NSTALLATION

This chapter provides you 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.

6

CPU

The VIA NAB-7500 mainboard is packaged with a standard VIA C7 ®

1.5GHz NanoBGA2 processor. Other processor speeds (i.e., 2.0GHz and

1.0GHz) are also available as manufacturing options. The VIA C7 cooling.

®

1.5GHz processor requires a heatsink with fan to provide sufficient

CPU Fan and System Fan: CPUFAN and SYSFAN

The CPU_FAN (CPU fan) and SYS_FAN (system fan) run on +12V and maintain system cooling. When connecting the wire to the connectors, always be aware that the red wire (positive wire) should be connected to the +12V. The black wire is Ground and should always be connected to

GND.

Memory Module Installation

Memory Slot: DDR2 DIMM

The VIA NAB-7500 mainboard provides two 240-DIMM slots for DDR2

667/533 SDRAM memory modules and supports memory sizes up to

3.5GB.

DDR2 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.

Connecting the Power Supply

The VIA NAB-7500 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 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.

Jumpers

The mainboard provides jumpers for setting some mainboard functions.

This section will explain how to change the settings of the mainboard functions using the jumpers.

Clear CMOS Connector: CLEAR_CMOS

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 1 and 2 while the system is off. Return the jumper to pins 2 and 3 afterwards. Setting the jumper while the system is on will damage the mainboard.

Normal Operation ON ON OFF

Clear CMOS setting OFF ON ON

Warning:

Except when clearing the RTC RAM, never remove the cap on

CLEAR_CMOS jumper default position. Removing the cap will cause system boot failure. Avoid clearing the CMOS while the system is on; it will damage the mainboard.

Master/Slave Setting for CF Connector: MS_CF_SEL

This jumper determines the working state of the CF connector. The default value is Master.

The PC Health Status displays the current status of all of the monitored hardware devices/components such as CPU voltages, temperatures and fan speeds.

53

Frequency/Voltage Control

DRAM Clock

The chipset supports synchronous and asynchronous mode between host clock and DRAM clock frequency.

Settings: [By SPD, 200MHz, 266MHz, 333MHz]

DRAM Timing

The value in this field depends on the memory modules installed in your system. Changing the value from the factory setting is not recommended unless you install new memory that has a different performance rating than the original modules.

Settings: [Manual, Auto By SPD]

Auto Detect PCI Clk

Settings: [Enabled, Disabled]

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, Enabled]

54

Load Fail-Safe Defaults

This option is for restoring all the default fail-safe BIOS settings. These values are set by the mainboard manufacturer to provide a stable system with basic performance. Entering “Y” and press <Enter> to load the default fail-safe BIOS values. Entering “N” and press <Enter> will cancel the load fail-safe defaults request.

55

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 <Enter> to load the default optimized BIOS values. Entering ”N” will cancel the load optimized defaults request.

56

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.

57

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 <Enter>. The password typed now will clear any previously set password from CMOS memory. The new password will need to be reentered to be confirmed. To cancel the process press <Esc>.

To disable the password, press <Enter> when prompted to enter a new password. A message will show up to confirm disabling the password.

To cancel the process press <Esc>.

Additionally, when a password is enabled, the BIOS can be set to request the password each time the system is booted. This would prevent unauthorized use of the system. See “Security Option” in the

“Advanced BIOS Features” section for more details.

58

Save & Exit Setup

Entering “Y” saves any changes made, and exits the program.

Entering “N” will cancel the exit request.

59

Exit Without Saving

Entering “Y’ discards any changes made, and exits the program.

Entering “N” will cancel the exit request.

NSTALLATION

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.

61

Driver Utilities

Getting Started

VIA NAB-7500 Developer kits include a Driver CD that contains the drivers and software for enhancing the performance of the mainboard.

Regular kits do not include a Driver CD. However, the latest drivers can 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

62

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. If the CD does not run automatically, click on the “Start” button and select “Run…” Then type: "D:\Setup.exe".

For Linux drivers, click the right button on mouse and click open. Linux drivers are located in the "Driver" folder.

Note:

D: might not be the drive letter of the CD-ROM/DVD-ROM in your system.
