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.
4. Check the Tyan user group: alt.comp.periphs.mainboard.tyan

2.2 Installation
You are now ready to install your motherboard. Th e mounting hole patte rn of the Thu nder i840 ma tches
the Extended ATX system board specifications, so your chassis must be capable of supporting an
Extended ATX system 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 wh ich will make
configuration and setup much easier, as well as provide information on device installation and component
set up.. By reading through the manual completely before 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 appear s that they are no t properly sea ted (the boa rd should
still be on an antistatic mat). Do not touc h the bottom of the boa rd. Remember, don’t take any elect ronic
device out o f it s p ro t ect i v e ba g un t i l y o u a r e r e ad y t o a c t ual l y i n s tal l i t int o t he c o mp ute r ca s e . If y o u do n ot
ground yourself, you r isk zappi ng the mothe rboard o r adap ter card . Sub sequen t prob lems 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.

2.7 Mounting the Motherboard into the Chassis
Your chassis may or may not include mounting hardwa re. If mounting h ardware was included, yo u can
use the following 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 the exam ples 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 ail s o n h ow the memory shou 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.
16
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 17
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. 18 and Figure 2.1 (below) for an example.
Outer Module Outer Module
Inner Modules
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

2.9 Installing the CPU and Cooling Fan
Socket370 type Pentium III processors ONLY (500 MHz through 1 GHz) can be used on the Thunder
i840. 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.
Socket370 CPU socket
Installing the Socket370 type CPU
Before installing the CPU, check it for damaged. Make sure that none of the pins are bent. Pin 1 on the
CPU is denoted by a small dot on one of the corners, and Pin 1 on the ZIF socket is denoted by one of the
angled corners (left bottom-most angle from the Intel logo).
INSTALL
Step
Step
Step
Carefully lift the arm of the ZIF socket until it is at a 90-degree angle
1
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.
Push down lightly on the CPU while lowering the arm of the socket
3
to secure the CPU (see right). A squeakin g noise may be hard
while lowering the arm, or the socket may make a ‘click’ noise when
the arm is locked into position: these noises are normal.

Installing the Cooling Fan
After the CPU has been installed, you will need to install the proper cooling device for the CPU. This
device, a heatsink/cooling fan combination, can be purchased from many computer technology vendors.
Connection of the cooling device may vary depending on the fan manufacturer’s design. You should take
space into consideration when installing a cooling device into the CPU1 and/or CPU2 socket(s). Tyan
highly recommends that you use some type of thermal compound between the CPU and heatsink, to
maximize cooling. Please take extra caution when installing any kind of clamp-style fan, or else damage
may occur to the CPU socket. See Figure 2.3 for an example of how the fan power connector is installed.

2.10 Connecting IDE and Floppy Drives
A variety of IDE and ATAPI-compliant devices can be
installed on this motherboard, such as hard disk drives
(HDDs) and CD-ROMs.
Please keep in mind that on this motherboard, the primary IDE connector i s BLACK, and the secondary IDE
connector is WHITE. Figure 2.4 (see right) shows the
IDE cable properly connected to the motherboard. Consult the documentation that came with your device, or
contact the device’s manu fact ure r for de tail s on i ts in stallation. Also see Figure 2.5 (see picture to the right) for
an example of an H DD w ith th e IDE cable install e d. ATA66 IDE HDDs require a special 80-wire, 40-pin IDE cable
which has additiona l grounding wires, and may or may
not have a notch near the blue conne ctor. The cable is
included in the Thunde r i840 motherbo ard packa ge. The
ATA-66 cable is also upwards comp atible with ATA-100
devices, and backwards compatible with ATA-33 and
Legacy IDE HDDs.
The BLUE end of the ATA-66 cable must connect to the motherboard. The black connector on the ATA-66 cable is for the master HDD, and the g rey connec tor is for the
NOTE
slave HDD. See Figure 2.4 for an example of cable installation on the motherboard.
Only Tyan-approved cables are recommended for this mo the rbo ard . If you a re usi ng
an existing configuration with older cables, your system might not function pro perly.
Use only Tyan-approved ca bles (i.e. t he ones tha t were inclu ded with y our motherboard).

2.11 Installing Add-on Cards
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 the following guidelines:
If you are going to install a PCI-bus interface card on your system, be aware that any one of
the 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 to 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.
Check speed of your PCI add-on card and check p. 13 for details on setting the PCI speed.
Before turning on the system, make sure the cards are seated securely into their slots, and that
no cards are touching.
If you follow these ba sic g uid eli ne s, th er e s hou l dn’t be an y p ro blem s w it h in stal la tion. However, if you do
encounter any problems with yo ur add- on cards, co nsult thei r documen tatio n, or have a qualified pro fessional install/troubl eshoot your cards for you, otherwise con tact the card’s manufacturer. Remember,
always read the manuals and insta ll ation note s tha t come wit h the adap ter card s. Th ey con tain im por tan t
information which will help you install the components right, the first time.

A note of caution about installing external devices
When plugging in th e ke ybo ard an d m ou s e, o r w hen pl u ggin g a nyth ing into any external port, make sure
that the power is off. Connecting these de vices and ports while the power is on is called “hot plugging”,
and may damage your system.
2.13 Connecting the power supply
This motherboard req uires an ATX power supply. Tyan recommends using one that conform s to industr y
standard Revision 2.01, an d is 300 watt s or higher. The photos be low show the ATX power connector
before (Figure 2.8a) and after (Figure 2.8b) it has been plugged in. The clip on the power connector
should lock over the tab on the onboa rd conne ctor. You shouldn’t be able to plug the power connector in
more than one way, but just to be safe, make sure it looks like Figure 2.8b. Make certain you do not miss
connecting any of the pins because if you do, you will void your warranty and possible cause damage to
yourself and/or your m otherboard. A fter conn ecting the po wer, make sure the conne ctor is sea ted firmly
into its socket so it will not become loose or fall off when the computer is jostled or moved.

You are done!
Other than checking the jumpe r settings and cable connec tions, and putting the case ba ck on, you are
done. Installing a new motherboard may seem difficult, but by following these directions, you should have
a fairly uneventful time installing our p roducts. If yo u do encounter pr oblems, your dealer will be able to
help you, or you can consult one of our many technical support resources (see p. 7).
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 check and see if you have any device conflicts related to the IRQ, or DMA. If you
are using Microsoft Windows NT/2000, the Control Panel is a good place to start investigating the conflict.
Please consult your op erating system ’s documentation for details. Secondly, slowing down the memory
timing in the BIOS’ chipset setup section will help the situation as well. Many memory modules are not
suitable for high perf orman ce system s and are pr obabl y the main so urce o f your problem . Also check to
make sure you are using a 300W or higher power supply (ATX 2.01 specification or better). Lastly, make
sure the motherboard is receiving adequete cooling.
Q: I have a question about memory compatibility...

Chapter 3: BIOS Setup
Introduction to the BIOS setup
The BIOS is the basic input/output system, required by the computer to perform functions such as CPU
and hard drive support. This chapter describes different settings for AMIBIOS that can be used to configure your system.
The BIOS section of the manual is subject to change without notice and is provided here for reference purposes only. The settings and configurations of the BIOS are current at the time of print,
and therefore they may not be exactly the same as that displayed on your screen.
The manual describes the AMIBIOS setup program. The setup program lets you modify basic configuration settings. The settings are then stored in a dedicated battery-backed memory, called NVRAM, that
retains the information when the power is turned off.
The AMIBIOS in your computer is a customized version of an industry-standard BIOS for IBM PC
AT-compatible personal computers. It supports Intel x86 and compatible processors. The BIOS
provides critical low-level support for the system central processing, memory, and I/O subsystems.
The BIOS has been customized by adding important, but non-standard, features such as virus and
password protection, power mangement, and detailed fine-tuning of the chipset controlling the
system. The rest of this manual is intended to guide you through the process of configuring your
system using the AMIBIOS setup program.
Starting Setup
The BIOS is immediately activated when you first turn on the computer. The BIOS reads system configuration information in CMOS RAM and begins the process of checking out the system and configuring it
through the Power-On Self Test (POST).
When these preliminaries are finished, the BIOS seeks an operating system on one of the data storage
devices (HDD, FDD, etc.) and if one is found, the BIOS will launch that operating system and hand control
of system operations to it. During POST, you can start the setup program by pressing the [DEL] key when
the “Press DEL key to enter BIOS setup” message appears on the screen.

BIOS setup program, you can restart the computer by either:
Pressing [CTRL]+[ALT]+[DEL] (all three keys at the same time)
Holding the power button down until the computer shuts off
The best advice is to alte r only sett ings th at you th oroughl y under stand. I n particu lar, do not change settings in the Chipset scr een un less you ab solutely sure that you ne ed to. Th e C hipse t d efa ults w ere ca refully chosen by AMI or your system manufacturer for the best performance and reliability. Even a

Appendix I: SCSI Installation and LAN Information
Introduction
The Adaptec 7899W enables you to connect up to 30 SCSI devices—such as very large arrays of highperformance HDDs, external storage subsystems, clustered configurations, Ultra160 hard disk drives,
scanners, and CD-ROM drives.
The Adaptec 7899W can support up to two independent SCSI channels, each with a maximum throughput of 160 MBytes/sec. SCSI Channel A (marked* either as “CH 1” or “CH A” on the board) has one internal connector. SCSI Channel B (marked* either as “CH 2” or “CH B” on the board) has one internal
connector.
You can connect Ultra160 and Ultra2 SCSI devices to the 68-pin Low Voltage Differential/Single-Ended
(LVD/SE) connectors on both SCSI channels. Or you can operate the newer Ultra160 and Ultra2 devices
at their maximum speed on Channel B while at the same time using legacy SCSI devices on Channel A.
This installation guide explains how to
• Set up SCSI devices
• Connect SCSI devices
Support for Older SCSI Devices
We recommend that if you have single-ended Ultra SCSI and earlier SCSI devices you connect them to
Channel A of the Adaptec 7899W SCSI and that you connect newer Ultra2 and Ultra160 SCSI devices to
Channel B. This allows the Adaptec 7899W to support newer Ultra160 and Ultra2 SCSI devices at speeds
up to 160 MBytes/sec while at the same time supporting Ultra (legacy) devices at speeds up to 40
MBytes/sec. It also allows you to use longer cable lengths for the newer SCSI devices.
If you connect Wide Ultra/Ultra SCSI devices to the same SCSI channel as
Ultra160 and Ultra2 SCS I devices, the data transfer rate for the Ultra160 and
NOTE:
Setting up SCSI devices
There are several things you may need to do to your SCSI devices before you connect them to the
Adaptec 7899W SCSI:
• Check the SCSI IDs
• Set the termination
• Connect the power cables
* subject to change without notice
42
Ultra2 SCSI devices will drop to Ultra SCSI per formance leve ls. To achieve maximum data transfer rate s for the ne wer SCSI de vices, be sure to conne ct them on
their own SCSI channel.
http://www.tyan.com
Page 43
Since setup can vary from device to device, always refer to the device’s documentation for specific
instructions. Below are some guidelines for setting SCSI IDs and termination on your devices.
Check the SCSI IDs
The Adaptec 7899W and each device you connect to it must have a unique SCSI ID number ranging from
0 to 15 on each channel. No two devices on the same SCSI channel can have the same SCSI ID.
The Adaptec 7899W is preset to ID 7 for each channel and should not be changed. If you boot from a
SCSI hard disk, make sure the hard disk SCSI ID is set to 0. (Most SCSI hard disks are preset to SCSI ID
0 at the factory.) The SCSI IDs for internal devices are usually set with jumpers; SCSI IDs for external
devices are usually set with a switch on the back of the device.
Terminate the Ends
To ensure reliable communication on the SCSI bus, the device at the end of each cable, or the end of the
cable itself, must have a terminator installed (or enabled). Terminators must be removed, or termination
must be disabled, on devices between the ends of each cable.
When connecting Ultra160 or Ultra2 SCSI devices, the SCSI bus must be terminated either on the end of the cable (w ith a pe rma ne nt ter mi na tor ) or with a separate terminating connector. Ultra SCSI and earlier single-ended devices can
NOTE:
terminate the bus directly from th e device. If y ou use an Ultra SC SI termi nator on
an LVD Ultra160 and Ultra2 SCSI bus you will force the bus to Single-ended
mode, limiting the spee d and cable distance. For this reason b e sure that you
have the necessary Ultra160 or Ultra2 cable or terminator befo re installing the
Ultra160 SCSI devices.
Connecting SCSI Devices
You can connect a total of 30 SCSI devices to the Adaptec 7899W,with up to 15 devices on each SCSI
channel. Before connecting devices, be sure to review Setting up SCSI Devices on p. 42.
Connecting Internal Ultra160 and Ultra2 Devices
A special 68-pin internal LVD cable is needed to connect internal Ultra160 or Ultra2 SCSI devices. If your
cables are not marked, you can identify most LVD cables as having twisted pairs of the flat ribbon cable
between the device connectors. Some cables are laminated so that they lay flat. Internal LVD cables usually have a terminator built into the end of the cable.
The Adaptec 7899W has two separate Ultra160 SCSI channels, as shown on the board map on p. 11.
Each channel has an internal LVD/SE connector to which you can connect internal SCSI devices. Follow
these steps to connect your internal Ultra160 and Ultra2 devices:

NOTE:
We recommend that yo u k eep your Ultra160 a nd Ul tr a2 SC SI d evi ce s o n a se parate SCSI channel from your Ultra SCSI devices. This allows the newer Ultra160
and Ultra2 SCSI devices to transfer data at their maximum speed.

Step
Connecting Wide SCSI Devices
You can connect Wide SCSI devices to the internal LVD/SE connectors. If you do this, we recommend
that you connect them to the SCSI Channel A LVD/SE connector and that you connect all Ultra160 and
Ultra2 devices to the SCSI Channel B connector. Follow these steps to connect Wide SCSI devices:
Connect a power cable from your computer’s internal power supply to ea ch internal SCS I

If you have other Ultra/Fast Wide SCSI devices, attach them to the connectors between the
4
two ends of the cable. Be sure these other devices are unterminated.

More information about termination
The last SCSI device on the end of each SCSI bus cable must be terminated, and termination must be
disabled for all other devices in the middle of the cables. Ultra160 and Ultra2 SCSI devices are automatically un-terminated, but Ultra SCSI and Fast/Wide SCSI devices do have termination that you must
check. For more information, refer to the documentation for each SCSI device. If you are using external
Ultra2 or Ultra160 devices, be sure to use an LVD terminator to terminate the last device in the chain. If
you use a single-ended, active terminator (sometimes called an Ultra terminator) the SCSI devices will
not operate at their maximum speed.
If you have any problems while setting up SCSI devices, check the following items first:
• Are all SCSI devices powered on?
• Are all SCSI cables and power cables properly connected?
• Does each device on each SCSI bus have a unique SCSI ID?
• Does the total SCSI cable length exceed the maximum allowable length? (See table below.)
• Is the SCSI bus properly terminated?
If you are still unable to resolve a problem, contact your vendor for help.

Configuring the Adaptec 7899W SCSI with SCSISelect
SCSISelect enables you to change SCSI settings without opening the computer or handling the card.
SCSISelect also enables you to low-level format or verify the disk media of your SCSI hard disk drives.
The following table lists the available and default settings for each SCSISelect option. The settings that
are marked as “Auto-sync” are automatically synchronized for both SCSI channels—for example, if you
change the Boot Channel option to B First on Channel A, the change will apply to Channel B as well. All
other options can be set separately for each of the two SCSI channels.
The default settings are appropriate for most systems and should not be changed. Run SCSISelect if you
need to change or view current settings, or if you need to use the SCSI disk utilities.

SCSI Bus Interface Definitions
• Host Adapter SCSI ID—(Default: 7) Sets the SCSI ID for the SCSI controller. The Adaptec 7899W
is set at 7, which gives it the highest priority on the SCSI bus. We recommend that you do not
change this setting.
• SCSI Parity Checking—(Default: Enabled) When set to Enabled, verifies the accuracy of data
transfer on the SCSI bus. Leave this setting enabled unless any SCSI device connected to the
Adaptec 7899W does not support SCSI parity.
• Host Adapter SCSI Termination—(Default: Automatic) Determines the termination setting for the
SCSI controller. The default setting is Automatic, which allows the SCSI controller to adjust the termination as needed depending on the configuration of the connected SCSI devices. We recommend that you do not change this setting.
Boot Device Options
• Boot Channel—(Default: A First) Specifies which of the two SCSI channels the boot device is con-
nected to (if the computer boots from a SCSI device). If you change this setting, the change automatically applies to both SCSI channels.
• Boot SCSI ID—(Default: 0) Specifies the SCSI ID of your boot device. We recommend that you do
not change the default setting.
• Boot LUN Number—(Default: 0) Specifies which LUN (Logical Unit Number) to boot from on your
boot device. This setting is not valid unless Multiple LUN Support is Enabled
SCSI Device Configuration Options
SCSI Device Configuration options can be set individually for each connected SCSI device.
Note: To configure settings for a SCSI device, you must know its SCSI ID.
• Sync Transfer Rate—(Default: 160) Determines the maximum synchronous data transfer rate that
the SCSI controller supports. We recommend that you leave the maximum (default) value of 160
MBytes/sec.
• Initiate Wide Nego ti ati on—(Default: Yes) When set to Yes, the SCSI controller attempts 16-bit
data transfer (wide negotiation). When set to No, the SCSI controller uses 8-bit data transfer unless
the SCSI device requests wide negotiation.
Note: Set Initiate Wide Negotiation to No if you are using an 8-bit SCSI device that
hangs or exhibits other performance problems with 16-bit data transfer rate enabled.
• Enable Disconnection—(Default: Yes) When set to Yes, allows the SCSI device to disconnect
from the SCSI bus. Leave the setting at Yes if two or more SCSI devices are connected to the SCSI
chip. If only one SCSI device is connected, changing the setting to No results in slightly better performance.
• Send Start Unit Command—(Default: Yes) When set to Yes, the Start Unit Command is sent to
the SCSI device at bootup.
Thunder i840 S2520
49
SCSI & LAN
Page 50
The following three options have no effect if the SCSI BIOS is disabled. (The SCSI BIOS is normally
enabled by default.)
• Enable Write Back Cache—(Default: N/C) Can be used to enable or disable the write-back cache
on SCSI disk drives connected to the host adapter. Leave this option at its default setting of N/C (no
change), which usually allows for optimum drive performance.
• BIOS Multiple LUN Support—(Default: No) Leave this setting at No if the device does not have
multiple Logical Unit Numbers (LUNs). When set to Yes, the SCSI controller BIOS provides boot
support for a SCSI device with multiple LUNs (for example, a CD “juke box” device in which multiple
CDs can be accessed simultaneously).
• Include in BIOS Scan—(Default: Yes) When set to Yes, the SCSI controller BIOS includes the
device as part of its BIOS scan at bootup.
Advanced Configuration Options
Note: Do not change the Advanced Configuration Options unless absolutely necessary.
• Reset SCSI Bus at IC Initialization—(Default: Enabled) When set to Enabled, the SCSI controller
generates a SCSI bus reset during its power-on initialization and after a hard reset.
• Display <Ctrl> <A> Messages during BIOS Initialization—(Default: Enabled) When set to
Enabled, the SCSI BIOS displays the Press <Ctrl> <A> for SCSISelect (TM) Utility! message on
your screen during system bootup. If this setting is disabled, you can still invoke the SCSISelect utility by pressing <Ctrl> <A> after the SCSI BIOS banner appears. If you change this setting, the
change automatically applies to both SCSI channels.
• Extended BIOS Translation for DOS Drives > 1 GByte—(Default: Enabled) When set to
Enabled, provides an extended translation scheme for SCSI hard disks with capacities greater than
1 GByte. This setting is necessary only for MS-DOS 5.0 or above; it is not required for other operating systems.
Caution: Changing the translation scheme destroys all data on the drive. Be sure to
back up your disk drives before changing the translation scheme.
Use the MS-DOS Fdisk command to partition a disk larger than 1 GByte controlled by the SCSI
BIOS, when using DOS.
• Verbose/Silent Mode—(Default: Verbose) When set to Verbose, the SCSI BIOS displays the host
adapter model on the screen during system buildup. When set to Silent, the message will not be
displayed during bootup. If you change this setting, the change automatically applies to both SCSI
channels.
• Host Adapter BIOS (Configuration Utility Reserves BIOS Space)—(Default: Enabled) Enables
or disables the SCSI BIOS. If you change this setting, the change automatically applies to both
SCSI channels.
• Leave at Enabled to allow the SCSI BIOS to scan and initialize all SCSI devices at initial bootup.
• Set to Disabled: Not scan if the devices on the SCSI bus (e.g. CD-ROM drives) are controlled by
software drivers and do not need the BIOS, and you do not want the BIOS to scan the SCSI bus.
• Set to Disabled: Scan Bus if you don’t need the BIOS, but want to scan SCSI devices on the bus.
The following four options on the next page have no effect when the SCSI BIOS is disabled. (The SCSI
BIOS is normally enabled by default.)

• Domain Validation—(Default: Enabled) Determines what kinds of SCSI devices are connected and
reduces data transfer speed if it detects older legacy SCSI devices. Displays the resulting data
transfer rate. If you change this setting, the change automatically applies to both SCSI channels.
• Support Removable Disks Under BIOS as Fixed Disks—(Default: Disabled) Determines which
removable-media drives are supported by the SCSI controller BIOS. The options are as follows:
- Disabled— No removable media drives are treated as hard disk drives. Software drivers are then
required from the vendor, because the drives themselves are not controlled at all by the BIOS.
NOTE: You may lose data if you remove a removable-media cartridge from a SCSI drive con-
trolled by the SCSI controller BIOS while the drive is on. If you want to be able to remove the
media while the drive is on, install the removable-media software driver and set Support
Removable Disks Under BIOS as Fixed Disks to Disabled.
- Boot Only—Only the removable media drive designated as the boot device is treated as an
HDD
- All Disks—All removable media drives supported by the BIOS are treated as HDDs
- BIOS Support for Bootable CD-ROMs—(Default: Enabled) When set to Enabled the SCSI
controller BIOS allows the computer to boot from a CD-ROM drive.
- BIOS Support for Int 13 Extensions—(Default: Enabled) When set to Enabled, the SCSI
controller BIOS supports Int 13h extensions as required by Plug-and-Play. The setting can
be either enabled or disabled if your system is not Plug-and-Play

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.
AMR (A
udio Modem Riser) : a mod em tha t can b e used on Intel Refe rence Mothe rboard platfor ms using
Intel’s core logic chipsets supporting AC-link 2.1. It supports fax and all data feedback modes. It provides
high speed communications between your personal computer and a remove lcoation, such as an Internet
Service Provider (ISP).
AT: the original form factor of IBM’s PC.
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 repl ace 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
center for users to post messages and access information.
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

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 sl ow DR AM .
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

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.

Fault-tolerance: a term describin g a sy stem w her e one com pon ent can qu ick ly be re plac ed w itho ut ca using 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

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
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 (Input/Output): the connection between your computer and another piece of hardware (mouse, keyboard, etc.)
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 her al 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
riginal Equipm ent Manufacturers): Compaq or IBM package other companies’ mother boards
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
eripheral Comp onent Int erconn ect): a 32-b it loc al bus ( data pathw ay) wh ich is faster than the IS A
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 an assembly li ne , with a given part 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 number of seconds or min-
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.
SCSI (S
mall Computer Systems Interface) : prono unce d “scu zzy” . SCSI is an indu stry -sta nda rd comp uter
interface for connecting SCSI devices such as HDDs, CD-ROMs, e tc. to a co mmon SCSI b us. There are
several variations of SCS I, including UltraSCSI, Ultra2 SCSI, Ultra Wide, and so on.
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.
SRAM (S
tatic RAM): unlike DRAM, th is type of RAM does not need t o be refreshed in order to pre vent
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
