Specifications

The ultra-compact and highly intergrated VIA
EPIA-ML Mini-ITX Mainboard is the smallest
form factor mainboard specification available
today, developed by VIA Technologies, Inc. as part
of the company’s open industry-wide total
connectivity initiative. The mainboard enables the
creation of an exciting new generation of small,
ergonomic, innovative and affordable embedded
systems. Through high level of integration, mini­ITX only occupy 66% of the size of FlexATX
mainboard form factor. The mainboard comes with

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

TM

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 a sensor.
FAN3 is an additional FAN connector.

Hard Disk Connectors: IDE1 & IDE2

The mainboard has a 32-bit Enhanced PCI IDE and Ultra DMA 33/66/100/
133 controller that provides PIO mode 0~4, Bus Master, and Ultra DMA 33/
66/100/133 functions. You can connect up to four hard disk drive, CD­ROM, LS-120 and other devices. These connectors utilize the provided IDE
hard disk cable.

IDE 1

IDE 2

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.

Jumpers

The mainboard provides jumpers for setting the mainboard’s functions. This
section will explain how to change settings for your 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.

Slots

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:

Order 1 Order 2 Order 3 Order 4

PCI Slot INT B# INT C# INT D# INT A#

Type the password, up to eight characters in length, and press Enter. The
password typed now will clear any previously set password from CMOS
memory. You will be prompted to confirm the password. Re-type the
password and press Enter. You may also press Esc to abort the selection
and not enter a password.

To clear a set password, just press Enter when you are prompted to enter
the password. A message will show up confirming the password will be
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
User password. When a Supervisor password is used, the user can start
BIOS Setup program and change the settings of the setup menus. When a
User password is used, the user can start the BIOS Setup program but does
not have the right to change the settings of the setup menus.

Additionally, when a password is enabled, you can also have BIOS to
request a password each time the system is booted. This would prevent
unauthorized use of your computer. The setting to determine when the
password prompt is required is the Security Option of the Advanced BIOS
Features menu. If the Security Option is set to
required both at boot and at entry to Setup. If set to

System, the password is

Setup, password prompt

only occurs when trying to enter Setup.
