Settings Description Auto(ESCD) BIOS will automatically assign IRQ, DMA and memory base address fields Unlocks “IRQ Resources” for manual configuration Manual PCI/VGA Palette Snoop Some non-standard VGA display cards may not show colors properly. This field allows you to set whether MPEG ISA/VESA VGA Cards can work with PCI/VGA or not.
IRQ RESOURCES IRQ Resources list IRQ 7/9/10/11/12/14/15 for users to set each IRQ a type depending on the type of device using the IRQ.

Spread Spectrum When the mainboard's clock generator pulses, the extreme values (spikes) of the pulses create EMI (Electromagnetic Interference). The Spread Spectrum function reduces the EMI generated by modulating the pulses so that the spikes of the pulses are reduced to flatter curves. Settings: [Disabled, +/- 0.1%, +/- 0.2%, +/- 0.3%, +/- 0.4%, +/- 0.5%, +/- 0.6%, +/- 0.7%, +/- 0.8%, +/- 0.
LOAD OPTIMIZED DEFAULTS This option is for restoring all the default optimized BIOS settings. The default optimized values are set by the mainboard manufacturer to provide a stable system with optimized performance. Entering “Y” and press to load the default optimized BIOS values. Entering ”N” will cancel the load optimized defaults request.
SET SUPERVISOR/USER PASSWORD Set Supervisor User Password This option is for setting a password for entering BIOS Setup. When a password has been set, a password prompt will be displayed whenever BIOS Setup is run. 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 BIOS Setup program can be accessed and the BIOS settings can be changed. When a user password is used, the BIOS Setup program can be accessed but the BIOS settings cannot be changed. To set the password, type the password (up to eight characters in length) and press . The password typed now will clear any previously set password from CMOS memory.
SAVE & EXIT SETUP Entering “Y” saves any changes made, and exits the program. Entering “N” will cancel the exit request.
EXIT WITHOUT SAVING Entering “Y’ discards any changes made and exits the program. Entering “N” will cancel the exit request.
6 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 VGA drivers. The applications will only function correctly if the necessary drivers are already installed.
DRIVER UTILITIES Getting Started The VIA EPIA-N800 includes a driver CD that contains the drivers and software for enhancing the performance of the system. The drivers can also be downloaded from http://www.via.com.tw. Note: The driver utilities and software are updated from time to time. The latest updated versions are available at http://www.via.com.tw Running the Driver Utilities CD To start using the CD, insert the CD into the CD-ROM or DVDROM drive.
CD CONTENT VIA 4 in 1 Drivers Contains VIA ATAPI Vendor Support Driver (enables the performance enhancing bus mastering functions on ATAcapable 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). Includes V-RAID and RAID tools.
