Installation
This chapter provides you with information about
hardware setup procedures. While installing the
mainboard, carefully hold the components and
closely follow the installation procedures. Some
components may be damaged if they are installed
incorrectly.
It is recommended to use a grounded wrist strap
before handling computer components. Static
electricity can damage some components.

CPU
The VIA EPIA-ML Mini-ITX Mainboard includes an embedded VIA Eden
Processor or VIA C3TM E-Series Processor. 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 be connected to GND. Both CPU and System fan connectors
have sensors to detect fan speed, but the power fan does not have a sensor.
FAN3 is an additional FAN connector.
The VIA C3TM E-Series Processor
With low power consumption and advanced
thermal dissipation properties, the embedded
VIA C3TM E-Series requires only a small fan
to guarantee performance and reliability.
Ensure that the CPU Fan Connector is
correctly installed as shown.

The VIA Eden Processor
Providing ultra-low power consumption and
advanced thermal dissipation properties, the
VIA Eden Processor features a fanless design.
The VIA Eden Processor requires only a
heatsink as shown.
Warning: This motherboard is not designed to support overclocking. Any attempt to
operate beyond product specifications is not recommended. We do not guarantee
the damages or risks caused by operation beyond product specifications.

Memory Module Installation
The VIA EPIA-ML Mini-ITX Mainboard provides one 184-pin DIMM slot
for DDR266 SDRAM memory modules.
DDR SDRAM Module Installation Procedures
1. Push the white retaining latches at either end of the DIMM slot outwards.
2. Align the DDR SDRAM module with the corresponding notches on the
DIMM slot. The modules will only fit if placed in the correct position.
3. With both hands, press the DDR SDRAM module down into the DIMM
slot so that the white retaining latches rotate up and secure the module in
place (see picture below).

Connecting the Power Supply
The VIA EPIA-ML Mini-ITX Mainboard requires an ATX power supply to
be connected. 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 plugs of the power supply
are inserted in the proper orientation and the pins are correctly aligned.
Then, push down the power supply plug firmly into the connector.
