying capacity or the
speed of DIMMs.
SIMM bank/socket SIMM sockets are the physical slots into which you stick
SIMM modules. A pair of SIMM sockets form a SIMM bank, and act as a unit.
If only one socket is filled, the bank will not operate.
In Sleep/Suspend mode, all devices except the CPU shut down.

Glossary
SRAM Static RAM, unlike DRAM, does not need to be refreshed in order to
prevent data loss. Thus, it is faster, and more expensive.
In Standby mode, the video and fixed disk drive shut down; all other devices
operate normally.
UltraDMA/33 is a fast version of the old DMA channel. UltraDMA is also
called UltraATA. Without UltraDMA your system cannot take advantage of
the higher data transmission rates of the new UltraATA hard drives.
Universal Serial Bus or USB, is a versatile port. This one port type can
function as a serial, parallel, mouse, keyboard, or joystick port. It is fast
enough to support video transfer, and is capable of supporting up to 127
daisy-chained peripheral devices.
VGA (Video Graphics Array) is the PC video display standard.
V-SYNC controls the vertical properties of the monitor.
ZIF socket Zero Insertion Force sockets make it possible to insert CPUs
without damaging the sensitive pins. The CPU is lightly placed in an open ZIF
socket, and the metal lever pulled down. This shifts the processor over and
down, guiding it into place on the board.
