Installation

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.

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.

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.

The PCI slot allows you to insert PCI expansion card. When adding or

removing expansion card, unplug first the power supply. Read the

PCI Interrupt Request Routing

The IRQ (interrupt request line) are hardware lines over which devices can

send interrupt signals to the microprocessor. The “PCI & LAN” IRQ pins are

typically connected to the PCI bus INT A# ~ INT D# pins as follows:

Order 1 Order 2 Order 3 Order 4

PCI Slot 1 INT B# INT C# INT D# INT A#
IEEE1394 INT B#

NOTE: IRQ (Interrupt Request) lines are system resources allocated to

I/O devices. When an I/O device needs to gain attention of the

operating system, it signals this by causing an IRQ to occur. After

receiving the signal, when the operating system is ready, the system

will interrupt itself and perform the service required by the IO device.

The value in this field depends on the memory modules installed in your

system. Changing the value from the factory setting is not recommended

unless you install new memory that has a different performance rating than

the original modules.

SDRAM CAS Latency [DDR/DDR2]

This item is for setting the speed it takes for the memory module to complete

a command. Generally, a lower setting will improve the performance of your

system. However, if your system becomes less stable, you should change it

to a higher setting. This field is only available when “DRAM Timing” is set to

Bank Interleave

This item is for setting the interleave mode of the SDRAM interface.

Interleaving allows banks of SDRAM to alternate their refresh and access

cycles. One bank will undergo its refresh cycle while another is being

accessed. This improves performance of the SDRAM by masking the refresh

time of each bank. This field is only available when “DRAM Timing” is set to

“Manual”.

Settings: [Disabled, 2 Bank, 4 Bank, 8 Bank]

Precharge to Active (Trp)

This field is for setting the length of time it takes to precharge a row in the

memory module before the row becomes active. Longer values are safer but

may not offer the best performance. This field is only available when “DRAM

Timing” is set to “Manual”.

Settings: [2T, 3T, 4T, 5T]

Active to Precharge (Tras)

This field is for setting the length of time it a row stays active before

precharging. Longer values are safer but may not offer the best performance.

Spread Spectrum

When the mainboard's clock generator pulses, the extreme values (spikes) of

the pulses creates EMI (Electromagnetic Interference). The Spread Spectrum

function reduces the EMI generated by modulating the pulses so that the

spikes of the pulses are reduced to flatter curves.

This option is for setting a password for entering BIOS Setup. When a

password has been set, a password prompt will be displayed whenever BIOS

Setup is run. This prevents an unauthorized person from changing any part

of your system configuration.

There are two types of passwords you can set. A supervisor password and a

user password. When a supervisor password is used, the BIOS Setup

program can be accessed and the BIOS settings can be changed. When a

user password is used, the BIOS Setup program can be accessed but the

BIOS settings cannot be changed.

To set the password, type the password (up to eight characters in length)

and press <Enter>. The password typed now will clear any previously set

password from CMOS memory. The new password will need to be reentered

to be confirmed. To cancel the process press <Esc>.

To disable the password, press <Enter> when prompted to enter a new

password. A message will show up to confirm disabling the password. To

cancel the process press <Esc>.

Additionally, when a password is enabled, the BIOS can be set to request the

password each time the system is booted. This would prevent unauthorized

use of the system. See “Security Option” in the “Advanced BIOS Features”

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.

71

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./

72

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.
