Hardware Setup
Installation
This chapter provides you with the information about hardware setup procedures. While installing, be careful in
holding the components and follow the installation
procedures. Some components can be damaged if installed
incorrectly. If possible, use a grounded wrist strap before
handling computer components. The components can be
damaged by static electricity.

CPU
The VIA EPIA-M Mini-ITX Mainboard includes an embedded VIA Eden Processor or VIA C3™ 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 sensor. FAN3 is an additional FAN connector.

Memory Installation
The VIA EPIA-M Mini-ITX Mainboard provides one 184-pin DIMM slot for
DDR266 SDRAM memory modules.
DIMM
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).

Power Supply
The VIA EPIA-M 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.
A TX 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.

Line-Out is a connector for speakers
or headphones. The Line-In connec-
tor can be used for an external CD
player, tape player, or other audio
devices. The Mic-In connector is for
connecting microphones. Please note
when 6-channel applications are used,
all three connectors become output
connectors. Line-Out becomes Front
L/R; Line-In becomes Rear L/R; Mic-
In becomes Center/Sub. Note:
Win98SE supports only 4-CH output.
