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.

Chapter 2
CPU
The VIA C3 E-Series Processor
The VIA EPIA-SP Mini-ITX mainboard includes an embedded VIA C3 or Eden
Processor. The VIA C3 Processor provides ultra-low power consumption and
advanced thermal dissipation properties. The VIA C3 Processor requires
heatsink and a CPU fan to provide sufficient cooling. Ensure that the CPU
fan is correctly installed as shown.
10
Installation
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 mainboard is not designed to support overclocking.
Any attempt to operate beyond product specifications is not
recommended. We do not guarantee the damage or risks caused by
inadequate operation or beyond product specifications.
11
Chapter 2
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. The CPU
system and power fan connectors have sensors to support fan monitoring
except for +12V_CONN.

CONNECTING THE POWER SUPPLY
The VIA EPIA-SP 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.

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. Both IDE1 and IDE2 have a 20th pin
included. The 20th pin was added to provide extra voltage to power 40-pin
Disk-on Modules (DOM). See voltage selector: J1 on page 38 and 40. You
must use IDE cables that do not block the 20th pin.

Note:
If you don’t want to connect to the front audio header, pins 5 & 6, 9 &
10 have to be jumpered in order to have signal output directed to the
rear audio ports. Otherwise, the Line-Out connector on the back
panel will not function.

LVDS Connector:
This connector is for devices requiring display interface such as LVDS, and
TTL. The LVDS connector may not be available on your mainboard. This is
an option that is added during the manufacturing process. If you would like
a mainboard with the LVDS connector, please contact your vendor or sales
contact for more information.

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

Installation
Clear CMOS: CLEAR_CMOS
This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS.
You can clear the CMOS memory of date, time and system setup parameters
by erasing the CMOS RTC RAM data. The onboard
1
1
button cell battery powers the RAM data in CMOS
that include system setup information such as
system passwords.
1-2: Normal (Default)
2-3: Clear CMOS
To erase the RTC RAM:
1.
Turn OFF the computer and unplug the power cord.
2.
Remove the onboard battery
3.
Move the jumper cap from pins 1-2 (default) to pins 2-3. Keep cap
on pins 2-3 for about 5~10 seconds, then move the cap back to pins
1-2.
4.
Replace the battery.
5.
Plug the power cord and turn ON the computer.
6.
Hold down the <Del> key during the boot process and enter BIOS
setup to re-enter data.
WARNING: Except when clearing the RTC RAM, never remove the
cap on CLEAR_CMOS jumper default position. Removing the cap
will cause system boot failure. Avoid clearing the CMOS while the
system is on; it will damage the mainboard.
