400/533 SDRAM memory modules and supports th e memory size up to 1GB.
DIMM
DDR2 SDRAM Module Installation Procedures
• Locate the DIMM slot in the motherboard.
• Unlock a DIMM slot by pressing the retain ing clips ou tward.
• 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-7400 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 supp ly, 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.
The 9-pin COM 1 port is for pointing devices or other
serial devices.
USB 2.0 ports
The USB ports is for connecting to extern al periphera l
devices.
Installation
RJ-45 10/100 LAN ports
The mainboard provides four standard RJ-45
ports which allow connection to a Local Area
Network (LAN).

CONNECTORS
Hard Disk Connectors: IDE1 & IDE2
The mainboard has an Ultra DMA 133/100/66 controller. You can connect up
to four hard disk drives, CD-ROM and other dev ices.
The primary hard drive should always be connected to IDE1 as the master
drive. Both IDE drives can connect to a master an d a slave drive .
IDE1 (40 pins)

If two drives are connected to a single ca ble, the jumper on the secon d drive
must be set to slave mode. Refer to the d rive documentation supplied by the
vendor for the jumper settings.
HDD LED shows the activity of a hard disk drive. Avoid turn ing the power off
when the HDD LED still has a lit. Connect the HDD LED from the system case
to this pin.
Power Switch (PW_BN): pin 6 & pin 8
Connect to a 2-pin power button switch. Pressing this button will turn the
system power on or off.
Reset Switch (RST_SW): pin 10 & pin 12
The reset switch is used to rebo ot 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.
Sleep LED (-SLEEP_LED): pin 14 and pin 16
Power LED (-PLED_2): pin 1 & pin 5, or pin 3 & pin 5
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 b link.
Speaker (SPEAK): pin 7 & pin 13
The speaker from the system case is connected to this pin.

USB Pin Connector: USB 2-4
The mainboard provides 3 front USB pin headers, allowing up to 6 additional
USB 2.0 ports up to maximum throughput of 480 Mbps. Connect each 2-port
USB cable into the 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 mainboard provides jumpers for setting some mainboard functions. Th is
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 d ata 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. R eturn the jumper to p ins 2 and 3
afterwards. Setting the jumper while the system is on will damage the
mainboard.

CPU Clock Ratio
To configure the CPU internal clock multiplier. This option does NOT apply to
CPU(s) which have this clock multiplier locked.
Settings: [Key in a DEC number ranged be tween 8~50]
Spread Spectrum
When the mainboard's clock generator pulses, the extreme values (spikes ) of
the pulses creates EMI (Electromagnetic I nterference). The Spread Spectru m
function reduces the EMI generated by modulating the pulses so that the
spikes of the pulses are redu ced to fla tter curves .

This option is for setting a password for entering BIOS Setup. When a
password has been set, a password prompt will b e 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 supervis or 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 pre ss <Esc>.

Chapter 3
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 se t 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 .

Driver Installation
This chapter gives you brief descriptions of ea ch mainboard dr iver and
application. You must install the VIA chipset drivers first before
installing other drivers such as audio or VGA drive rs. The applications
will only function correctly if the necessary drivers are already
installed.

DRIVER UTILITIES
Getting Started
The Driver Utilities CD contains the driver utilities and software for enhancing
the performance of the mainboard.
Note: The driver utilities and software are updated from time to time. The
latest updated versions are avai lable at http:// www. viaem bedde d.com. /

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 afte r clos ing the C D-ROM or DVD-RO M 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".
Note: D: might not be the drive letter of the CD-ROM/DVD-ROM in
your system.

Watchdog Timer Configuration
The WDT is used to generate a varie ty of output signals after a user
programmable count. The WDT is suitable for use in the prevention
of system lock-up, such as when software becomes trapped in a
deadlock. Under these sort of circumstances, the timer w ill count to
zero and the selected outputs will be driven. Under normal
circumstance, the user will restart the WDT at reg ular intervals before
the timer counts to zero.
