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 LV-677, 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 JVLCD to +5V or +3.3V.
3. You would need a LVDS type cable.

Chapter 3 <System Setup>
3.1 <Video Memory Setup>
Based on Intel® 945GM(E) chipset with GMA (Graphic Media Accelerator) 950, the
board supports Intel® DVMT (Dynamic Video Memory Technology) 3.0, which would
allow the video memory to be allocated up to 224MB.
To support DVMT, you need to install the Intel GMA 950 Driver with supported OS.
BIOS Setup:
On-Chip Video Memory Size: This option combines three items below for setup.
On-Chip Frame Buffer Size:
This item can let you select video memory which been allocated for leg acy VGA and
SVGA graphics support and compatibility. The available option is 1MB and 8MB.
Fixed Memory Size:
This item can let you select a static amount of page-locked graphics memory which will
be allocated during driver initialization. Once you select the memory amount, it will be no
longer available for system memory.
DVMT Memory Size:
This item can let you select a maximum size of dynamic amount usage of video memory,
the system would configure the video memory depends on your application, this item is
strongly recommend to be selected as MAX DVMT.

Chapter 4 <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 exactl y the same as that displayed on
your screen.
To activate CMOS Setup program, press ＜DEL＞ key immediatel y 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.

-o 2F 40 ;enable GPIO function
-o 2E 07
-o 2F 07 Select Logic Device 7
-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
