HAPTER Installation This chapter provides with information about hardware installation procedures. It is recommended to use a grounded wrist strap before handling computer components. Electrostatic discharge (ESD) can damage some components.
Page 18: Cpu
Chapter 2 The VIA EPIA-EN Mini-ITX mainboard includes an embedded VIA C7 or Eden V4 Bus Processor. The VIA Eden V4 Bus Processor provides ultra-low power consumption and advanced thermal dissipation properties and features a fanless design. The VIA C7 or Eden V4 Bus Processor requires only a heatsink to provide sufficient cooling.
Page 19 Installation CPU Fan and System Fan: CPUFAN and SYSFAN 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 always be connected to GND.
Page 20: Memory Module Installation
Chapter 2 EMORY ODULE NSTALLATION The VIA EPIA-EN Mini-ITX mainboard provides one 240-pin DIMM slot for DDR2 533/400 SDRAM memory modules and supports the memory size up to 1GB. DIMM DDR SDRAM Module Installation Procedures Locate the DIMM slot in the motherboard. Unlock a DIMM slot by pressing the retaining clips outward.

HAPTER Driver Installation This chapter gives you brief descriptions of each mainboard driver and application. You must install the VIA chipset drivers first before installing other drivers such as audio or VGA drivers. The applications will only function correctly if the necessary drivers are already installed.
Page 84: Driver Utilities
Chapter 4 RIVER TILITIES Getting Started The mainboard includes a Driver Utilities CD that contains the driver utilities and software for enhancing the performance of the mainboard. 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.
Page 85 Driver Installation Running the Driver Utilities CD To start using the CD, insert the CD into the CD-ROM or DVD-ROM drive. The CD should run automatically after closing the CD-ROM or DVD-ROM drive. The driver utilities and software menu screen should then appear on the screen.
Page 86: Cd Content
Chapter 4 CD C ONTENT VIA 4in1 Drivers: Contains VIA ATAPI Vendor Support Driver (enables the performance enhancing bus mastering functions on ATA-capable Hard Disk Drives and ensures IDE device compatibility), AGP VxD Driver (provides service routines to your VGA driver and interface directly to hardware, providing fast graphical access), IRQ Routing Miniport Driver (sets the system's PCI IRQ routing sequence) and VIA INF Driver (enables the VIA Power Management function).
