CONNECTING THE POWER SUPPLY

The VIA EPIA-LN Mini-ITX mainboard supports a conventional ATX power
supply for the power system. Before inser ting the power supply connector,
always make sure that all components are instal led 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.

Hard Disk Connectors: IDE1 & IDE2

The mainboard has a 32-bit Enhanced IDE and Ultra DMA 133/100/66
controller that provides PIO mode 0~4, Bus Master, and Ultra DMA
133/100/66 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 an d a slave drive .

JUMPERS

The mainboard provides jumpers for setting some mainboard functions. Th is
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 d ata 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. R eturn the jumper to p ins 1 and 2
afterwards. Setting the jumper while the system is on will damage the
mainboard.

DRAM Clock

The chipset supports synchronous and asynchronous mode between host
clock and DRAM clock frequency.

Settings: [By SPD, 100 MHz, 133 MHz, 166 MHz , 200MHz, 2 66MHz]

DRAM Timing

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 take s for the memory modu le to complete
a command. Generally, a lower setting will imp rove the performance of your
system. However, if your system becomes less stab le, you should change it
to a higher setting. This field is only available when “DRAM Timing” is set to
“Manual”.

Settings: [1.5/2, 2/3, 2.5/4, 3/5]

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 t he 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 Ba nk, 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 performan ce.
This field is only available when “D RAM Timing ” is se t to “Manua l”.

Settings: [05T, 06~20T]

This field is for setting how fast the memory controller sends out commands.
Lower setting equals faster command rate.

multiplier LOCKED!!

Key in a DEC number.
Settings: [Min = 4, Max = 50]

Spread Spectrum

When the mainboard's clock generator pulses, the extreme values (spikes ) of
the pulses creates EMI (Electromagnetic I nterference). The Spread Spectru m
function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are redu ced to fla tter curves .

Settings: [0.20%, 0.25%, 0.35%, Disabled]

Change / Set / Disable Password

: Select ItemF9 : Menu in BIOS

This option is for setting a password for entering BIOS Setup. When a
password has been set, a password prompt will b e 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 supervis or 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 pre ss <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 se t 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”
section for more details .

DRIVER UTILITIES

Getting Started

The mainboard includes a Driver Utilities CD that contains the driver utilities
and software for enhancing the perfor mance of the mainboard. If the CD is
missing from the retail box, please contact the local dea ler for th e CD.

Note: The driver utilities and software are updated from time to time. The latest

updated versions are avai labl e at ht tp:// www.viae mbedded.c om./

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 afte r clos ing the C D-ROM or DVD-RO M 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
