Chapter 1 <Introduction>  
1.1 <Product Overview>  
LE-366 is the Mini-ITX motherboard with AMD Geode LX800 platform, with onboard VGA,  
AC97 audio, GIGA LAN interface. Based on the AMD Geode LX800 processor, the board  
provides many advanced features for reduced power consumption, fan-less design and  
high cost/price rate of production.  
Low Power Consumption  
Based on the AMD Geode LX800@500MHz processor onboard, it only takes up to 3.8W at  
maximum powering, and is completely suitable for fan-less design. Without any cooling fan  
onboard, it can avoid the heat problem when the cooler failed in accidence.  
Onboard TFT/LVDS LCD interface  
Based on the AMD Geode LX800@500Mhz of integrated graphics and 18-bit LVDS  
interfaces.  
Embedded Component  
Due to the low profile design, the board provides CF card socket for flash disk with porting  
embedded OS and up to DDR SDRAM.  
Single Voltage Input  
The board only requires DC 12V input. User’s can easily connect the board with an adapter  
without the huge power supply.

LE-366 User’s Manual  
To setup the LCD, you need the component below:  
1. A panel with LVDS interfaces.  
2. An inverter for panel’s backlight power.  
3. A LCD cable and an inverter cable.  
For the cables, please follow the pin assignment of the connector to make a cable, because  
every panel has its own pin assignment, so we do not provide a standard cable; please find a  
local cable manufacture to make cables.  
LCD Installation Guide:  
1. Preparing the LE-366, LCD panel and the backlight inverter.  
2. Please check the datasheet of the panel to see the voltage of the panel, and set the  
jumper JP1 to +5V or +3.3V.  
3. You would need a LVDS type cable.

Chapter 3 <BIOS Setup>  
The motherboard uses the Award BIOS for the system configuration. The Award BIOS in  
the single board computer is a customized version of the industrial standard BIOS for IBM  
PC AT-compatible computers. It supports Intel x86 and compatible CPU architecture based  
processors and computers. The BIOS provides critical low-level support for the system  
central processing, memory and I/O sub-systems.  
The BIOS setup program of the single board computer let the customers modify the basic  
configuration setting. The settings are stored in a dedicated battery-backed memory,  
NVRAM, retains the information when the power is turned off. If the battery runs out of the  
power, then the settings of BIOS will come back to the default setting.  
The BIOS section of the manual is subject to change without notice and is provided here for  
reference purpose only. The settings and configurations of the BIOS are current at the time  
of print, and therefore they may not be exactly the same as that displayed on your screen.  
To activate CMOS Setup program, press DELkey immediately after you turn on the  
system. The following message “Press DEL to enter SETUP” should appear in the lower left  
hand corner of your screen. When you enter the CMOS Setup Utility, the Main Menu will be  
displayed as Figure 4-1. You can use arrow keys to select your function, press Enter>  
key to accept the selection and enter the sub-menu.
