LV-66A User’s Manual Hardware Setup
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 assignm ent 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 LV-66AX, 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 +12v +5V or +3.3V.
3. You would need a LVDS type cable.

Chapter 3 <System Configuration>
3.1 <SATA RAID Configuration>
The board supports four Serial ATA ports onboard, and supports RAID 0, 1, 0+1, 5 and
JBOD disk array, the RAID 0, 1, 0+1, 5 and JBOD are specified below:
RAID 0 (Stripping): Stripe Arra y is also called RAID 0, it implements a striped disk array
and the data is broken down into blocks in which each block is written to a separate disk
drive. I/O performance is greatly improved by spreading the I/O load across many channels
and drives. Best performance is achieved when data is striped across multiple channels
with only one drive per channel.
RAID 0 is not a "True" RAID because it is NOT fault-tolerant. The failure of just one drive
will result in all data in an array being lost. It should never be used in mission critical
environments.
RAID 1 (Mirroring): Mirror Array is also called RAID 1; it provides 100% data redundancy.
No rebuild is necessary in case of a disk failure, simply copy data from the remaining
healthy disk to the replacement disk.
You can specify a disk as the auto-selected replacement disk for a Mirror Array; this
replacement disk is called Spare Disk.
To add/remove Spare Disk for a Mirror Array, please refer to Add/Remove Spare. You can
also select an ordinary disk to replace the failed disk in a Mirror Array, instead of using a
Spare Disk for auto-replacement.
RAID 0+1: RAID 0+1 is implemented as a mirrored array whose segments are RAID 0
arrays. It has the advantages both provided by RAID 0 (high I/O performance) and RAID 1
(fault tolerance).
At least four disks are needed to create a RAID 0+1 disk array.
RAID5 (Parity RAID): RAID5 Array uses block-level striping with parity data distributed
across all member disks. It requires a minimum of 3 disks to implement. It has highest read
data transaction rate and medium write data transaction rate. When one of the disks in
RAID5 failed, the data in RAID5 can also be accessed, and the broken RAID5 disk arra y
can be repaired with a new disk.

LV-66A User’s Manual
JBOD (Span): Span Array is also called JBOD (Just a Bunch Of Disks), which uses a
bunch of disks as a larger disk. Span provides no fault tolerance and no I/O performance
enhancement, it's just a measure to enlarge disk capacity.

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 sta ndard 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 ＜DEL＞ key i mmediately 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.
