LV-674 User’s Manual Introduction
Chapter1 <Introduction>
1.1 <Product Overview>
LV-674 is the motherboard with last Intel desktop technology with Mini-ITX form factor.
Based on Intel® 945G and ICH7R, the board integrates a new Pentium 4 processor 775-pin
socket, DDR2 memory socket, Intel® Graphic Media Accelerator 950 technology, PCI
express interface and Serial ATA II with RAID function for a powerful desktop system.
Intel® LGA775 processor
The Intel® Pentium 4 processor now comes with a new form factor with 775-pin PLGA
package, for 533/800/1066MHz front-side-bus, 1MB L2 cache, and for 90nm manufacturing
technology, the PLGA processor without pin header on solder side can make user installing
the processor on the socket easier.
Intel® 945G and ICH7R chipset
The Intel 945G integrates DDR2 400/533/667MHz for memory, and Graphic Media
Accelerator (GMA) 950 technology for new graphic engine. It can provide up to 224MB of
frame buffer when you install over 256MB of system memory. The ICH7R integrates with up
to 4 USB2.0 interfaces (4 ports for LV-674), and serial ATA II interface with RAID function.
Four Marvell E8053
Four Gigabit LAN with Marvell E8053, LV-674 comes with a powerful network function for
the system that requires large transfer data of NAS system or Server platform.
PCI-Express interface
LV-674 integrates a x16 PCI-Express interface, it can provide up to 8GB/s of ban dwidth,
which AGP 8x can only provide up to 2GB/s.
Multimedia interfaces
LV-674 also integrates 7.1 channel AC97 audio, mini-PCI interface and IEEE1394 port, for
these flexible function, system integrator can built more powerful systems for many
applications.

2.17 <Expansion Interface>
LV-674 has one PCI-Express 16x slot and one Mini-PCI socket onboard. PCI-Express is the
last expansion interface technology, for its serial data transfer scheme, each lane will be up
to 500MB/s (duplex), and the 16x (16 lanes) can be up to 8GB/s more tha n 2GB/s as AGP
8x bus transfer rate. The 16x slot can be also for x1 compatible use.
PCIE (PCI-Express x16 slot)
Mini-PCI Card installation:
1. Slot in the card at 45 degree
2. Press the card onto the socket
to hear a click sound

SA TA Mode:
This option can let you select whether the Serial ATA hard drives would work under normal
IDE mode or RAID mode. The RAID mode need more than one HDD is applied.
Once you enable the RAID mode, the boot-up screen would pop up the RAID configuration
option for setup.

On-Chip Serial ATA mode:
This option can let you select operation modes of Serial ATA drives.
Disabled: To disable the onboard Serial ATA controller.
Auto: To allow the system select the optimized mode automatically.
Combined mode: PATA and SATA work as two channels for supporting two drives on each
channel.
Enhanced mode: Max supported of the PATA and SATA for up to 6 drives.
SATA Only: To disable the PATA and only apply the SATA drives.
Notice: The Combined mode and Enhanced mode are supported depends on your
operating system, please check page35 for relative information.

3.2 <SATA RAID Configuration>
The board integrates Intel® ICH7R with RAID function for Serial ATA II drives, and supports
the configurations below:
RAID 0 (Stripping): Two hard drives operating as one drive for optimized data R/W
performance. It needs two unused drives to build this operation.
RAID 1 (Mirroring): Copies the data from first drive to second drive for data security, and if
one drive fails, the system would access the applications to the workable drive. It needs two
unused drives or one used and one unused driv e to build this operation. The second drive
must be the same or lager size than first one.
RAID 5 (striping with parity)
A RAID 5 array contains three or more hard drives where the data is divided into
manageable blocks called strips. Parity is a mathematical method for recreating data that
was lost from a single drive, which increases fault-tolerance. The data and parity are striped
across all the hard drives in the array. The parity is striped in a rotating sequence to reduce
bottlenecks associated with the parity calculations.
RAID 10 (RAID 0+1)
A RAID 10 array uses four hard drives to create a combination of RAID levels 0 and 1. The
data is striped across a two-drive array forming the RAID 0 component. Each of the drives
in the RAID 0 array is then mirrored by a RAID 1 component.
Intel Matrix Storage Technology: This technology would allow you to use RAID 0+1 mode
on only two drives (4 drives needed on traditional RAID 0+1). It will create two partitions on
each hard drive to simulate RAID 0 and RAID 1. It also can let you modify the partition size
without re-formatted.
For more information of Intel Matrix Storage Technology, please visit Intel’s website.
If you need to install an operation system on the RAID set, please use the driver disk
attached in the package when it informs you to obtain the RAID drivers.

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 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.
