CHAPTER 2 Installation This chapter provides you with information about hardware installation procedures. It is recommended to use a grounded wrist strap before handling computer components. Electrostatic discharge (ESD) can damage some components.
Installation CPU The VIA EPIA-CN Mini-ITX mainboard includes an embedded VIA C7 V4 Bus Processor. The VIA C7 V4 Bus Processor requires only a heatsink to provide sufficient cooling.
Chapter 2 CPU Fan and System Fan: CPUFAN and SYSFAN The CPUFAN (CPU fan) and SYSFAN (system fan) run on +12V and maintain system cooling. When connecting the wire to the connectors, always be aware that the red wire is the Positive and should be connected to the +12V. The black wire is Ground and should always be connected to GND. FAN_MCM is a switch that is used by high-quality fans to monitor the system temperature and will automatically adjust according to the environment.
Installation MEMORY MODULE INSTALLATION The VIA EPIA-CN Mini-ITX mainboard provides one 240-pin DIMM slot for DDR2 533/400 SDRAM memory modules and supports the memory size up to 1GB. DIMM DDR SDRAM Module Installation Procedures • Locate the DIMM slot in the motherboard. • Unlock a DIMM slot by pressing the retaining clips outward. • Align a DIMM on the socket such that the notch on the DIMM matches the break on the slot.
Chapter 2 CONNECTING THE POWER SUPPLY The VIA EPIA-CN Mini-ITX mainboard supports a conventional ATX power supply for the power system. Before inserting the power supply connector, always make sure that all components are installed correctly to ensure that no damage will be caused. ATX 20-Pin Power Connector To connect the ATX power supply, make sure the power plug is inserted in the proper orientation and the pins are aligned. Then push down the plug firmly into the connector.
Installation BACK PANEL PORTS The back panel has the following ports: Keyboard and Mouse The green 6-pin connector is for a PS/2 mouse. The purple connector is for a PS/2 keyboard. Serial port: COM 1 The green 9-pin COM 1 port is for pointing devices or other serial devices. VGA Out The blue 15-pin female VGA connector can be used to connect to any analog VGA monitor.
Chapter 2 RJ45 10/100 LAN and USB Connector The mainboard provides a standard RJ-45 and USB 2.0 ports. These ports allow connection to a Local Area Network (LAN) through a network hub and USB 2.0 devices. USB 2.0 ports These two 4-pin Universal Serial Bus (USB) ports are available for connecting USB 2.0 devices. RCA / SPDIF jack The yellow jack connects to external composite video device or audio output device.
Installation Audio Port: The Line-Out jack is for connecting to external speakers or headphones. The Line-In jack is for connecting to an external audio device such as a CD player, tape player, etc. The Mic jack is for connecting to a microphone. Note: The audio ports can be switched to Smart 5.1 6-channel audio output. You can enable the function by clicking the “Vinyl Audio” icon on your desktop after installing the audio driver.
Chapter 2 CONNECTORS Hard Disk Connectors: IDE1 & IDE2 The mainboard has a 32-bit Enhanced IDE and Ultra DMA 133/100 controller that provides PIO mode 0~4, Bus Master, and Ultra DMA 133/100 functions. You can connect up to four hard disk drives, CD-ROM and other devices. The primary hard drive should always be connected to IDE1 as the master drive. Both IDE drives can connect to a master and a slave drive.
Installation Case Connector: F_PANEL The F_PANEL pin header allows you to connect the power switch, reset switch, power LED, sleep LED, HDD LED and the case speaker. Pin Signal Pin Signal F_PANEL 1 3 5 7 9 11 13 15 +5VDUAL +5VDUAL -PLED +5V NC NC SPEAK Key 2 4 6 8 10 12 14 16 +5V HD_LED PW_BN GND RST_SW GND +5V -SLEEP_LED 1 2 15 16 Power Switch (PW_BN) Connect to a 2-pin power button switch. Pressing this button will turn the system power on or off.
Chapter 2 Serial ATA Connectors: SATA1 and SATA2 SATA1-2 These next generation connectors support the thin Serial ATA cables for primary internal storage devices. The current Serial ATA interface allows up to 150MB/s data transfer rate, faster than the standard parallel ATA with 133 MB/s (Ultra DMA). USB Pin Connector: USB 4-7 The mainboard provides 1 front USB pin header, allowing up to 4 additional USB2.0 ports up to maximum throughput of 480 Mbps. Connect each 2-port USB cable into this pin header.
Installation Front Panel Audio Connector: F_AUDIO This is an interface for the VIA front panel audio cable that allow convenient connection and control of audio devices. By default, the pins labeled LINE_OUT_R/NEXT_R and the pins LINE_OUT_L/NEXT_L are shorted with jumper caps. Remove the caps only when you are connecting the front panel audio cable.
Chapter 2 LPT Connector: LPT The mainboard provides a 26-pin connector to be able to connect a 25-pin female external connector for LPT (parallel port). A parallel port is a standard printer port that supports Enhanced Parallel Port (EPP) and Extended Capabilities Parallel Port (ECP) modes.
Installation JUMPERS The mainboard provides jumpers for setting some mainboard functions. This section will explain how to change the settings of the mainboard functions using the jumpers. Clear CMOS: CLEAR_CMOS The onboard CMOS RAM stores system configuration data and has an onboard battery power supply. To reset the CMOS settings, set the jumper on pins 2 and 3 while the system is off. Return the jumper to pins 1 and 2 afterwards. Setting the jumper while the system is on will damage the mainboard.
Chapter 2 SLOTS Peripheral Component Interconnect: PCI The PCI slot allows you to insert PCI expansion card. When adding or removing expansion card, unplug first the power supply. Read the documentation for the expansion card if any changes to the system are necessary. PCI PCI Interrupt Request Routing The IRQ (interrupt request line) are hardware lines over which devices can send interrupt signals to the microprocessor.

CHAPTER 4 Driver Installation This chapter gives you brief descriptions of each mainboard driver and application. You must install the VIA chipset drivers first before installing other drivers such as audio or VGA drivers. The applications will only function correctly if the necessary drivers are already installed.
Chapter 4 DRIVER UTILITIES Getting Started The mainboard includes a Driver Utilities CD that contains the driver utilities and software for enhancing the performance of the mainboard. If the CD is missing from the retail box, please contact the local dealer for the CD. Note: The driver utilities and software are updated from time to time. The latest updated versions are available at http://www.viaembedded.com.
Driver Installation Running the Driver Utilities CD To start using the CD, insert the CD into the CD-ROM or DVD-ROM drive. The CD should run automatically after closing the CD-ROM or DVD-ROM drive. The driver utilities and software menu screen should then appear on the screen. If the CD does not run automatically, click on the “Start” button and select “Run…” Then type: "D:\Setup.exe". NOTE: D: might not be the drive letter of the CD-ROM/DVD-ROM in your system.
Chapter 4 CD CONTENT VIA 4in1 Drivers: Contains VIA ATAPI Vendor Support Driver (enables the performance enhancing bus mastering functions on ATA-capable Hard Disk Drives and ensures IDE device compatibility), AGP VxD Driver (provides service routines to your VGA driver and interface directly to hardware, providing fast graphical access), IRQ Routing Miniport Driver (sets the system's PCI IRQ routing sequence) and VIA INF Driver (enables the VIA Power Management function).
