LV-669 User’s Manual Introduction
Chapter 1 <Introduction>
1.1 <Product Overview>
LV-669 is the Mini-ITX motherboard based on VIA chipset. It integrates VIA embedded
chipset for CN700 with VT8237R Plus, DDR 333/400 SDRAM, and serial ATA with RAID to
provide the economical embedded platform.
VIA CN700 & VT8237R Plus Chipset
The board comes with the VIA embedded chipset of CN700, supports DDR 333/400
SDRAM, integrated the S3 Graphics UniChrome Pro IGP graphics core, hardware MPEG-2
acceleration.
The VT8237R Plus provides the board to support Ultra V-Link (533MB/s) with CN700, two
serial ATA ports with RAID array function, 6 x USB2.0 ports and 5.1 channel AC97 audio.
Multimedia solution
Based on VIA CN700 chipset, the board provides 18/24-bit LVDS interface or DVI, which
supports dual independent display with CRT.
Onboard AC97 codec provides the high quality of sound including 5.1-channel stereo
DACs.
Two LAN Interface
LV-669 also comes with two Giga LAN interface, support boot-on-LAN and wake-on-LAN
function.
High Speed Hot-plug Interface
Based on VIA VT8237R Plus the board provides 6 USB2.0 interfaces with up to 480Mbps of
transferring rate.
Expanded UCR for remote Operating SETUP Bios Feature
Expanded Universal Console Redirection (UCR) is a feature for monitoring POST
messages and running Setup and an operation system from a remote serial terminal.
