CPU

The VIA EPIA-CL Mini-ITX Mainboard includes an embedded VIA Eden

Processor or VIA C3 TM 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.

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 motherboard is not designed to support overclocking. Any attempt to operate beyond product specifications is not recommended. We do not guarantee the damages or risks caused by operation beyond product specifications.

Memory Module Installation

The VIA EPIA-CL Mini-ITX Mainboard provides one DIMM slot for

DDR266 memory modules.

CLE266

DDR Module Installation Procedures

1. Push the white retaining latches at either end of the DIMM slot outwards.

2. Align the DDR 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 module down into the DIMM slot so that the white retaining latches rotate up and secure the module in place

(see picture below).

Connecting the Power Supply

The VIA EPIA-CL 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.

ATX 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.

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.

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.

CLE266

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

S1 & S3

S1/Power On Suspend (POS) is a low power state. In this state, no system context (CPU or chipset) is lost and hardware maintains all system context.

S3/Suspend To RAM (STR) is a power-down state. In this state, power is supplied only to essential components such as main memory and wakeupcapable devices. The system context is saved to main memory, and context is restored from the memory when a “wakeup” event occurs.

Depends on OS to select S1 or S3.

DRAM CAS Latency

This item adjusts the speed it takes for the memory module to complete a command. Generally, a lower setting will improve the performance of your system. However, if your system becomes less stable, you should change it to a higher setting. This field is only available when DRAM Timing is set to

Manual. Settings: 2, 2.5

Chapter 3

Bank Interleave

Set the interleave mode of the SDRAM interface. Interleaving allows banks of SDRAM to alternate their refresh and access cycles. One bank will undergo its refresh cycle while another is being accessed. This improves performance of the SDRAM by masking the refresh time of each bank. This field is only available when DRAM Timing is set to Manual. Settings:

Disabled, 2 Bank , 4 Bank

Precharge to Active (Trp)

This field controls the length of time it takes to precharge a row in the memory module before the row becomes active. Longer values are safer but may not offer the best performance. This field is only available when DRAM

Timing is set to Manual. Settings: 2T, 3T

Active to Precharge (Tras)

This field controls the length of time it a row stays active before precharging.

Longer values are safer buy may not offer the best performance. This field is only available when DRAM Timing is set to Manual. Settings: 5T, 6T

Active to CMD (Trcd)

This field is only available when DRAM Timing is set to Manual. Settings:

Set Supervisor / User Password

When you select this function, a message as below will appear on the screen:

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.

3-32

BIOS Setup

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 System , the password is required both at boot and at entry to Setup. If set to Setup , password prompt only occurs when trying to enter Setup.
