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.
Chapter 2 The VIA EPIA-NX Nano-ITX mainboard can support VIA C7 NanoBGA2 and VIA Eden NanoBGA2 processors. The processor requires a heatsink with fan for 1.5GHz SKU and a fanless heatsink for 1.2GHz SKU. CPU Fan and System Fan: CPU_FAN and SYS_FAN The CPU_FAN (CPU fan) and SYS_FAN (system fan) run on +12V and maintain system cooling.
ODULE NSTALLATION Memory Slot: DDR2_SODIMM The VIA EPIA-NX Nano-ITX mainboard provides one SODIMM slot for DDR2 533 SDRAM memory modules and supports memory sizes up to 1GB. Insert the SODIMM module at a 45 degree angle. Push the SODIMM module back towards the board until the clips lock the module in place.

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.
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.
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 78
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).
