Page 17
SAHARA System User Guide
The SAHARA System not only employs the latest breakthroughs in personal
computing technology but also complies with accepted international safety,
regulatory and ergonomic standards for maximum compatibility.
The SAHARA System comes with two serial ports, two USB ports, one parallel port
with ECP/EPP, one Audio connector (Line-In, Line-Out, MIC-In), one RJ45 LAN
connector, two PS/2 connectors, one D-sub 15-pin female VGA port, one
Game/MIDI port (optional), one IrDA port (optional), and two expansion slot
openings, allowing you to connect your computer to a wide variety of input-output
devices such as mice, printers, modems, and graphics tablets. This User Guide is
provided to help you get the most out of your new investment. It describes all the
features of the SAHARA System in an easy-to-read yet thorough manner. The
primary goals of this chapter are (1) to introduce the computer’s features and (2) to
identify the computer’s external components. The chapter begins with instructions for
unpacking your new SAHARA System.
Unpacking the SAHARA System
Before unpacking the SAHARA System, prepare a suitable workspace for your
computer. Provide a steady, level and clean surface, near an electrical wall outlet. If
you are using a Fax/Modem, make sure that the workspace is located near a
telephone jack. Also ensure that the computer has enough space around it to allow for
airflow, especially at the rear of the computer near the fan. If the computer does not
have enough ventilation, internal components can become overheated and may
become damaged.
Using a computer for extended periods of time, a poor
workstation set-up, and incorrect work habits can create health
problems. The science of ergonomics studies the relationship
between health and a suitable work environment. For more
information on ergonomics, contact your nearest computer
bookstore, or local library.
When opening the box for your computer, make sure that you do not damage the box.
You may need it in the future for shipping or storing your SAHARA System.
When you have unpacked your computer, make sure the following items are included
in the box and are in good condition. If you find that any of these items are missing
or appear damaged, contact your SAHARA System dealer immediately.

Setting Up the SAHARA System
Place the computer system in a site that is clean, well-ventilated and near a grounded
(three-pronged) outlet. If the computer does not have enough ventilation, internal
components may overheat and become damaged. If you are using a Fax/Modem make
sure the workspace is near a telephone jack.
If the line voltage in your area is unreliable, you may want to
use a voltage regulator to protect the system from possible
harmful effects caused by sudden electrical surges.
Although the computer system is designed and built to work and last for a long time,
you may do well to heed the following precautions to get the most out of the system:

Operating System
A computer starts up only when there is an operating system (O/S) existing on
its hard disk or when a system diskette is in its primary drive, normally designated as drive A. Think of the operating system or user interface as the translator between the computer chip and you. The computer chip sits there with its
tremendous computing power, but it needs a way to tell you what is going on
and you need a way to tell it what you want it to do. You communicate through
the user interface.
Most computers are sold with an operating system pre-installed. If this is true
of your computer, you can be sure that the hard disk ispre-formatted andcontains the files necessary for booting.
If the hard disk is not yet formatted and the O/S not yet installed into it, read
carefully the related manuals for instructions in the proper hard disk formatting
and running of the Setup program of MS-DOS.
The computer automatically loads the O/S after you turn it on. This process is
called booting.
If you are booting from a system diskette, see the section on Diskette Operations to know how to insert diskettes into the drive.
If you are booting from the hard disk, proceed with the following instructions.

After completing the system connections described in the Section System
Connections on page 15. You can link with your local area network by simply
following the steps listed in Appendix C.
Power-On Operations
1.Turn on the computer by pressing the power button.
Each time the system power is turned on, the system runs a series of tests,
commonly referred to as POST (Power-On-Self-Test) which checks the status
of major computer devices that include the mainboard, memory, video, keyboard, and disk drive. Some status messages of POST appear on the screen.
POST compares the current hardware setup status with the default configuration information pre-entered into the system BIOS Setup. (See Chapter 4 for
details on the BIOS Setup settings.)
2.When POST detects a mismatch between the actual hardware configuration
and the BIOS Setup default settings, error messages indicating invalid
configuration appears on the screen. Normally, the message specifies the cause
of the problem, thereby giving you a hint on how to fix the problem.
When you see such an error message, refer to Chapter 5 on Troubleshooting
Tips in this manual to know how to solve the problem. If the error message
persists or if the problem is not discussed in the Troubleshooting Tips chapter,
consult your dealer or a qualified service technician for assistance.
3.When no mismatch is found and POST successfully completes its check, the
computer first tries to boot from drive A. If there is no diskette in drive A, the
computer boots from the hard disk, usually designated as drive C.
When the computer boots from the hard disk that has an operating system
properly installed on it, the system prompt, usually the C:> prompt appears.
The appearance of the C:> prompt signifies successful booting or start-up of
the system. You could now start installing or using the application programs
like MS-Windows.

Diskette Operations
Inserting/Removing Diskettes
Floppy disks are the portable storage system for your computer, similar to file
folders for your work. On floppy disks you can store the projects created in
the computer, make an extra copy or carry them to another computer.
When you are starting up the system for the very first time, the disk drives
probably will have the cardboard head protector inserted into the drive.
1.Remove the cardboard head protector from the disk drive. Press the ||||||||||||| |
eject button to pull out the cardboard. Keep the cardboard for future ||||||||||||||
use in case you may have to move the system.
2. If the system does not have a hard disk and an operating system, insert a
system diskette (that comes with the operating system diskettes and contains
the COMMAND.COM file).
When you insert a diskette in the floppy disk drive (FDD), insert the diskette
with the label side up and the metal plate first into the drive until the diskette
locks in place.
3. To remove a diskette from the FDD, press the diskette eject button to make the
diskette come out partway out of the drive and gently pull out the diskette by
hand.
18
When the system is accessing the drive (indicated by the lit in-use
indicator), be careful not to remove a diskette or accidentally press
the power button. Doing so may destroy the data on the diskette
and may damage the drive mechanism.
Even though the 3.5-inch floppy diskette are encased in a hard
plastic coating, they should be treated with care.

Diskette Types
The type of diskette that you can use in a disk drive depends on the drive size.
See the following table to know the drive/diskette compatibility features:
DRIVE CAPACITYDISKETTE DENSITYREAD/WRITE
High Capacity
1.44MB 3.5 inch
Standard Capacity
720KB 3.5 inch
* To format a standard-density diskette in a high-capacity drive,
you must include certain parameters in the formatting command.
Refer to the operating system documentation for details.
Note that the capacity of a standard-density diskette will not
change when it is formatted in a high-capacity drive.
A standard-capacity disk drive might not be able to read a
standard-capacity diskette that was written or formatted in a highdensity drive.

Backing Up Master Diskettes
Master diskettes are the original diskettes of the operating system or software
programs. As a safeguard against unexpected damage or alterations, make back
up copies of the master diskettes and use the backup diskettes for everyday operation. Store the master diskettes in a safe place. Consult the MS-DOS or MSWindows documentation to know how to properly back up diskettes.
The hard disk has a much larger capacity and faster access speed than the
floppy disk drive. For your convenience, you are advised to copy frequentlyused program files from your MS-DOS or utility diskettes or other application
programs into your hard disk so you can run the programs from there.
One of the most important uses of floppy disks is to back up your work so that
if anything happens to the copy that is on the hard drive (hard drives can crash
and erase all your work) you have a copy. Get in the habit of making backup
copies of your work often. Store a copy at another location for extra protection.
As folks in the computer world always say, “It isn’t a question of if your hard
drive will crash, only a question of when.”

Resetting the Computer
You may re-start the system (that is, go through booting and POST operations
again) without turning the computer power off and on again. There are two
ways to do this:
1. Press the Reset button on the front panel of the system.
2. Remove the diskette, if any, from the disk drive.
3. Turn off the computer by pressing the Power Button.
4. Turn off the power of any connected external devices.
If you are using any MS Windows-based program, make sure you shut it
down first before turning off system power:
1. Save and close any open files. Though most programs will remind you to save
your work if you forget, taking the initiative to save your work is a good habit
to form.
2. Click the Close button for the program window.
3. If you have no unsaved documents, the program closes and you return
immediately to the Windows desktop.
4. If you have an unsaved work or a work containing unsaved changes, the
program asks you whether to save it. Click on “Yes” to save it or on “No” to
abandon it.
5. If you click on “Yes” and the document has never been saved before, the Save
As dialog box appears. Name and save your work.
6. To turn off your computer after closing the program, it’s very important to
shut down Windows first. Click the Start button, then click on the Shut Down
option to display the Shut Down Windows dialog box.
7. Click the “Yes” button, then wait until you see the message “It’s now safe to
turn off your computer.” before you turn the computer off.

MAKING UPGRADES EASY
Before You Begin
We recommend that you contact your SAHARA System reseller for carrying out any
system upgrades. The following upgrades to the system are best if attempted only by
a qualified technician.
Make sure you have a stable and clean working environment. Dust and dirt can get
into computer components and cause malfunction. Use containers to keep small
components separated. Many of the screws on the computer are of different sizes; if
you place them together you may spend a lot of time trying to track down the correct
screw when you are assembling the computer back together. Also, placing all small
components in a safe container keeps them from getting lost. Having adequate
lighting and using proper tools can prevent you from accidentally damaging the
internal components. Most of the procedures that follow require only a few simple
tools, including the following:
• A Philips screwdriver
• A flat tipped screwdriver
• A set of jeweler’s screwdriver
• A multimeter (not always required)
• A grounding strap
23
Page 39
SAHARA System User Guide
Most of the electrical connections can be disconnected by using your fingers. It is
recommended that you do not use needle-nosed pliers to disconnect connections as
this can damage the soft metal or plastic parts of the connectors. Many connectors
have tabs to keep them secure. After the tabs are disengaged the connector should
easily slide out. You can use a small screwdriver to gently pry some of the connectors
loose. If the connector does not come out easily, make sure that nothing is
obstructing it, and gently rock it back and forth in its slot until it loosens enough to
come out. Do not force it!
Before working on internal components, make sure that the computer’s power is off.
Ground yourself before touching any internal components by touching a metal object.
Static electricity can damage many of the computer’s electronic components. Humid
environments tend to have less static electricity than dry environments. A grounding
strap is warranted whenever danger of static electricity exists.
Removing the Chassis Cover
1. Turn the power of the system unit off and all connected peripherals.
2. Disconnect all power cords and cables from the system unit.

BIOS SETUP
The system comes with the Award BIOS chip that contains the ROM Setup
information of the system. This chip serves as an interface between the processor and
the rest of the system's components. This chapter explains the information contained
in the Setup program and tells you how to modify the settings according to the
system configuration.
The BIOS ROM of the system stores the Setup utility. When you turn on the
computer, the system lets you run this program. This appears during the Power-OnSelf-Test (POST). Press the <Delete> key to call up the Setup utility. If you are a
little bit late pressing the mentioned key(s), POST will continue with its test routines,
thus preventing you from calling up Setup. If you still need to call Setup, reset the
system by simultaneously pressing the <Ctrl>, <Alt> and <Delete> keys, or by
pushing the Reset button on the system case.

BIOS Setup
Standard CMOS Setup
The “Standard CMOS Setup” option allows you to record some basic system
hardware configuration and set the system clock and error handling. If the mainboard
is already installed in a working system, you will not need to select this option
anymore. However, if the configuration stored in the CMOS memory on the
mainboard gets lost or damaged, or if you change the system hardware configuration,
you will need to re-specify the configuration values. The configuration values usually
get lost or corrupted when the power of the onboard CMOS battery weakens.
The above screen provides you with a list of options. At the bottom are the control
keys for this screen. Take note of these keys and their respective uses. Userconfigurable fields appear in a different color. If you need information on the
selected field, press the <F1> key. The help menu will then appear to provide you
with the information you need. The memory display at the lower right-hand side of
the screen is read-only and automatically adjusts accordingly.
Date
To set the date, highlight the “Date” field and then press the page up/page down or
+/– keys to set the current date. Follow the month, day and year format. Valid values
for month, day and year are: Month: (1 to 12), Day: (1 to 31), Year: (up to 2079).
Time
To set the time, highlight the “Time” field and then press the page up/page down or
+/– keys to set the current time. Follow the hour, minute and second format. Valid

Hard Disk Drive
This field records the specifications for all non-SCSI hard drives installed in the
system. The onboard PCI IDE connectors only provides a Primary channel for
connecting to one IDE hard disk.
For IDE hard disk drive setup, you can:
n Use the Auto setting for detection during bootup.
n Use the IDE HDD AUTO DETECTION in the main menu to automatically enter
the drive specifications.
n Enter the specifications yourself manually by using the “User” option.
The entries for specifying the hard disk type include CYLS (number of cylinders),
HEAD (number of read/write heads), PRECOMP (write precompensation), LANDZ
(landing zone), SECTOR (number of sectors) and MODE. The SIZE field
automatically adjusts according to the configuration you specify. The documentation
that comes with the hard disk should provide you with the information regarding the
drive specififcations.
The MODE entry is for IDE hard disks only, and can be ignored for MFM and ESDI
drives. This entry provides four options: Normal, Large, LBA, or Auto. Set MODE to
Normal for IDE hard disk drives smaller than 528MB; set it to LBA for drives over
528MB that support Logical Block Addressing (LBA) to allow larger IDE hard disks;
set it to Large for drives over 528MB that do not support LBA. Large type of drive
can only be used with MS-DOS and is very uncommon. Most IDE drives over
528MB support the LBA mode.
Auto Detection of Hard Disks on Bootup
For the Primary Master field, you can select Auto under the TYPE and MODE fields.
This will enable auto detection of your IDE drive during Bootup. This will allow you
to change the hard drive (with the power off) and then power on without having to
reconfigure the hard drive type. If you use an older hard drive which do not support
this feature, then you must configure the hard drive in the standard method as
described above by the “User” option.

the drive letter on the screen. The process then proceeds to the next drive letter.
Pressing the <N> key to skip rather than to accept a set of parameters causes the
program to enter zeros after that drive letter.
When auto-detection is completed, the program automatically enters all entries you
accepted on the field for that drive in the Standard CMOS Setup screen. Skipped
entries are ignored and are not entered in the screen.
If you are auto-detecting a hard drive that supports the LBA mode, three lines will
appear in the parameter box. Choose the line that lists LBA for an LBA drive. Do not
select Large or Normal.
The auto-detection feature can only detect one set of parameters for a particular IDE
hard drive. Some IDE drives can use more than one set. This is not a problem if the
drive is new and there is nothing on it.

TROUBLESHOOTING
The system is built to last long and perform its multi-functions with utmost efficiency. It is also user-friendly, both in its normal operations and when it encounters a system problem. It alerts you to possible problems by way of screen
messages that also give you the correct instructions to solve the problem.
This chapter offers some possible solutions to potential problems that you
might have with the computer.
Determining Problem Causes
To facilitate troubleshooting when encountering problems while operating the
computer, it is important to find out if the cause is software-related or hardware-related. It is suggested that you record the observations of events immediately prior to and during the time you encounter the problem.
If the problem is software-related, consult the software manual of the application you are using. If the problem is hardware-related, it may be due to improper installation and/or incorrect configuration. If it is due to improper
installation, then any or a combination of the following corrective procedures
should solve the problem:
Chapter 5
n Check the installation or connection to see if it is correctly done or firmly
in place.
n Check if the installation calls for a change in jumper settings or DIP
switch settings.
n Read the document accompanying the hardware option you installed for
any special instructions or troubleshooting actions.

SAHARA System User Guide
Excessive torque may damage the mainboard. When using an
electric screwdriver on the mainboard, make sure that the torque is
set to the allowable range of 5.0 ~ 8.0kg/cm.
Mainboard components contain very delicate Integrated Circuit
(IC) chips. To prevent static electricity from harming any of the
mainboard’s sensitive components, you should follow some
precautions whenever working on the computer:
1. Unplug the computer when working on the inside.
2. Hold components by the edges and try not to touch the IC chips,
leads, or circuitry.
3. Wear an anti-static wrist strap which fits around the wrist.
4. Place components on a grounded anti-static pad or on the bag
that came with the component whenever the components are
separated from the system.
1). Set System Jumpers
Jumpers are used to select the operation modes for your system. Some jumpers on the
board have three metal pins with each pin representing a different function. A “1” is
written besides pin 1 on jumpers with three pins. To set a jumper, a black cap
containing metal contacts is placed over the jumper pin/s according to the required
configuration. A jumper is said to be shorted when the black cap has been placed on
one or two of its pins. The types of jumpers used in this manual are shown below:

SAHARA System User Guide
2). Install RAM Modules
SDRAM
The working space of the computer is the Random Access Memory (RAM). The
system cannot act upon data unless it is loaded into RAM. When more memory is
added, the working memory of the computer is larger, thereby increasing total
performance. The mainboard RAM is comprised of two 168–pin Dual In–line
Memory Modules (DIMMs). Each DIMM socket is able to support up to 128MB
lightning-fast SDRAM.
SDRAM is an advanced new memory technology that helps boost overall system
performance with its ability to synchronize all operations with the processor clock
signal. This makes the implementation of control interfaces easier, and speeds up
column access time. SDRAM features an on–chip burst counter that can be utilized to
increment column addresses for very fast burst access, which means that SDRAM
allows new memory access to be initiated before the preceding access has been
finished.
Before making DRAM upgrades you should verify the type and speed of the RAM
currently installed from your dealer. Installing mixtures of RAM types other than
those described in this manual will have unpredictable results.
RAM Module Configuration
The mainboard provides two onboard DIMM sockets allowing 3.3V (unbuffered)
SDRAM DIMM modules. Either 8, 16, 32, 64, or 128MB DIMM can be installed on
these two sockets. The maximum total memory supported is up to 256MB.

x1256MB
Install DIMMs
SDRAM DIMM modules have different pin contact on each side and therefore have a
higher pin density. Complete the following procedures when installing DIMMs:
Do not use memory modules with more than 24 chips per module.
Modules with more than 24 chips exceed the design specifications
of the memory subsystem and will be unstable.
The notch on the DIMM module will shift between left, center, or
right to identify the type and also to prevent the wrong type from
being inserted into the DIMM slot on the mainboard. Ask your
retailer for the specifications before purchasing.
1. Locate the DIMM slots on the mainboard. (See the following figure.)
2. Install the DIMM straight down into the DIMM slot with both hands.
71
Page 87
SAHARA System User Guide
3. The clip on both ends of the DIMM slot will close up to hold the DIMM in place
when the DIMM touches the slot’s bottom.
Remove DIMMs
Press the clips with both hands to remove the DIMM.
3). Install the Central Processing Unit (CPU)
If the mainboard is for the Pentium® II CPU, then it comes with an onboard
Retention Mechanism, a Heatsink with Fan, and two clips for attaching the Heatsink
with Fan to the CPU cartridge. If any piece is missing, please contact your local
system dealer to help you. If the mainboard is for the Celeron™ CPU, then it comes
with an onboard Retention Mechanism, a Passive Heatsink, and a clip for attaching
the Passive Heatsink to the CPU.
The Retention Mechanism is already installed onboard by the
manufacturer.
CPU Cartridge and Heatsink with Fan Installation (for
Pentium® II CPU)
To install the CPU cartridge and Heatsink with Fan, refer to the following steps:
1. Peel off the backing tape located on the flat side of the Heatsink with Fan.
2. Carefully position the Heatsink with Fan on the center of the CPU cartridge, taking
care to align the two protruding knobs of the Heatsink with Fan to the holes on the
thermal plate side of the CPU cartridge, with the fan on the right side facing you.

SAHARA System User Guide
The mainboard features one 32-bit EISA bus expansion slot.
This section describes how to connect an expansion card to the system's riser card.
An expansion card is a printed circuit board that, when connected to the mainboard,
allows you to increase the capabilities of the system. For example, expansion cards
can provide video and sound capabilities.
Always turn the system power off before installing or removing any
device. Always observe static electricity precautions. See
“Handling Precautions” at the start of this manual.
To install an expansion card, follow the steps below:
1. Remove the computer chassis cover (see Chapter 3 “Removing the Chassis
Cover”) and locate the riser card on the EISA expansion slot (SL1).

Mainboard Installation Procedures
2. Remove the corresponding slot cover from the computer chassis. Unscrew the
mounting screw that secures the slot cover and swing open the slot holder
securing plate prior to pulling the slot cover out from the computer chassis. Keep
the slot cover mounting screw nearby.
3. Read the expansion card documentation on any hardware and software settings that
may be required to setup the specific card.
4. Set any necessary jumpers on the expansion card.
5. Select an empty expansion slot on the riser card.
6. Holding the edge of the peripheral card, carefully align the edge connector with the
expansion slot.
7. Push the card firmly into the slot. Push down on one end of the expansion card,
then the other. Use this “rocking” motion until the add–on card is firmly seated
inside the expansion slot.

8. Swing close the slot holder securing plate and secure the board with the mounting
screw removed in Step 2. Make sure that the card has been placed evenly and
completely into the expansion slot.
9. Replace the computer system’s cover. (See Chapter 3 “Re-installing the Chassis
Cover”.)
10. Setup the BIOS if necessary.
11. Install the necessary software drivers for the expansion card.

5). Connect Cables and Power Supply
Connectors
Some pins are used for connectors or power sources. These are
clearly separated from jumpers. Placing jumper caps over these
will cause damage to the mainboard.
Ribbon cables should always be connected with the red stripe on the Pin 1 side of the
connector. The four corners of the connectors are labeled on the mainboard. Pin 1 is
the side closest to the power connector on hard drives and floppy drives.
Connectors allow the mainboard to link electronically with other parts of the system.
Some malfunctions encountered may be caused by loosed or improper connections.
Ensure that all connections are in place and firmly attached.
Serial Port Connectors: COM1, COM2
These two 9–pin D-sub male connectors allow you to connect with your devices that
use serial ports, such as a serial mouse or a modem. Usually, it is recommended to
connect the serial mouse to COM1 and the fax/modem to COM2.

PS/2 Keyboard and Mouse Connector: MS, KB
These two 6–pin female connectors are used for your PS/2 keyboard and PS/2 mouse.
The PS/2 keyboard connector is for a standard keyboard using a PS/2 plug (mini
DIN). This connector will not allow standard AT size (large DIN) keyboard plugs.
You may use a DIN to mini DIN adapter on standard AT keyboards.
The system will direct IRQ12 to the PS/2 mouse if one is detected. If not detected,
expansion cards may be using IRQ12.
Printer Connector: LPT
This 25–pin D-sub female connector is attached to your printer. Serial printers must
be connected to the serial port.

CPU Fan Connector: CPU_FAN
This connector is linked to the CPU fan. When the system is in suspend mode, the
CPU fan will turn off; when it reverts back to full–on mode, thefan will turn back
on. The picture below shows the type of CPU fan with heatsink for your system.
Without sufficient air circulation, the Pentium® II CPU
cartridge may overheat and cause damage to both the CPU
cartridge and the mainboard.
Damage may occur to the mainboard and/or the CPU fan if
these pins are incorrectly used. These are not jumpers, do
not place jumper caps over these pins.
