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.

CPU

The VIA EPIA-EN Mini-ITX mainboard includes an embedded VIA C7 or Eden

V4 Bus Processor. The VIA Eden V4 Bus Processor provides ultra-low power

consumption and advanced thermal dissipation properties and features a

fanless design. The VIA C7 or Eden V4 Bus Processor requires only a

heatsink to provide sufficient cooling.

Installation

CPUFAN

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.

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.

• Firmly insert the DIMM into the slot until the retaining clips snap

back in place and the DIMM is properly seated.

Available DDR SDRAM Configurations

Refer to the table below for available DDR SDRAM configurations on the

mainboard.

ONNECTING THE POWER SUPPLY

The VIA EPIA-EN 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.

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.

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

S-Video port

The black port allows you to connect TV monitor or S-

video device to the mainboard.

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.

After completing the previous installation, connect the speakers to the 3-jack

connectors on the back panel.

Shown below are the corresponding connections to setup the 6-channel

ONNECTORS

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.

If two drives are connected to a single cable, the jumper on the second drive

must be set to slave mode. Refer to the drive documentation supplied by the

vendor for the jumper settings.
