2. Installation
K7VT4A+ is an ATX form factor (12.0-in x 7.0-in, 30.5 cm x 17.8 cm) motherboard.
Before you install the motherboard, study the configuration of your chassis to en-
sure that the motherboard fits into it.
Pre-installation Precautions
Take note of the following precautions before you install motherboard
components or change any motherboard settings.
Before you install or remove any component, 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.
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, place it on a grounded anti-
static pad or in the bag that comes with the component.
5. When placing screws into the screw holes to secure the motherboard
to the chassis, please do not over-tighten the screws! Doing so may
damage the motherboard.

10
2.1 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.
2.2 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. Then connect the CPU fan to the CPU_FANconnector (CPU_FAN1,
see page 7, No. 2). For proper installation, please kindly refer to the instruc-
tion manuals of the CPU fan and heatsink vendors.
Step 1 Step 2, 3 Step 4

11
2.3 Installation of Memory Modules (DIMM)
K7VT4A+ motherboard provides two 184-pinDDR (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 aDIMM on the slot such that the notch on theDIMM matches the break
on the slot.
The DIMM only fits in one correct orientation. It will cause permanent
damage to the motherboard and the DIMM if you force the DIMM into
the slot at incorrect orientation.
Step 3. Firmly insert theDIMM into the slot until the retaining clips at both ends fully
snap back in place and the DIMM is properly seated.

a special design of clasp that can securely fasten the inserted graphics
card.
Please doNOT use a 3.3VAGP card on theAGP slot of this motherboard!
It may cause permanent damage! For the voltage information of your
graphics card, please check with the graphics card vendors.
Installing an expansion card
Step 1. Before installing the expansion card, please make sure that the power
supply is switched off or the power cord is unplugged. Please read the
documentation of the expansion card and make necessary hardware
settings for the card before you start the installation.
Step 2. Remove the system unit cover (if your motherboard is already installed
in a chassis).
Step 3. Remove the bracket facing the slot that you intend to use.
Keep the screws for later use.
Step 4. Align the card connector with the slot and press firmly until the card is
completely seated on the slot.
Step 5. Fasten the card to the chassis with screws.
Step 6. Replace the system cover.

Note: To select +5VSB, it requires 2 Amp and higher standby current provided by power
supply.
JR1 / JL1 Jumpers
(seep.7item 23)
Note: If JR1 and JL1 Jumpers are short, both the front panel and the rear panel audio
connectors can work.
Clear CMOS Jumper
(CLRCMOS2)
(seep.7item 19)
Note: CLRCMOS2 allows you to clear the data in CMOS. The data in CMOS includes system
setup information such as system password, date, time, and system setup parameters. To
clear and reset the system parameters to default setup, please turn off the computer and
unplug the power cord from the power supply. After waiting for 15 seconds, use a jumper

TYPE
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.
