Insta ation
This chapter provides you with information about hardware setup
procedures. Whi e insta ing the mainboard, carefu y ho d the
components and c ose y fo ow the insta ation procedures. Some
components may be damaged if they are insta ed incorrect y.
It is recommended to use a grounded wrist strap before hand ing
computer components. Static e ectricity can damage some

CPU
The VIA EPIA-MII Mini-ITX Mainboard inc udes 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 coo ing. When connecting the
wire to the connectors, a ways be aware that the red wire is the Positive and
shou d be connected to the +12V. The b ack wire is Ground and shou d be
connected to GND. Both CPU and System fan connectors have sensors to
detect fan speed.

M EMORY M ODULE I NSTALLATION
The VIA EPIA-MII Mini-ITX Mainboard provides one 184-pin DIMM s ot for
DDR266 SDRAM memory modu es.
CLE266
DDR SDRAM Module Installation Procedures
1. Push the white retaining atches at either end of the DIMM s ot outwards.
2. A ign the DDR SDRAM modu e with the corresponding notches on the
DIMM s ot. The modu es wi on y fit if p aced in the correct position.
3. With both hands, press the DDR SDRAM modu e down into the DIMM
s ot so that the white retaining atches rotate up and secure the modu e
in p ace (see picture be ow).
