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 c able, becaus e
every panel has its own pin assignment, so we do not provide a standard cable; ple ase fin d
a local cable manufacture to make cables.
LCD Installation Guide:
1. Preparing the LE-379, LCD panel and the backlight inverter
2. You would need a LVDS type cable.

Chapter 3 <BIOS Setup>
The motherboard uses the phoenix BIOS for the system configuration. The
Phoenix 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 modif y 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 provi ded
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 ＜DEL＞ key 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 e nter the CMOS Setup Utility,
the Main Menu will be displayed as Figure 4-1. You can use arrow keys to select

Note：GPIO using Open-drain.
GPIO0…..GPIO7 bit0……bit7
-o 2E 87 ;enter configuration.
-o 2E 87
-o 2E 07
-o 2F 09 ;select logic device 9.
-o 2E 30
-o 2F 02 ;active GPIO3.
-o 2E F0
-o 2F xx ;set GPIO as input/output; set ‘1’ for input,’0’for
output.
-o 2E F1
-o 2F xx ;if set GPIO’s as output,in this register its value can
be set
Optional :
-o 2E F2
-o 2F xx ; Data inversion register ; ‘1’ inverts the current valus
of the bits ,’0’ leaves them as they are
