CPU Fan:
The CPU fan runs on +12V and maintains the system cooling. When
connecting the wire to the connectors, always be aware that the red wire
should be connected to the +12V. The black wire should be connected to
GND.

MEMORY MODULE INSTALLATION
The VIA EPIA-N Nano-ITX mainboard provides one 200-pin SODIMM slot for
DDR266/333/400 SDRAM memory modules.
DDR SDRAM Module Installation Procedures
• Make sure the notch is on the proper side.
• Insert the memory module into the slot at a
30 degree angle (30 degrees from the
board). It should lightly snap into place.
• Push the module up against the board and
release your finger when the clips lock the
module.
Available DDR SDRAM Configurations
Refer to the table below for available DDR SDRAM configurations on the
mainboard.

CONNECTING THE POWER SUPPLY
The VIA EPIA-N Nano-ITX mainboard requires a special power cable adapter
to connect to a conventional ATX power supply. Before inserting the power
supply connector, always make sure that all components are installed
correctly to ensure that no damage will be caused.
Nano-ITX 12-Pin Power Connector
To connect the ATX power supply, make sure the power cable pins are
properly aligned. Then insert the plug firmly into the connector.

CONNECTORS
Hard Disk Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced IDE and Ultra DMA 66/100/133
controller that provides PIO mode 0~4, Bus Master, and Ultra DMA
66/100/133 functions. Up to four IDE devices can be connected to the
system.
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.
IDE1
1
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.
The mainboard has include IDE2 as 44-pin IDE connector for installing a mini
2.5 inches 44-pin IDE hard drive.

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 1 and 2 while the system is off. Return the jumper to pins 2 and 3
afterwards. Setting the jumper while the system is on will damage the
mainboard.

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 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”
section for more details.
