balance between performance and power on-the-fly. The S3
Graphics PowerWise Technology brings together graphics
performance and power efficiency for embedded systems.

VIA VT1708 High Definition Audio Codec

The VIA VT1708 delivers top quality audio performance —
supporting the latest 8-channel, 24-bit, 192 kHz audio content for
an all-round high-fidelity experience. Integrating stereo DACs with
a 100 dB signal-to-noise ratio, the VIA VT1708 includes features
such as a high quality headphone amplifier, enhanced recording
support, and advanced power management.

VIA VT1211 Super I/O

The VIA VT1211 is a full function Super I/O chip with a floppy disk
controller, an IEEE-1284 parallel port interface, two 16C550-UART­based serial port interfaces, a VFIR (Very Fast IR) controller, a game
port that supports two joysticks, a MIDI interface, and a 4 MB
Flash-ROM interface.

Its integrated hardware monitor controller controls the speed of
up to two fans, monitors two fan tachometers, and five universal
analog inputs for measuring voltage or temperature. The VT1211
is ACPI ready with a hardware monitor engine built-in to monitor
system health.

Note:

System resources (such as BIOS, PCI, etc.) require physical
memory address locations that reduce available memory
addresses above 3 GB. This may result in less than 4 GB of
memory being available to the operating system and
applications.

With certain limitations, DVI-I (default display) can support DVI-D + CRT using a Y-cable

1. CRT will always show the same content with the primary display device from the S3G 435ULP.

2. CRT may not display correctly due to the timing limitation. Users may need to choose a specific CRT panel if
this function is desired.

CPU

The VIA VB8003 Mini-ITX mainboard is packaged with a VIA Nano

1.6 GHz NanoBGA2. The processor requires a heatsink with fan to

provide sufficient cooling.

CPU and SYS Fan: CPUFAN1 and SYSFAN1

The CPUFAN (CPU fan) and SYSFAN (System fan) runs on +12V
and maintains CPU and system, cooling. When connecting the
cable to the connector, always be aware that the red wire
(positive wire) should be connected to the +12V pin. The black
wire is the ground wire and should always be connected to GND.

Onboard Jumpers

The mainboard provides jumpers for setting some mainboard
functions. This section will explain how to change the settings of
the mainboard functions using the jumpers.

41

Clear CMOS: CLEAR_CMOS

The onboard CMOS RAM stores system configuration data and has
an onboard battery power supply. To reset the CMOS settings, set
the jumper on pins 2 and 3 while the system is off. Return the
jumper to pins 1 and 2 afterwards. Setting the jumper while the
system is on will damage the mainboard. The default setting is on
pins 1 and 2.

Caution:

Except when clearing the RTC RAM, never remove the cap from

cap will cause system boot failure. Avoid clearing the CMOS
while the system is on; it will damage the mainboard.

PC HEALTH STATUS

The PC Health Status displays the current status of all of the
monitored hardware devices/components such as CPU voltages,
temperatures and fan speeds.

DRAM Frequency

The chipset supports synchronous and asynchronous mode
between host clock and DRAM clock frequency.

Spread Spectrum

When the mainboard's clock generator pulses, the extreme values
(spikes) of the pulses create EMI (Electromagnetic Interference). The
Spread Spectrum function reduces the EMI generated by
modulating the pulses so that the spikes of the pulses are reduced
to flatter curves.

Settings: [Disabled, +/- -0.1%, +/- -0.2%, +/- -0.3%, +/- -0.4%, +/- -

This option is for restoring all the default optimized BIOS settings.
The default optimized values are set by the mainboard
manufacturer to provide a stable system with optimized
performance.

SET SUPERVISOR/USER PASSWORD

This option is for setting a password for entering BIOS Setup.
When a password has been set, a password prompt will be
displayed whenever BIOS Setup is run. This prevents an
unauthorized person from changing any part of your system
configuration.

There are two types of passwords you can set. A supervisor
password and a user password. When a supervisor password is
used, the BIOS Setup program can be accessed and the BIOS
settings can be changed. When a user password is used, the BIOS
Setup program can be accessed but the BIOS settings cannot be
changed.

To set the password, type the password (up to eight characters in
length) and press <Enter>. The password typed now will clear any
previously set password from CMOS memory. The new password
will need to be reentered to be confirmed. To cancel the process
press <Esc>.

To disable the password, press <Enter
new password. A message will show up to confirm disabling the
password. To cancel the process press <Esc

Additionally, when a password is enabled, the BIOS can be set to
request the password each time the system is booted. This would
prevent unauthorized use of the system. See “Security Option” in
the “Advanced BIOS Features” section for more details.

Driver Installation

This chapter gives you brief descriptions of each mainboard driver
and application. You must install the VIA chipset drivers first before
installing other drivers such as VGA drivers. The applications will
only function correctly if the necessary drivers are already installed.

89

DRIVER UTILITIES

Getting Started

The VIA VB8003 includes a driver CD that contains the drivers and
software for enhancing the performance of the system. The drivers
can also be downloaded from http://www.viaembedded.com

Note:
The driver utilities and software are updated from time to time.
The latest updated versions are available at

http://www.viaembedded.com

Running the Driver Utilities CD

To start using the CD, insert the CD into the CD-ROM or DVD­ROM drive. The CD should run automatically after closing the CD­ROM or DVD-ROM drive. The driver utilities and software menu
screen should then appear on the screen. If the CD does not run
automatically, click on the “Start” button and select “Run…” Then
type: "D:\Setup.exe".

For Linux drivers, click the right button on mouse and click open.
Linux drivers located in the “Driver” folder.

Note:
D: might not be the drive letter of the CD-ROM/DVD-ROM in
your system.
