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 conne ctor to make a c able, becaus e
every panel has its own pin assignment, so we do not pro vide a standard cable; ple ase find
a local cable manufacture to make cables.

LCD Installation Guide:

1. Preparing the LP-172, 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. T he 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 l et 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 ＜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. W hen 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.
