SOM-5786 User Manual 2
1.1 Introduction
SOM-5786 is an embedded COM Express Type 2 CPU module that fully complies
with the PCI Industrial Computer Manufactures PICMG COM Express standard. The
new CPU module supports Intel Core Duo / Solo processor by Intel GME965/ICH8-M
chipset which supports faster integrated graphic engine, PCI Express and SATA
interfaces. In a basic form factor of 95 mm x 125 mm, the SOM-5786 provides a scal-
able high performance and easy to integrate solution for customers’ applications by
utilizing a plug-in CPU module on an application-specific customer solution board.
The SOM-5786 with advanced I/O capacity incorporates serial differential signaling
technologies such as PCI Express, Serial ATA, USB 2.0, LVDS, HD Audio and Serial
DVO interfaces. SOM-5786 offers design partners more choices for their own appli-
cations needing higher computing speeds while maintaining a compact form factor.
SOM-5786 complies with the "Green Function" standard and supports Doze, Standby
and Suspend modes. The small size (95 mm x 125 mm) uses two high capacity con-
nectors based on the proven SOM-Express form factor, allowing the SOM-Express
modules to be easily and securely mounted onto a customized solution board or our
standard SOM-DB5700 development board.
The SOM-5786 is a highly integrated multimedia SOM that combines audio, video,
and network functions. It provides high quality TV out, dual channel LVDS interface
for large size TFT LCD display, DDR2 memory up to 4 GB, high definition audio inter-
face (AC97/Azalia), 25 to 112 MHz..

3.1 BIOS Introduction
Advantech provides the full-featured AwardBIOS 6.0 that delivers the superior perfor-
mance, compatibility and functionality that manufactures of Industrial PCs and
Embedded boards demand, 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 pro-
cessor platforms), and VIA Eden C3 and C7 CPU.
You can use Advantech’s utilities to select and install features to suit your customers
requirements.
3.2 BIOS Setup
The SOM-5786 system has build-in AwardBIOS with a CMOS SETUP utility which
allows users to configure required settings or to 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 (Power-
On Self Test) which will take you to the CMOS SETUP screen.
