Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
! To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.
! Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive electronic components.

System on Module.
Sections include:
! Introduction
! Specification
1.1 Introduction
SOM-4430 is an embedded CPU module that fully complies with the SOM-ETX form
factor standard. The new CPU module supports Advantech EVA-X4300 SOC (system on chip) which supports PCI and ISA interfaces. In a basic form factor of 95 mm
x 114 mm, the SOM-4430 provides a scalable cost effective and easy to integrate
solution for customers’ applications by utilizing a plug-in CPU module on an application-specific customer solution board. The SOM-4430 with advanced I/O capacity
incorporates PCI, ISA, IDE, USB 2.0, and TTL LCD interfaces. SOM-4430 offers
design partners more choices for their own applications needing cost effective solution while maintaining a compact form factor.
The small size (95 mm x 114 mm) and use of four high capacity connectors based on
the proven SOM-ETX form factor, allows SOM-ETX modules to be easily and
securely mounted onto a customized solution board or our standard SOM-DB4400
development board.

3.1 BIOS Introduction
The full-featured AwardBIOS 6.0 is provided by Advantech which delivers superior
performance, and it’s many options and extensions let you customize your products
to a wide range of designs and target markets.
The modular, adaptable AwardBIOS 6.0 supports the broadest range of third-party
peripherals and all popular chipsets, plus Intel, AMD, nVidia, VIA, and compatible
CPUs from 386 through Pentium and AMD Geode, K7 and K8 (including multiple processor platforms), and VIA Eden C3 and C7 CPU.
You can use Advantech’s utilities to select and install features to suit your designs for
your customers needs.
3.2 BIOS Setup
The SOM-4430 system has a built-in AwardBIOS with a CMOS SETUP utility which
allows the user to configure required settings or activate certain system features.
The CMOS SETUP saves the configuration in the CMOS RAM of the motherboard.
When the power is turned off, the battery on the board supplies the necessary power
to the CMOS RAM.
When the power is turned on, press the <Del> button during the BIOS POST (PowerOn Self Test) which will take you to the CMOS SETUP screen.
