Step 18. 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.

24

Hardware Setup SY-7IZB+

2. Select [STANDARD CMOS SETUP]

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

3. Select [SOYO COMBO SETUP]

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

Available [CPU Frequency] settings on your SY-7IZB+ Motherboard
are detailed in the following table. You are then required to fill in the
next two consecutive fields: (1) the CPU Host/PCI Clock, and (2) the
CPU Frequency.

CPU Frequency

300MHz (66 x 4.5)
333MHz (66 x 5.0)
366MHz (66 x 5.5)
400MHz (66 x 6.0)
433MHz (66 x 6.5)
466MHz (66 x 7.0)
500MHz (66 x 7.5)

Select the working frequency of your Celeron

TM

processor among these preset values.

Note: Mark the checkbox that
corresponds to the working frequency of your
Celeron TM processor in case the CMOS
configuration should be lost.

Note: if you use Bus Frequencies of 75 MHz, make sure that
your PCI cards can cope with the higher PCI clock.

25

Hardware Setup SY-7IZB+

4. Select [SAVE & EXIT SETUP]

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

Troubleshooting at First Start

l What should I do if the Motherboard refuses to start?
The 66MHz 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 frequency 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 19. 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

DRIVERS INSTALLATION

Your SY-7IZB+ 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.

60

Driver Installation SY-7IZB+

Step 2. Install Drivers and Utilities

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

Please select the driver you want to install and click OK, You will have to
restart your system after installation. Only the drivers that are relevant
to your board are displayed initially.

Intel Southbridge Drivers
SOYO Speedpro BusMaster Driver for win 95/98

(Driver Installation Menu)

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.

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

62

Driver Installation SY-7IZB+

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.

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.

63

Driver Installation SY-7IZB+

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.

For example:
Newer Celeron CPUs have a core voltage of 2.0V. Therefore, set

the CPU Vcore limits to 1.8V and 2.2V.

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.

Step 3. Check the Latest Releases

Click the 'Check the latest Releases' button to go the SOYO
Website to automatically find the latest BIOS, manual and driver
releases for your motherboard. This button will only work if your
computer is connected to the internet through a network or modem
connection. Make sure to get your modem connection up before
clicking this button.

Step 4. Enter the SOYO CD

Click the Enter SOYO CD button to enter the SOYO HTML
database. The Start Up program will activate the default HTML
browser installed on your system (for example, Internet Explorer or
Netscape) to visualize the contents of the SOYO CD.
The SOYO CD contains useful information about your Motherboard
and other SOYO products available in as many as eleven different
languages. For your convenience, this information is available in
HTML format, similar to the format widely used on the Internet.

64

Driver Installation SY-7IZB+

Step 5. Select which driver you want to install and

click OK

Notice 1: You may click Cancel to abort the driver installation and
return to the main menu.

Notice 2: 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.
