1.4 Technical Support
If a problem arises with your system , you should turn to your dealer for he lp first. Your system has most
likely been configure d by t hem, a nd the y should have the best ide a of wh at har dware and so ftwa re your
system contains. Hence, they shou ld be of the mo st assist anc e. F urt her more, if you p urch ase d you r system from a dealer near you, you can actual ly bring your system t o them to have it service d, instead of
attempting to do so yourself (which can have expensive consequences).
Help Resources:
1. See the FAQ and beep codes section of this manual.
2. See the Tyan website for FAQ, bulletins, driver updates, and other
information: http://www.tyan.com
3. Contact your dealer for help BEFORE calling Tyan.

Chapter 2: Board Installation
2.1 Unpacking
The retail motherboard package should contain the following:
Thunder i860 motherboard
Memory Expansion Card (MEC)
(2) Continuity RIMMs
34-pin floppy cable
UltraDMA-100/66/33 IDE cable
68-pin Ultra160 LVD SCSI cable

Thunder i860 user’s manual
Tyan driver CD
(2) LSI SYM1010 SCSI Driver Disks
2.2 Installation
You are now ready to install your motherboard. T he mounting hole pattern of the mo therboard ma tches
the ATX board specifications, so your chassis must b e capable of supporting an Extend ed ATX board
(check the motherboard dimensions provided on p. 6).
2.3 How to install our products right.. the first time.
Question: what’s the first thing I should do?
The first thing you should do is read the user’s manual. It contains important information which will m ake
configuration and setup much easier, as well as provide information on device installation and component
set up. By reading through the manual completely befo re installing your motherboard, you will have a
complete overview on the installation.
* if you require a different I/O shield solution, please contact your chassis vendor

Here are some safety tips:
(1) Ground yourself properly before removing your motherboard from the antistatic bag. Unplug
the power from your computer power supply and touch any metal part on the computer case. (You
might also want to 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.
Having reviewed the precautions above, the next step is to take the motherboard out of the cardboard box
and static bag, hold it by its edges, and pl ace it on a grounded a ntistatic surface, com ponent side up.
Inspect the board for damage.
NOTE: DO NOT APPLY POWER T O THE BOARD IF IT HAS BEEN DAMAGED!
Press down on any of the socketed ICs if it appears that they are not properly seated (the board should
still be on an antistatic 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, unlike physical damage, causes the device to fail over time.

2.4 Quick References for Jumpers
In this manual, the term “close d” and “on” are used wh en referring to jumpers (or jumper pins) that are
active; “open” and “off” a re u s ed whe n re fer ring to j u mp ers (or j um per pin s) that are inactive. See Figure
2.0a and Figure 2.0c for examples of “on” and “off” pins and jumpers.
Jumpers and pins are connec ted by slipping the plastic jum per connector over the top of tw o adjacent
jumper pins (indica ted b y 1-2 or 2-3 ). Th e met al r od insid e the plast ic shell bridg es the gap b etween the
two pins, completing the circ uit. See Figure 2.0b and Figure 2.0d for more examples of 3-pin jumper
connections. NOTE: The small number “1” indicates pin 1.
The tables and maps on the following pages will help you set the jumpers for CPU speed, infrared, and
external connector pin assignments, among others. The miniature motherboard maps will help you locate
the jumpers on your board. Full page maps of the motherboard can be found on the next two pages.

J. Soft Power Connector
The soft power connector is part of jumper block J24 (pins 6 and 8). This board uses the chipset for power
management, including tur ning on and off the system. If the power b utton function option in the BIOS
Power Management me nu is set to “On/Off” (wh ich is the d efault), pr essing the p ower button once after
the BIOS has booted up will turn the system on a nd off. If the power button functio n is set to Suspend,
pressing the power button once will wake up t he system or send it to Suspend mode. In this case, you
cannot turn the system off unless yo u shut d own through the Windo ws oper ating system o r you ho ld the
power button down for four seconds (BIOS-dependent feature).
K. Hardware Reset Switch Connector Installation
The reset switch on your chassis case provides you with the Hardware Reset function, which is the same
as power on/off, except that the system will immediately execute a cold start afte r the reset button is
pushed. The reset switch needs to be connected to jumper block J24 (pins 5 and 7).

2.7 Mounting the Motherboard into the Chassis
Your chassis may include mounting hardware. If mounting hardware w as included, yo u can use the fo llowing examples to help you in installing your motherboard into the chassis.
The chassis may have com e wit h th e stud s int egr ate d in to t he cha ssis wa ll, so in t hose ca ses you wou ld
only need to use scre ws (p ossibly i nclude d with you r chass is) to instal l the m other board . See the ex amples (Figure 2.0, shown below) for more details.
If the chassis includes mounting hardware without the studs pre-installed, then you will need to install the
motherboard using the mounting hardware as shown in t he examples below. Remember not to overtighten any of the sc rews, or you might risk breaking i nternal tr aces in the su rroundi ng area, or damage
the motherboard in some other way.
Other examples of how to install your motherboard using other hardware (that may or may not have been
included with your chassis) are shown below.

2.8 Installing Memory
Please keep in mind that although some memory modules may appear to be high-quality, they may contain inferior or substandard parts. The type of memory you choose to install should be checked against
the memory compatibility list, which is available from Tyan’s website at http://www.tyan.com
Memory Installation Procedure
Step
Step
Step
Line up your module so that the pins fit in to the slot. There is only one way your memory
1
module can fit properly. Make sure that the short row of pins is line d up with the short gap in
the RDRAM socket. See Figure 2.1 (on p.17) for graphic det ai ls on how the memor y sh ou ld
be installed.
Insert the memo ry module by pushin g it into t he socket w ith even force. Do not insert one
2
end and then the other: inst all the wh ole modul e at once or you m ight damag e the mem ory
module and/or the socket.
Lock the memory into place by pus hing the clips back on either en d of the socket onto the
3
notches in the ends of the memory module, as shown below.
1 2
Memory Uninstallation Procedure
Removing the RIMM is just the reverse: simply pull back the clips from the memory module (as shown
below), and carefully pull the module straight out. Place the memory modules in an anti-static bag as
soon as you remove them to avoid static damage.
18
NOTE:
21
Also take care that you do not cause yourself injury if you are removing the
memory modules after using the motherboard, since the module(s) may be hot.
http://www.tyan.com
Page 19
Here are some details of memory installation for this board:
Inner and outer RIMM sockets must be matching (e.g. if you have one RIMM module in the inner
socket, another RIMM module must be installed in the other inner socket, and so on).
See p. 20 and Figure 2.1 (below) for an example.
Inner Modules
Outer Module Outer Module
are matching
Figure 2.1
Any empty slots must be filled with C-RIMM Continuity modules. Tyan has included (2) C-RIMM
modules for your convenience (examples** are shown above in Figure 2.1).
This motherboard supports up to 2GB* PC800 ECC Registered RDRAM. Check the Tyan memory compatibility section of the website for more details: http://www.tyan.com
* not verified at time of print, check the Tyan website for updates: http://www.tyan.com
** note: the examples may not necessarily represent the actual C-RIMMs included with the board.

Memory Configuration Examples
Figure 2.2 and the table below should be used in conjunction to determine possible memory configura-
tions. Not all possible configurations are listed. (NOTE: C-RIMM means Continuity RIMM)
NOTE: The Rambus memory modules must be installed in a top-to-bottom fashion (e.g. fill in socket 1,
then socket 2, and match the memory quantity in socket 3 with socket 1’s memory quantity, and then
match the memory quantity in socket 4 with socket 2’s memory quantity, and so on).

2.9 Installing the CPU and Cooling Fan
Intel Xeon processors ONLY (1.7* GHz and above*) can be used on the Thunder i860. For more information on CPU compatibility, check Tyan’ s website: http://www.tyan.com.
Remember the following: 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. You should be able to insert the CPU into
the socket with virtually no force. Do not press down hard on the CPU as you might bend or break the
pins.

Installing the Intel Xeon CPU
Before installing the CPU, check it for damaged. Make sure that none of the pins are bent. There is only
one way to install the CPU. There are two beveled corners in the socket face (shown in the image above)
that match two beveled corners in the CPU pin set. Be very sure that the pins on the CPU match the
socket face pins.
Step
Step
Carefully lift the arm of the ZIF socket until it is at a 90-degree angle

pointing away from the motherboard. be very careful not to damage
any components that might be next to the CPU socket. Please note
that each picture for this section (see right) corresponds to the
step.
There are two beveled corners on the CPU pin group, which will
2
match the two an gled corners on the socket face. Carefully install
the CPU by lining both Pin 1 on the CPU and Pin 1 o n the socket
(see right), making sure the pins actually fit into the socket face. Do
not force the CPU into the socke t if it does not fit: check the pin
alignment of CPU pins to socket holes.

Installing the Cooling Fan(s)
After a CPU has been installed, you will need to install the prop er cooling d evice for the CPU. This
device, a heatsink/fan com bination , can be purc hased at ma ny compute r retail store s. Installat ion of the
cooling device may vary depe nding on the fan manufacturer ’s design. You should also take space into
consideration when in stall a c ooli n g d evice : m ake su re th e cooling device is not too big, or el se y ou ma y
end up damaging components around the CPU socket.
Tyan highly recommends t hat you use some type of
thermal compound (avai lable from many co mput er ret ail
stores), between the CP U and heat sink, to maximize
distribution of heat away from the CPU. Please use extra
caution when installing any type of clamp-style fan, or
else damage may occur to the CPU socket, and/or the
CPU itself. See the picture to the right for an exa mple
of how to connect the cooling fan’s power supply.
Another diagram has also been provided below, to aid in
CPU fan installation onto the socket. Check with your
cooling device vendor for more details about installation.
Please note that Xeon CPUs require a different cooling device than
that of other socketed CPUs. Check with your vendor for details on
cooling options.

2.10 Connecting IDE and Floppy Drives
A variety of IDE a nd ATAPI-compliant devices can be i nstalled on this m otherboard, su ch as hard disk
drives (HDDs) and CD-ROMs.
Please keep in mind that on this mothe rboard, the primary IDE connec tor is BLACK, and the secondary IDE
connector is WHITE. See the picture to the rightfor an
example of the IDE cable properly connected to the
motherboard, with the BLUE end of the IDE cable
installed on the motherboard .
Pin 1 on the IDE cable is usually denoted by a red or colored stripe down o ne side of the cable. That side o f the
cable must match Pin 1 on the motherboard’s IDE connector. There will also be a key pin on the cable that
matches with a notch in the ID E connector, to ensure
proper installation. Consult the documentation that came
with your IDE/ATAPI device, or contact the device’s
manufacturer for more details on installation.
Please note that UltraDMA-100/66 IDE HDDs require a
special 80-wire cable which has additional grounding
wires. This cable has been incl uded with this motherboard for your convenience. The UltraDMA-100/66
cable is backwards compatible with UltraDMA-33 and
legacy IDE HDDs.

2.11 Installing Add-on Cards
There are a few rules you need to follow when installing add-on cards. In order to assure proper operation
and a quick installation, adhere to the following guidelines:
If you are going to install a PCI-bus interface card on your system, be aware that any one of the
five 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 motherboard to make
sure there are no wires or other obstructions to the slot.
NEVER plug an ISA card into a PCI 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, or a rocking
motion between the card and the slot might occur, and could damage the pins within the socket.
Make sure the cards are seated securely into their slots.
Before turning on the system, make sure no cards are touching.
Check the PCI device specifications with the PCI slot specifications (p.5) BEFORE installing!
When installing the add-on cards, make sure the cards are installed with even force; do not insert one
end and then the other. See the before (Figure 2.1a) and after (Figure 2.1b) example in sta l la t ion i ma g es
below for details.

About the AGP Pro slot
If you are planning to install an AGP Pro, Pro 50, or 4X AGP Pro 50-compliant card, a small plastic retention piece must be removed from the AGP Pro slot before the card can be installed.
1 2
Figure 2.2a Figure 2.2b
First, make sure the card you’re installing is an AGP Pro-compliant card. Next, locate the small plastic
retention piece in the AGP Pro slot (Figure 2.2a, above), and use a tool with a small hard tip (such as a
pen) to remove the retention piece (Figure 2.2b, above). Tyan recommends you save this piece for
future use (e.g. in case a regular AGP card is installed later on).
T o further ensure that the AGP card will not rock back and forth, make sure that the metal endpiece of the
AGP card is flush with the motherboard edge.
Only remove the small plastic retention piece if you are going to install an AGP
Pro-compliant card. Installing a regular AGP card without the retention piece can
cause the card to rock back and forth, possibly dam ag ing the card and /or moth er-

2.14 Frequently Asked Questions (FAQ)
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 conflicts related to the IRQ, or DMA. If
you are using Microsoft Windows, the Control Panel is a good place to start investigating the conflict.
Please consult your operating system documentation for details. Secondly, slowing down the memory timing in the BIOS’ chipset setup section might help the situation as well. Many memory modules are not
suitable for high performance systems and might be the main source of your problem. Also check to make
sure you are using a dualXeon-capable, APPROVED* or better power supply. Lastly, make sure the
motherboard is receiving adequete cooling.
Q: I have a question about memory compatibility; what memory will work on my motherboard?
A: Memory compatibility information can be found on Tyan’s website at: http://www.tyan.com
Q: Where can I get additional accessories for my Tyan motherboard?**
A: You can purchase additional Tyan-approved accessories** at the Tyan Computer Online Store:

Chapter 3: BIOS Setup
Introduction to the BIOS setup
The BIOS is the basic inpu t/output syst em, requ ired by the computer to perform functions suc h as CPU
and hard drive supp ort . T his ch apt er des cri be s differe nt settings for the BIOS t hat can be use d to co nfigure your system.
The BIOS section of the manual is subject to change without notice and is provided here for reference purposes o nly. The settings an d conf iguration s of the BIOS are current at the t ime of pr int,
and therefore they may not be exactly the same as that displayed on your screen.
This manual describes the BIOS setup prog ram. The setup pro gram lets y ou modify b asic conf iguration
settings. The settings are the n sto red in a de dicated battery-backed memo ry, called NVRAM, that re tai n s
the information when the power is turned off.
The BIOS in your motherboard is a customized version of an industry-standard BIOS for IBM PC AT-compatible personal comput ers. It supports Intel x86 and compatible processo rs. The BIOS provides cri tical
low-level support for the system central processing, memory, and I/O subsystems.
The BIOS has been customized by add ing i m por tan t, but non- stan da rd, featu re s such as vir us and password protection, power management, a nd detailed fine- tuning of the ch ipset controlling the s ystem. The
rest of this manual is intende d to guide you through the process of configuring y our system using this
BIOS setup program.
Starting Setup
The BIOS is immediately a cti vat ed wh en yo u fi rs t tur n on the co mp ute r. The BIOS reads s ystem con figuration information in CM OS RAM and be gins the pro cess of checking out the system and configur ing it
through the Power-On Self Test (POST).
When these preliminaries are finishe d, the B IOS seeks a n operat ing system on one of t he data storage
devices (HDD, floppy drive, etc.) If one is found, the BIOS will launch that operatin g system and hand
control of system operations to it. You can start the setup program by pressing the [F2] key while the system is booting up.

Note: If you experience problems with setting up your system, always check the following things in the
following order:
MEMORY, VIDEO, CPU
By checking these items, you will most likely find out what the problem might have been when setting up
your system. For more information on troubleshooting, check the Tyan website at http://www.tyan.com
4.1 Beep Codes
Fatal errors, which halt the boot process, are communicated through a series or audible beeps. For example, if the Phoenix BIOS POST can initialize the video but an error occurs, an error message will be displayed. If it cannot display video, it will convey a series of beeps.
If you hear one long beep followed by two short beeps, then a video problem has probably occured and
the BIOS is having difficulty initializing the video display. Any other beep sequences that may or may not
occur are probably due to memory problems.

Appendix I: SCSI Installation* and LAN Information
Introduction
With the dual channel onboard Ultra160 LVD SCSI option*, you can connect up to 30 SCSI peripherals
such as hard drives, CD-ROMs, and tape drives. Please note that this guide only provides basic instructions on connecting SCSI devices to your motherboard. For more detailed SCSI installation instructions,
refer to your SCSI device documentation or to LSI Logic’s website: http://www.lsilogic.com

(bootrom) s upport
SPI-3 Parallel Protoc ol Request (PPR)
Basic Domain Validation
Legacy support fo r no n- U ltr a1 60 SC S I devices
The LVD signaling used for Ultra160 devices operates differently than single-ended signaling used on
Ultra, Fast, and Fast Wide SCSI devices. Ultra160 LVD SCSI devices are designed with multi-mode capability so that if a single-ended device is connected to the Ultra160 LVD SCSI bus, the Ultra160 devices
automatically switch to single-ended mode. When an Ultra160 LVD SCSI device operates in single-ended
mode it is subject to the cable distance limitations and signal noise problems of that interface. LSI recommends that single-ended Ultra and earlier devices be kept on a separate channel than the Ultra160 LVD
SCSI devices. This will permit the Ultra160 devices to operate at full speed and cable distances.
Setting up internal SCSI peripherals
Its very important that SCSI peripherals be set up before installing them to the SCSI connector. The setup
for SCSI peripherals usually involves setting SCSI IDs, checking for termination, mounting the peripherals
inside the chassis, and then hooking up power to each peripheral. Since setup can vary from peripheral to
peripheral, always refer to the peripherals documentation for specific instructions. Below are some guidelines for s etting SCSI IDs and termination on your peripherals.
Checking SCSI IDs
Both the motherboard SCSI connectors and each peripheral you connect need to have a unique ID, ranging from 0 t o 15. IDs do not have to be sequential, as long as each connector and each peri pheral has a
different number for each channel. Each SCSI channel on the motherboard is preset to SCSI ID and
should not be changed. If you will be booting from a SCSI HDD, its best to set the disk’s ID at 0 or 1. Most
SCSI HDDs come from the factory preset to ID 0. The IDs for internal peripherals are usually set with
jumpers; external peripherals are usually set with a switch on the back of the peripheral. Check your
peripheral’s documentation for more details.
Terminating SCSI devices
T o ensure reliable communication on the SCSI bus, the peripheral on the end of each cable, or the end of
the cable itself, must have a terminator installed (or enabled). The peripherals between the ends of each
cable must have the terminator removed (or disabled). Check your peripheral’s documentation for more
details.
Connecting SCSI peripherals
A total of 30 SCSI peripherals can be connector to the onboard SCSI connectors (15 devices per channel/
connector). Before connecting peripherals, be sure to also review Setting up internal SCSI peripherals
above.
Connecting internal cables for Ultra160 LVD SCSI devices
When connecting internal Ultra160 LVD peripherals there are special SCSI cables necessary to sustain
the higher speeds of LVD signaling. If your cables are not marked, you can identify most Ultra160 LVD
SCSI cables as having twisted pairs of the flat ribbon cable in between the device connectors. These
cables will usually have a terminator built into the end of the cable.

Information on the LSI Symbios 53C1010 SCSI BIOS
The SCSI BIOS is the bootable ROM code that manages SCSI hardware resources. It is also specific to
the family of Symbios SCSI controllers or processors. By integrating with the standard system BIOS, the
Symbios SCSI BIOS extends the standard disk service routine through INT13h.
During boot time initialization, the SCSI BIOS will determine if there are other hard disks, such as an IDE
drive, that are already installed by the system BIOS. If there are, the SCSI BIOS will map any detected
SCSI drives behind the drive(s) already installed. Otherwise, the SCSI BIOS will install drives starting
with the system boot drive. In this case, the system boots from a drive controlled by the SCSI BIOS. For
4.05 versions and higher, LSI Log ic supports the BIOS Boot Specification (BBS).
Boot Initialization with BIOS Boot Specification (BBS)
The Symbios SCSI BIOS provides support for the BIOS Boot Specification (BBS), which allows you to
choose which device to boot from by selecting the priority.
In the system BIOS setup, the Boot Connection Devices menu appears with a list of available boot
options. Use that menu to select the device and rearrange the order. Then exit to continue the boot process.
CD-ROM Boot Initialization
The SCSI BIOS supports boot initialization from a CD-ROM drive.
The five types of emulation are:
No emulation disk
Floppy 1.2MB emulation disk
Floppy 1.44MB emulation disk
Floppy 2.88MB emulation disk
Hard Disk Emulation
The type of emulation assigns the drive letter for the CD-ROM. For example, if a 1.44MB Floppy emulation CD was loaded, then the CD-ROM drive would become the designated A: drive, and the existing
floppy (if any) would become drive B:.
Starting the SCSI BIOS Configuration Utility
This motherboard comes with the SCSI BIOS version 4.xx, and it includes the Symbios SCSI BIOS Configuration Utility so that you can change the default configuration of your SCSI host adapters. You may
need to change the default configuration due to conflicts between device settings or if you are looking to
optimize system performance.
If you have the LSI SCSI BIOS enabled (see p. 33), the following message will appear on your screen
after the system BIOS boots:
Press CTRL-C to start Symbios Configuration Utility...
This message remains on your screen for about 5 seconds, giving you a short amount of time to start the
utility. When you press [CTRL-C] to start the utility, the system will pause while it loads the utility, then the
main menu for the utility will appear.

Field Details on field
<Device Properties>
SCSI Parity
Host SCSI ID
SCSI Bus Scan Order
Removeable Media Support
To view and modify device properties, press
[ENTER].
This field indicates whether SCSI parity is enabled
for an adapter. When disabled, it is also necessary
to disable disconnects for all devices, as parity
checking for the reselection phase is NOT disabled.
If a non-parity generating device disconnects, its
operation will never complete because the reselection fails due to parity error.
This field indicates the SCSI identifier of an adapter
[0-7] or [0-15]. It is recommended that this field be
set to the highest priority SCSI identifier, which is 7.
This field indicates the order in which to scan SCSI
identifiers on an adapter. Changing this item will
affect drive letter assignment(s) if more than one
device is attached to an adapter. Note: Changing
this item may conflict with an operating system
that automatically assigns drive order.
This field specifies the removable media support
option for an adapter. Three settings are allowed:
None indicates no removable media support
whether the drive is selected as first (BBS), or is first
in the scan order (non-BBS).
Boot Drive Only provides removable media support
for a removable harddrive if it is first in the scan
order.
With Media Installed provides removable media
regardless of the drive ordering.
This field defines how the Cylinder Head Sector values are mapped onto a disk without pre-existing partition information. CHS Mapping allows two settings:
SCSI Plug-and-Play Mapping (default value), and
Alternate CHS Mapping.
SCSI Plug-and-Play Mapping automatically determines the most efficient and compatible mapping.

bly less efficient mapping that may be required if a
device is moved between adapters fro m differen t
vendors.
Note: Neither of these options has any effect after a
disk has been partitioned using FDISK*. To change
the CHS Mapping on a partitioned disk, use FDISK*
to delete all partitions. Then reboot the system to
clear memory or the old partitioning data will be
reused, thus nullifying the previous operation.

Termination Control
This field indicates the number of seconds to wait
between spinups of devices attached to an adapter.
Staggered spinups will balance the total electrical
current load on the system during boot. The default
value is 2 seconds with choices between 1 and 10
seconds.
This fiel d indicates whether an adapter has one or
more devices attached that are shared with one or
more other adapters and therefore, the Symbios PCI
SCSI BIOS should avoid SCSI Bus resets as much
as possible.
This option allows the user to enable an adapter to
join a cluster of adapters without doing any SCSI
bus resets. This is a requirement for Microsoft Cluster Server. The default value is No with an alternate
option of Yes.
This fiel d indicates whether an adapter has automatic termination control, and if so, its current status.
Two settings are:
Auto:
The adapter automatically determines
whether it should enable or disable its termination.
Off:
Termination at the adapter is off, the
devices at the ends of the SCSI bus must
terminate the bus.

Device Properties
The Device Properties screen provides viewing and updating individual device settings for an adapter.
Changing a setting for the host device (for example, SCSI ID 7) changes the setting for all devices. Below
are the fields available along with their descriptions.
Field Details on field
SCSI ID This field indicates the device’s SCSI identifier.
Device Identifier
Sync Rate
Scan ID
Scan LUNs > 0
This field indicates the ASCII device identitifer string
extracted from the device’s Inquiry Data.
This field indicates the maximum synchronous data
transfer rate, in Mega Transfer per second.
Mega Transfers/sec
0=Async 0=Async50=Async 0=Async
This field indicates the maximum data width in bits.Data Width
This field indicates whether to scan for this SCSI
identifer at boot time. This item can be used to
ignore a device and to decrease boot time by disabling the inquiry of unused SCSI identifiers.
Set this option to “No” if there is a device that you do
not want to be available to the system. Also, on a
bus with only a few devices attached, the user can
speed up boot time by changing this setting to “No”
for all unused SCSI IDs.
This field indicates whether to scan for Logical Unit
Numbers (LUNs) greater than 0 for a device. LUN 0
is always queried. This option should be used if a
multi-LUN device responds to unoccupied LUNs or if
it is desired to reduce the visibility of a multi-LUN
device to LUN zero only.
Set this option to “No” if you have problems with a
device that responds to all LUNs whether they are
occupied or not. Also, if a SCSI device with multiple
LUNs exists on your system but you do not want all
of those LUNs to be available to the system, then set
this option to “No”. This will limit the scan to LUN 0
only.

newer) devices run faster with disconnect enabled,
while some (mostly older) devices run faster with
disconnect disabled.

Device Properties (continued)
Field Details on field
SCSI Timeout
Queue Tags
Boot Choice
Format
This field indicates the maximum amount of time [0
to 9999] in seconds to wait for a SCSI operation to
complete.
Since timeouts provide a safeguard that allows the
system to recover should an operation fail, it is recommended that a value greater than 0 be used. A
value of 0 allows unlimited time for an operation to
complete and could result int he system hanging
(waiting forever) should an operation fail.
Press [ENTER], type in a value, and then press
[ENTER] again to specify a new timeout value.
This field indicates whether to allow the use of
queue tags for a device. Currently the BIOS does
not use queue tags. This item specifies queue tag
control to higher level device driver s.
This field indicates whether this device may possibly
be selected as the boot device. This option is only
applicable to devices attached to adapter number 0
(in the boot list) on non-BBS systems. It provides
primitive BBS flexibility to non-BBS systems.
Select this option to low-level format the device.
If enabled, this option allows low-level formatting on
a disk drive. Low-level formatting will completely and
irreversibly erase all data on the drive.
Note: Formatting will default the drive to a 512-byte
sector size even if the drive had previously been formatted to another sector size.
Select this option to verify all sectors on the device

Appendix II: Glossary
ACPI (Advanced Configuration an d Power Interface): a pow er m anage ment s pecific ation th at al lows 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 (A
ccelerated Graphics Port): a PCI-base d inte rfa ce whic h was de sign ed spe ci fical ly for dem and s of
3D graphics applications. Th e 32-bi t AGP chann el directl y links the grap hics con troller to the main memory. While the channel runs at only 66 MHz, it supports data transmission during both the rising and falling
ends of the clock cycle, yielding an effective speed of 133 MHz.
ATAPI (AT
the disk controller on the dev ice itsel f. It all ows CD -ROMs an d tape dr ives to be co nfigure d as maste r or
slave devices, just like HDDs.
ATX: the form factor designed to replace the AT form factor. It improves on the AT design by rotating the
board 90 degrees, so tha t the IDE connecto rs are close r to the drive b ays, and the CPU is closer to the
power supply and cooling fan. The keyboard, mouse, USB, serial, and parallel ports are built-in.
Bandwidth: refers to carrying cap aci ty. The greater the ban dw idt h, th e m ore dat a the bus, phone line, or
other electrical path, can carry. Greater bandwidth, then, also results in greater speed.
BBS (B
of all Initial Program Lo ad (IPL) devices, and then stores that list in NV memory. IPL devices have the
ability to load and execute an OS, as we ll as provide th e ability to return to t he BIOS if the OS loa d process fails for some reason. At that point the next IPL device is called upon to attempt loading of the OS.
BIOS (B
instructions for controlling your computer’s hardware. Both the operating system and application software
use BIOS routines to ensure compatibility.
Buffer: a portion of RAM which is u sed to te mp ora ril y sto re d ata , usu all y fr om an a pplic a tion , tho ugh i t is
also used when printing, and in most keyboard dr ivers. The CPU can manipulat e data in a buffer before
copying it, all at once, to a disk drive. While this improves syst em performance --- readin g to or writing
from a disk drive a single time is much fa ster than doing so repeatedly --- there is also the possi bility of
losing your data should the system cr ash. Inf ormatio n sto re d in a bu ffer is te mp orarily st ore d, n ot p ermanently saved.
Attachment Packet Interface): also known as IDE or ATA; a drive implementation that includes
IOS Boot Specification): is a fea ture within the BIOS that crea tes, prio ritizes, an d maintains a list
asic Input/Output System): the program that resides in the ROM chip, an d provides the basic
Bus: a data pathway. The term is used especially t o refer to the connec tion bet ween the pr ocessor 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).
Cache: a temporary storage area for data that will be needed often by an application. Using a cache lowers data access times, since th e ne ed ed i n for mat ion is stored in the SRAM instea d o f in the slow DRA M .
Note that the cache is also mu ch sm al le r th an your re gu lar m em or y: a typi ca l cach e size i s 51 2KB , wh ile
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 amoun t of m emory wh ich ca n be sc anned by the syste m in se arch of da ta to
put into the cache. A ty pical setup would b e a ca che si ze o f 512KB , an d a ca cheable area of 5 12MB. In
this case, up to 512KB 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 (C
the BIOS.
COM port: another name fo r t he seri a l po rt, whi ch is ca l led as su ch beca use i t tr an smits the eig ht b i ts o f
a byte of data along one w ire , an d re cei ve s da ta on another single wi re ( tha t is , th e da ta is transmitted in
serial form, one bit after another) . Parallel ports tran smit the bits of a byte on eight different w ires at the
same time (that is, in parallel form, eight bits at the same time).
DDR (D
and falling edge of the system clock rather than on just the rising edge, potentially doubling output.
DIMM (D
need to be installed in pairs.
DIMM bank: sometim es called DIMM sockets, because the physical slot and th e logical unit are the
same. That is, one DIMM module fits into one DI MM socket, which is capable o f acting as a memory
bank.
DMA (D
(like soundcards 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. Plugn-Play devices will take care of this for you.
Doze mode: in this mode, only the CPU’s speed is slowed.
omplementary Metal-Oxide Semiconductors): chips that hold the basic startup information for
ouble Data Rate): improves RAM speed to at least 200 MHz. It activates output on both the rising

DRAM (Dynamic RAM): wide ly available, very afford able form of RAM whi ch has the unfortunate ten-
dency to lose data if it is not recharged regularly (every few milliseconds). This refresh requirement
makes DRAM three to ten times slower than non-recharged RAM such as SRAM.
EDO RAM (E
addresses are static; the next time it looks for a bit of data, it will be at the same spot, or one nearby.
EEPROM (E

having to buy a new chip. Tyan’s BIOS updates can be found at http://www.tyan.com
ESCD (E
in the system BIOS. This information helps properly configure the system each time it boots.
Fault-tolerance: a term describin g a sy stem w her e one c ompon ent can qu ick ly be re pl aced w itho ut ca us ing a loss of service, such as in a RAID system.
Firmware: low-level software that controls the system hardware.
Form factor: an i nd ust ry t erm fo r the size, sh ape , p ow er su ppl y typ e, a nd ext ern al c onn ecto r type of the
Personal Computer Board (PCB) or motherboard. The standard form factors are the AT and ATX,
although Tyan also makes some Baby-AT and ATX Footprint boards.
Global timer: onboard hardware timer, such as the Real-Time Clock (RTC).
Handshaking: a form of encryp tion. 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 H

ard Disk Drive, a type of fixed drive.
H-SYNC: controls the horizontal synchronization/properties of the monitor.
ntegrate d Circuit): the formal name for the computer chip.
IC (I
ntegrated Device/Drive Electronics): a simple, self-contained HDD interface. It can handle drives up
IDE (I
to 8.4 GB in size. Almost all IDE s sold now are in fact Enhanced IDEs (EIDEs), with maximum capa city
determined by the hardware controller.
IDE INT (IDE Interrupt): a hardware interrupt signal that goes to the IDE.
I/O (I
nput/Output): the connection between your computer and another piece of hardware (mouse, key-
board, etc.)

Initial Program Load ( IPL): a feature built into BBS-compliant devices, describing those devices as
capable of loading and execu ting an OS, as w ell as being able to pro vide control ba ck to the B IOS if the
loading attempt fails.
IRQ (Interrupt Request): 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 t o each IRQ line; d oubling u p devices o n IRQ lin es can lock u p your sys tem.
Plug-n-Play operating systems can take care of these details for you.
ISA (I
ndustry Standard Architecture): a slower 8- or 16-bit bus (data pathway).
Latency: the amount of time that one part of a system spends waiting for another part to catch up. This is
most common when the syste m s end s da ta o ut t o a per iphe ra l device, and it waiting for th e p erip heral to
send some data back (peripherals tend to be slower than onboard system components).
Mirroring: see RAID.
NVRAM: ROM and EEPROM are both examples of Non-Volatile RAM, memory that holds its data without
power. DRAM, in contrast, is volatile.
OEMs (O
and hardware inside their case and sell them.
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 (P
bus. Local buses are those which operate within a single system (as opposed to a ne twork bus, which
connects multiple systems).
PCI PIO (PCI P
modes use the C PU for dat a transfer ( in contrast, D MA channel s 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: a fast secondary cache. It is used as a secondary cache because SRAM is slower
than SDRAM, but usually large r. Data is cached first to the fa ster prim ary cache, and then, when the pr imary cache is full, to the slower secondary cache.
Pipelining: improves system perform ance by allowing the CPU to begin exe cuting a second instru ction
before the first i s com pleted. A pipeline can be l ike ned to a n assembly line, wit h a g i ven pa rt of th e p i peline repeatedly executing a set part of an operation on a series of instructions.

PM timers (Pow e r M ana gem en t time rs) : software timers that count down the num ber of se con ds or mi n-
utes until the system times out and enters sleep, suspend, or doze mode.
PnP (P
lug-n-Play): a design standard that has become ascendant in the industry. Plug-n-Play devices
require little set-up to use. Novice end use rs can simply plu g them into a compu ter that is run ning on a
Plug-n-Play aware operatin g system ( such as Win dows 98), and go to wo rk. Devices a nd oper ating systems that are not Plug-n-Play require you to reconfigu re your system each time you ad d or change any
part of your hardware.
Striping: see RAID.
RAID (R
edundant Array of Independ ent Disks): a way for the same dat a to be stor ed in different places
on many hard drives. B y using this m ethod, the data is sto red redundan tly, also the multiple hard drives
willl appear as a single drive to the operating system. RAID level 0 is is known as striping, where data is
striped (or overlapped) across multiple hard d r ives, but offers no fault-tolerance. RAID level 1 is known as
mirroring, which stores th e data within at least two hard dr ives, but does not stripe. RAID level 1 also
allows for faster access time and fault-toleranc e, since either hard dr ive can be read at the s ame time.
RAID level 0+1 is both str iping and mir roring, providing fault-toler ance, striping, an d faster access all at
the same time.
RAM (R
andom Access Memory): technically refers to a type of memory where any byte can be accessed
without touching the adjacent data, is ofte n used to refer to the system’s main memory. This memory is
available to any program running on the computer.
ROM (R
ead-Only Memory): a storage chip wh ich contains the BIOS ; the basic instructions req uired to
boot the computer and start up the operating system.
SDRAM (S
addresses open simultaneo usly. By transferring data alternat ely from one set of ad dresses and th en the
other, SDRAM cuts down on the delays associated with non -synchronous RAM, which mus t close one
address bank before opening the next.
Serial port: called as such because it tran smits 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 (S
must be installed in pairs, and do not have the carrying capacity or the speed of DIMMs.
SIMM bank/socket : SIMM s ockets are the physical slots into which you install SIM M modules. A pair o f
SIMM sockets form a SIMM bank, and act as one unit. If only one socket is filled, the bank will not op erate.
Sleep/Suspend mode: in this mode, all devices except the CPU shut down.
64
ynchronous Dynamic RAM): called as such because it can keep two sets of memory
ingle In-line Memory Module): formerly the most common form of RAM f or motherboa rds. They

Page 65
SRAM (Static RAM): unlike DRAM, thi s type of RAM doe s not need to be refreshed in o rder to preven t
data loss. Thus, it is faster, and more expensive.
Standby mode: in this mode, the video and fixed disk drive (usually the HDD) shuts down; all other
devices continue to operate normally.
UltraDMA/33/66/100: a fast version of the old DMA channel. UltraDMA is also called UltraATA. Without
the proper UltraDMA controller, your system cannot take advantage of the higher data transmission rates
of the new UltraDMA/UltraATA HDDs.
USB (U
niversal Serial Bus): a ver satile port. T his one po rt type ca n functi on as a serial, pa ral lel, mouse ,
keyboard, or joystick port. It is fas t enough to supp ort video transfer, and is capable of supp orting up to
127 daisy-chained peripheral devices.
VGA (V
ideo Graphics Array): the PC video display standard.
V-SYNC: controls the vertical properties of the monitor.
