Step 14. External Suspend Button (JP10)

Some cases come with a suspend button, insert the plug into JP10.
In addition to through this button, the system can also enter the
suspend mode through your OS.

Note: Suspend mode only functions if your Power Management

mode is APM. Make sure that the BIOS setting for Power
Management is APM. Windows 98 can be installed with ACPI Power
Management (default is APM), in this case suspend mode will not
function either.

Step 15. Power On

You have now completed the hardware installation of your
Motherboard successfully.

1. Turn the power on

2. To enter the BIOS Setup Utility, press the <DEL> key while the

system is performing the diagnostic checks,

Note: If you have failed to enter the BIOS, wait until the boot
up sequence is completed. Then push the RESET button and
press <DEL> key again at the beginning of boot-up, during
diagnostic checks.

Step 16. Quick BIOS Setup

This Motherboard does not use any hardware jumpers to set the
CPU frequency. Instead, CPU settings are software configurable
with the BIOS [SOYO COMBO SETUP]. The [SOYO COMBO
SETUP] menu combines the main parameters that you need to
configure, all in one menu, for a quick setup in BIOS.
After the hardware installation is complete, turn the power switch on,
then press the <DEL> key during the system diagnostic checks to
enter the Award BIOS Setup program. The CMOS SETUP UTILITY
will display on screen. Follow these steps to configure the CPU
settings.

1. Select [LOAD SETUP DEFAULT]

Select the “LOAD SETUP DEFAULT” menu and type “Y” at the
prompt to load the BIOS optimal setup.

2. Select [STANDARD CMOS SETUP]

Set [Date/Time] and [Floppy drive type], then set [Hard Disk Type] to

28

Hardware Setup SY-6IBM

“Auto”.

3. Select [SOYO COMBO SETUP]

Move the cursor to the [CPU Speed] field to set the CPU working
frequency, as shown in the following display.

Available [CPU Speed] settings on your SY-6IBM Motherboard are
detailed in the following table. If you set this field to [Manual], you
are then required to fill in the next two consecutive fields: (1) the
CPU Ratio, and (2) the CPU Frequency.

CPU Frequency

233MHz (66 x 3.5) 350MHz (100 x 3.5)
266MHz (66 x 4.0) 400MHz (100 x 4.0)
300MHz (66 x 4.5) 450MHz (100 x 4.5)
333MHz (66 x 5.0) 500MHz (100 x 5.0)
366MHz (66 x 5.5) 550MHz (100 x 5.5)

400MHz (66 x 6.0) 600MHz (100 x 6.0)
433MHz (66 x 6.5)

Select the working frequency of
your Pentium® III, Pentium® II,
Celeron processor among
these preset values.

Note: Mark the checkbox
that corresponds to the working
frequency of your Pentium® III,
Pentium® II, Celeron
processor in case the CMOS
configuration should be lost.

4. Select [SAVE & EXIT SETUP]

Press <Enter> to save the new configuration to the CMOS memory,
and continue the boot sequence.

29

Hardware Setup SY-6IBM

Troubleshooting at First Start

l What should I do if the Motherboard refuses to start?
The 350MHz setting is used as default so whenever the BIOS

settings are erased or reset, the board will be able to boot up.
If the CPU speed was set too high and the Motherboard refuses to
start up, you can always load the default values by pressing the [Ins]
key during boot up.

Step 17. Power Off

There are two possible ways to turn off the system:

1. Use the Shutdown command in the Start Menu of Windows

95/98 to turn off your computer.

2. Press the mechanical power-button and hold down for over 4

seconds, to shutdown the computer. If you press the power­button for less than 4 seconds, then your system will enter into

Suspend Mode.

You are now ready to configure your system with the BIOS setup
program. Go to Chapter 3: BIOS SETUP

A joystick, in computer graphics, is a lever with at least two degrees
of freedom used as an input device. The joystick is normally used as
a locator in at least a 2-D plane.
The joystick device is most widely used in video games applications.
Attach the joystick cable to the 15-pin JOYSTICK port at the rear
panel of your Motherboard.

4-2 ONBOARD AUDIO

This Motherboard features three built-in audio-stereo ports (labeled
line-in, line-out, and mic jack) convenient to directly plug-in all your
external audio devices. Your SY-6IBM Motherboard is making use of
the YAMAHA YMF740 sound chipset technology and applications
programs.

Note: Please refer to Chapter 5- YAMAHA Sound Driver Installation
for a detailed procedure on how to install the audio driver depending
on the particular environment (Win NT 3.5/4.0, Win 95/98) installed
on your system.

4-2.1 Connecting your Audio Devices

You can connect audio devices to the following ports:

l headphones or pre-amplified speakers to the "line-out" port;
l a line-in device such as CD/Cassette player to the "line-in" port;
l a microphone to the "mic" port.

Using the YAMAHA™ YMF-740 Audio Driver

To access the YAMAHA™ Sound Mixer audio driver controls, follow
these steps:

1. Open the Windows 95/98 [Start] menu.

2. Select [Programs], [Accessories], and [Multimedia] path.

3. Find and click the [Volume Control] option to run the
application.

The audio control panel of the YAMAHA™ sound driver will appear.
The audio mixer gives control of the sound inputs of all audio
devices. You can adjust the internal volume and balance of each
individual audio device. Also, this audio mixer lets you apply wave
sound effects.

Important: The [Playback] volume controls the master
output sound volume of your system. Depending on the
speaker you use you will need to adjust both the volume
control on the speaker itself and the audio volume control
menu under Windows 95/98 to get the proper sound output.

DRIVERS INSTALLATION

Your SY-6IBM Motherboard comes with a CD-ROM labeled "SOYO
CD." The SOYO CD contains the user's manual file for your new
Motherboard, the drivers software available for installation, and a
database in HTML format with information on SOYO Motherboards
and other products.

The SOYO CD Start Up Program automatically detects which SOYO
Motherboard you own and displays the corresponding model name.

Step 1. Insert the SOYO CD into the CD-ROM drive

The SOYO CD will auto-run, and the SOYO CD Start Up Menu will
display as shown below.

68

Drivers Installation SY-6IBM

Step 2. Install Drivers

Click the Install Drivers button to display the list of drivers software
that can be installed with your Motherboard. The Start Up program
displays the drivers available for the particular model of
Motherboard you own. We recommend that you only install those
drivers.

The following drivers are available for Windows 95

(Driver Installation Menu)

69

Drivers Installation SY-6IBM

The following drivers are available for Windows 98

(Driver Installation Menu)

A short description of all available drivers follows:

Ø Intel Southbridge Drivers
Because Windows 95 does not recognize the Southbridge of the
newer Intel chipsets (TX, BX, ZX etc) this utility has to be run, it will
update the necessary Windows files. (Only for Windows 95)

Ø SOYO SpeedPro Busmaster Driver for Win 95/98
Without the busmaster drivers the CPU will need to be involved
every time data is read from or written to the Harddisk. The
busmaster drivers make use of DMA (Direct Memory Access) to
relieve the CPU of this burden, thus speeding up the system.

The SOYO SpeedPro driver makes use of an advanced caching
algorithm, which gives it an advantage over other busmaster drivers.

70

Drivers Installation SY-6IBM

Ø Intel Busmaster Drivers for Windows 95
Ø Intel Busmaster Drivers for Win NT
Ø Intel Busmaster Drivers for OS/2

These are the official busmaster drivers as supplied by Intel.

Note: Do NEVER install two types of busmaster drivers on

your system, this will lead to conflicts and system instability.
Therefore, if you install the SOYO SpeedPro Busmaster
driver you can NOT install the Intel Busmaster drivers.
Before installing a new busmaster driver first UNINSTALL the
old busmaster driver.

Ø SOYO CD Xpress Utility
This utility will enhance your CD-ROM Drive data-thoughput by
using space on the Harddisk as cache. This way application
programs can access data faster. This utility is suitable for Windows
95/98.

Ø Winbond hardware doctor for Windows xx
Your motherboard comes with a hardware monitoring IC. By
installing this utility Temperature, Fan speed and Voltages can be
monitored. It is also possible to set alarms when current system
values exceed or fall below pre-set values.

Because the Hardware monitor comes with default monitoring
settings that may not be appropriate to the configuration of the
actual system, it is possible that the user will have to change some
of these settings.

l Core voltage
The core voltage differs between generations of Intel CPUs, if the
Hardware monitor gives a warning, the settings for the safe range of
the core voltage has to be adjusted. This can be done by simply
clicking and dragging the upper and lower limit bars.

71

Drivers Installation SY-6IBM

For example:
Newer Slot 1 CPUs have a core voltage of 2.0V. Therefore, set the
CPU Vcore limits to 1.8V and 2.2V. For 2.8V core voltage CPUs the
limits would be 2.6V and 3.0V.

l Fan speed
The Hardware monitor can keep track of three fans. If the user does
not use all fans, the fans that are not in use should be disabled in the
Hardware monitor program, otherwise the Hardware monitor will
give an alarm. If this happens, make sure to disable monitoring for
that fan.

Ø YAMAHA 740 Sound Drivers for Win95/98 and Win NT
With this application program the user can make use of the on board
sound chip. Before installing the YAMHA 740 Sound Drivers, you
MUST first install the YAMAHA 740 drivers for Windows 9x or NT.

Ø ATI Rage 128 AGP
Select this Item and click OK to start up the ATI Rage 128 AGP
driver screen. Follow the instructions on the screen to install the
drivers and/or application programs you need.

However, to display the list of all drivers software available with
SOYO Motherboards, click the Display all drivers on the SOYO CD
button. Please make sure to install only the drivers adapted to your
system, or otherwise this cause system malfunctions.

73

Drivers Installation SY-6IBM

Step 3. Select which driver you want to install and

click OK

Notice 1: Once you have selected a driver, the system will
automatically exit the SOYO CD to begin the driver installation
program. When the installation is complete, most drivers require to
restart your system before they can become active.

Notice 2: You may click Cancel to abort the driver installation and
return to the main menu.

Notice 3: Once you have selected a driver, the system will
automatically exit the SOYO CD to begin the driver installation
program. When the installation is complete, most drivers require you
to restart your system before they can become active.
