Chapter 2 Installation
K7VT4-4X / K7VT4-8X is an ATX form factor (12.0" x 7.0", 30.5 x 17.8 cm)
motherboard. Before you install the motherboard, please study the configuration of
your chassis to ensure that themotherboard fits into it.
Make sure to unplug the power cord before installing or re-
moving the motherboard. Failure to do so may cause physical
injuries to you and damages to motherboard components.
2.1 Screw Holes
Please place screws into the holes indicated by circles to secure the motherboard to
the chassis.
Do not over-tighten the screws! Doing so may damage the
motherboard.
2.2 Pre-installation Precautions
Take note of the following precautions before you install motherboard components
or change any motherboard settings.
1. Unplug the power cord from the wall socket before touching any component.
2. To avoid damaging the motherboard components due to static electricity, NEVER
place your motherboard directly on the carpet or the like. Also remember to use
a grounded wrist strap or touch a safety grounded object before you handle
components.
3. Hold components by the edges and do not touch the ICs.
4. Whenever you uninstall any component, please place it on a grounded antistatic
pad or in the bag that comes with the component.
Before you install or remove any component, pleasse ensure that the
power is switched off or the power cord is detached from the power
supply. Failure to do so may cause severe damage to the motherboard,
peripherals, and/or components.

11
2.3 CPU Installation
Step 1. Unlock the socket by lifting the lever up to a 90oangle.
Step 2. Position the CPU directly above the socket such that its marked corner
matches the base of the socket lever.
Step 3. Carefully insert the CPU into the socket until it fits in place.
The CPU fits only in one correct orientation. DO NOT force the
CPU into the socket to avoid bending of the pins.
Step 4. When the CPU is in place, press it firmly on the socket while you push
down the socket lever to secure the CPU. The lever clicks on the side tab
to indicate that it is locked.
2.4 Installation of CPU Fan and Heatsink
AMDAthlonTM / AthlonTM XP/ DuronTM family CPUs with a speed of 600 MHz and
higher require larger heatsink and cooling fan. Thermal grease between the
CPU and the heatsink is also needed to improve heat transfer. Make sure that
the CPU and the heatsink are securely fastened and in good contact with
each other. For proper installation, please kindly refer to the instruction
manuals of vendors of CPU fan and heatsink.
Step 1 Step 2, 3 Step 4

12
2.5 Installation of Memory Modules (DIMM)
K7VT4-4X / K7VT4-8X motherboard provides two 184-pin DDR (Double Data Rate)
DIMM slots.
Please make sure to disconnect power supply before adding or
removing DIMMs or the system components.
Step 1. Unlock a DIMM slot by pressing the retaining clips outward.
Step 2. Align a DIMM on the slot such that the notch on the DIMM matches the break
on the slot.
Step 3. Firmly insert the DIMM into the slot until the retaining clip snap back in place
and the DIMM is properly seated.
2.6 Expansion Slots (PCI and AGP Slots)
There are 5 PCI slots and 1 AGP slot on K7VT4-4X / K7VT4-8X motherboard.
PCI slots: PCI slots are used to install expansion cards that have the 32-bit PCI
interface.
AGP slot: The AGP slot is used to install a graphics card. The ASRock AGP slot has
a special locking mechanism which can securely fasten the graphics
card inserted.
Please do NOT insert a 3.3V AGP card into the AGP slot of
K7VT4-4X or K7VT4-8X motherboard!
It may cause permanent damage!
Installing an expansion card
Step 1. Before installing the expansion card, read the documentation of the
expansion card and make necessary hardware settings for the card.

2.7 Jumpers Setup
The illustration shows how jumpers are
setup. When the jumper cap is placed on
pins, the jumper is “SHORT”. If no jumper
cap is placed on the pins, the jumper is
“OPEN”. The illustration shows a 3-pin
jumper whose pin1 and pin2 are “SHORT”
when jumper cap is placed on these 2 pins.
Jumper Setting
FSB_SEL0
(see p.7/p.8 item 10)
Note: The setting of the CPU front side bus frequency of this motherboard is by
means of the adjustment of jumper-setting. Please follow the figures above
to set the CPU front side bus frequency.
PS2_USB_PWR1 Short pin2, pin3 to enable
(see p.7/p.8 item 1) +5VSB (standby) for PS/2 or
USB wake up events.
Note: To select +5VSB, it requires 2 Amp and higher standby current provided by
power supply.
JR1(see p.7/p.8 item 26)
JL1(see p.7/p.8 item 25)

Chapter 3 BIOS Setup
3.1 BIOS Setup Utility
This section explains how to use the BIOS Setup Utility to configure your system.
The Flash Memory on the motherboard stores the BIOS Setup Utility. You may run the
BIOS Setup when you start up the computer. Please press <F2> during the Power-
On-Self-Test (POST) to enter the BIOS Setup Utility, otherwise, POST will continue
with its test routines.
If you wish to enter the BIOS Setup after POST, restart the system by pressing
<Ctl> + <Alt> + <Delete>, or by pressing the reset button on the system chassis.
You may also restart the system by turning the system off and then back on.
The BIOS Setup Utility is designed to be user-friendly. It is a menu-driven program,
which allows you to scroll through its various sub-menus and select among the
predetermined choices.
Because the BIOS software is constantly being updated, the
following BIOS setup screens and descriptions are for reference
purpose only, and may not exactly match what you see on your
screen.

to locate and load the Operating System
EXIT Exits the current menu or the BIOS Setup
To access the menu bar items, press the right or left arrow key on the keyboard
until the desired item is highlighted.

To set the type of the IDE device, first, please select “IDE Devices” on Main
menu and press <Enter> to get into the sub-menu. Then, select among
“Primary IDE Master”, “Primary IDE Slave”, “Secondary IDE Master”, and
“Secondary IDE Slave” to make configuration of its type. Below are the
configuration options.
[USER]: It allows user to manually enter the number of cylinders, heads,
and sectors per track for the drive.
Before attempting to configure a hard disk drive, make sure you
have the correct configuration information supplied by the drive
manufacturer. Incorrect settings may cause the system to fail
to recognize the installed hard disk.
[Auto]: Select [Auto] to automatically detect hard disk drive. If auto-
detection is successful, the BIOS Setup automatically fills in the
correct values for the remaining fields on this sub-menu. If the auto-
detection fails, it may due to that the hard disk is too old or too new.
If the hard disk was already formatted on an older system, the BIOS
Setup may detect incorrect parameters. In these cases, select [User]
to manually enter the IDE hard disk drive parameters.
After entering the hard disk information into BIOS, use a disk utility,
such as FDISK, to partition and format the new IDE hard disk
drives. This is necessary so that you can write the data into or
read the data from the installed hard disk. Please make sure to set
the partition of the Primary IDE hard disk drives to make them
active.
