DDR SDRAM Module Installation Procedures

• Locate the DIMM slot in the motherboard.

• Unlock a DIMM slot by pressing the retaining clips outward.

• Align a DIMM on the socket such that the notch on the DIMM

matches the break on the slot.

• Firmly insert the DIMM into the slot until the retaining clips snap

back in place and the DIMM is properly seated.

Available DDR SDRAM Configurations

Refer to the table below for available DDR SDRAM configurations on the

mainboard.

Slot Module Size Total

DIMM 64MB, 128MB, 256MB, 512MB, 1GB 64MB-1GB

ONNECTING THE POWER SUPPLY

The VIA EPIA-LT Mini-ITX mainboard supports a conventional ATX power

supply for the power system. 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 power plug is inserted in

the proper orientation and the pins are aligned. Then push down the plug

firmly into the connector.

or headphones. The Line-In jack is for connecting to

an external audio device such as a CD player, tape

player, etc. The Mic jack is for connecting to a

microphone.

Note:

The audio ports can be switched to Smart 5.1 6-channel audio output.
You can enable the function by clicking the “Vinyl Audio” icon on your
desktop after installing the audio driver.

After completing the previous installation, connect the speakers to the 3-jack

ONNECTORS

Hard Disk Connectors: IDE1

The mainboard has a 32-bit Enhanced IDE and Ultra DMA 133/100/66

controller that provides PIO mode 0~4, Bus Master, and Ultra DMA

133/100/66 functions. You can connect up to four hard disk drives, CD-ROM

and other devices.

Serial ATA Connectors: SATA1 and SATA2

These next generation connectors support the thin Serial ATA

cables for primary internal storage devices. The current Serial

ATA interface allows up to 150MB/s data transfer rate, faster

than the standard parallel ATA with 133 MB/s (Ultra DMA).

USB Pin Connector: USB

The mainboard provides one USB pin header, allowing up to 2 additional

USB2.0 ports up to maximum throughput of 480 Mbps. Connect each 2-port

USB cable into this pin header. This port can be used to connect high-speed

USB interface peripherals such as USB HDD, digital cameras, MP3 players,

printers, modem and the like.

The reset switch is used to reboot the system rather than turning the power

ON/OFF. Avoid rebooting the system, if the HDD is still working. Connect

the reset switch from the system case to this pin.

Power LED (-PLED)

The LED will light when the system is on. If the system is in S1 (POS - Power

On Suspend) or S3 (STR - Suspend To RAM) state, the LED will blink.

HDD LED (HD_LED)

HDD LED shows the activity of a hard disk drive. Avoid turning the power off

when the HDD LED still has a lit. Connect the HDD LED from the system case

to this pin.

The onboard CMOS RAM stores system configuration data and has an

onboard battery power supply. To reset the CMOS settings, set the jumper

on pins 2 and 3 while the system is off. Return the jumper to pins 1 and 2

afterwards. Setting the jumper while the system is on will damage the

mainboard.
