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-CL 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. The CPU, System and Power fan connectors have sensors
to detect fan speed.

Hard Disk Connectors: IDE1 & IDE2
The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 66/100/133
controller that provides PIO mode 0~4, Bus Master, and Ultra DMA
66/100/133 functions. You can connect up to four hard disk drive, CD-ROM,
LS-120 and other devices. These connectors utilize the provided IDE hard
disk cable.
IDE1 (Primary IDE Connector)
The first hard drive should always be connected to IDE1. IDE1 can connect a
Master and a Slave drive. You must configure the second hard drive to Slave
mode by setting the jumper accordingly.
IDE2 (Secondary IDE Connector)
IDE2 can also connect a Master and a Slave drive.
If you install two hard disks on a single cable, you must set the jumper on
the second hard disk drive to slave mode. Please refer to the hard disk
documentation supplied by hard disk vendor for the jumper settings.

UMPERS
The mainboard provides jumpers for setting some mainboard functions. This
section will explain how to change settings of the mainboard’s functions
through the use of the jumpers.
Clear CMOS: CLEAR_CMOS
The onboard CMOS RAM stores system configuration data and has an
onboard battery power supply. The long-life battery has a lifetime of at least
5 years. If you want to clear the system configuration data from the CMOS
RAM, use the CLEAR_CMOS (Clear CMOS jumper). You can clear the CMOS by
shorting 1-2 pin while the system is off. Then return it to the 2-3 pin position.
Shorting the jumper while the system is on will damage the mainboard.

Peripheral Component Interconnect: PCI
The PCI slot allows you to insert PCI expansion card. When adding or
removing expansion cards, make sure that you unplug the power supply first.
Meanwhile, read the documentation for the expansion card to make any
necessary hardware or software settings for the expansion card, such as
jumpers, switches or BIOS configuration.
PCI Interrupt Request Routing
The IRQ, abbreviation of interrupt request line and pronounced I-R-Q, are
hardware lines over which devices can send interrupt signals to the
microprocessor. The “PCI & LAN” IRQ pins are typically connected to the PCI
bus INT A# ~ INT D# pins as follows:

not enter a password.
To clear a set password, just press Enter when you are prompted to enter

disabled. Once the password is disabled, the system will boot and you can
enter Setup without entering any password.
When a password has been set, you will be prompted to enter it every time
you try to enter Setup. 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

Getting Started
The mainboard includes a Driver Utilities CD which contains the driver utilities
and software for enhancing the performance of the mainboard. Please check
that you have this CD in your retail box. If the CD is missing from the retail
box, please contact the local dealer for the CD.
Note:
The driver utilities and software are updated from time to time. Please
visit our website (http://www.viaembedded.com/) for the latest updated
