1.4.1. Hardware Monitoring System Utility
The mainboards both come with the Hardware Monitoring System utility
contained on the CD. It is capable of monitoring the system’s hardware
conditions such as the temperature of the processor, voltage, and the speed of
both the CPU and chassis fans. You are allowed to manually set a range to the
items being monitored. If the values are over or under the set range a warning
message will automatically pop up. We recommend that you use the Default
Settings, which are the ideal settings that will maintain the system in a good
working condition.
1.4.2. Installation
To install this utility, please insert the CD into the CD-ROM drive. The auto run
screen (Driver Utility) will automatically appear. Click the Hardware Monitoring
button, choose the chipset, model number and the OS that is installed. Please
refer to the CD “Readme” file for further installation instructions.
The mainboard is capable of monitoring the following health conditions of your
system:
1. Processor temperature. It has an overheat alarm.
2. VCORE/3.3V/5V/12V/-12V voltages and failure alarm.
3. Processor and chassis fan speeds. It has a failure alarm for these fans.
4. Read back capability that displays temperature, voltage and fan speed.
1.4. System Health Monitor Functions
Note: Only use this utility in Windows ® 95 or Windows ® 98 operating systems.
Dual Function Power Button
Depending on the setting in the Soft-Off By Power-Button field of the Power
Management Setup, this switch allows the system to enter the Soft-Off or
Suspend mode.
RTC Timer to Power-on the System
The RTC installed on the system board allows your system to automatically
power-on at a set date and time.
Wake-On-LAN Ready
The Wake-On-LAN function allows the network to remotely wake up a Soft
Power Down (Soft-Off) PC. Your LAN card must support the remote wakeup
function. The 5V SB power source of your power supply must be at least
720mA.
ACPI Ready
The mainboard is designed to meet the ACPI (Advanced Configuration and
Power Interface) specification. ACPI has energy saving features that support
OS Direct Power Management (OSPM) for round the clock PC operation.

CPU Thermal Protection
This function is only for AMD Athlon XP and Duron (Morgan) processors.
1. If you haven’t installed a heat-sink with cooling FAN, or if you have installed
it incorrectly, this function will prevent the system from being turned on. If
you are unable to turn on the system check to see if the heat-sink with
cooling FAN has been installed correctly.
2. If the cooling FAN stops functioning the heat of the CPU will increase and
the system will auto power-off to protect the CPU against overheating.

2.4.2. Memory Modules
The KT33-BV mainboards have three 184-pin DDR DIMM slots and are able to
support a maximum of 3GB of DDR200/266/333 memory. The DDR DIMM
slots are located on the right hand side of the board. To install the DIMM’s into
these slots, make sure the white lever at each side of the slot has been pulled
down to an angle of approximately 45°. Make sure that the DIMM is in the
correct orientation. Place the DIMM on the slot and push down firmly.The white
levers will come back up and lock the module in place.
Important: The DIMM’s can only be fitted into the slots in one orien-
tation. Make sure that the DIMM’s are in the correct orientation and
the pins are correctly aligned before you insert them.
2.4.1. Installation of the CPU
To install your processor, please complete the following set of instructions
1. Locate a small dot marked on the top of the CPU. This mark indicates
Pin 1 of the CPU.
2. Locate Pin 1 for the Socket on the mainboard.
3. There is a lever on the side of the socket. First push this lever side-
ways and then lift it to a 90-degree angle.
4. Insert the CPU into the Socket. Please make sure that Pin 1 for the
CPU is inserted into Pin 1 of the Socket.
5. When the CPU is installed correctly push the lever back into place.
6. Install a proper heat sink with cooling fan for proper heat dissi-
pation. Failing to install a heat sink with cooling fan may cause over-
heating which will burnout your CPU and damage your mainboard.
IMPORTANT: CPU COOLING FAN
Please ensure that you have an approved heat sink with cooling fan.
Without a proper heat sink with cooling fan you will damage both the
mainboard and the CPU.

2.4.3. PCI Slots
The KT33-BV mainboards each
come with five PCI slots. They
are located on the left hand side
of the board. Both PCI and PCI
expansion cards may require
IRQ’s. This mainboard complies
with Plug and Play (PnP) specifi-
cations. Whenever a PnP compli-
ant card is added the system
will automatically be configured
and the IRQ’s will be assigned
automatically.
When you are inserting your PCI
card make sure that the pins are
correctly aligned. When the pins
are properly aligned with the
hole’s in the slot, push down
gently. 5 4 3 2 1

NOTE: “Out Of Memory” Error Message
If you have installed more than 512 MB of RAM and are running Microsoft Windows Mil-
lennium Edition, Windows 98 Second Edition, Windows 98 or Windows 95 you may ex-
perience memory problems. Two symptoms of these problems are being unable to run
an MS-DOS session while you are running Windows or the computer may stop respond-
ing while Windows is starting.
There are three possible solutions to this problem:
1) Reduce the amount of memory Vcache uses to 512 MB or less by altering the Max-
FileCache setting in the System.ini file.
2) Use the System Configuration Utility to reduce the amount of memory Windows
uses to 512 MB or less.
3) Reduce the memory installed on your computer to 512 MB or less.
This problem can also occur if an Advanced Graphic Port (AGP) video adapter is used.

2.5.1. Floppy Disk Connector
(FDC)
Connector: CN 8
Type: 34 pin block
The FDC connector can support two
Floppy drives. It is located at the
front of the mainboard. To connect,
use the ribbon-cable that has been
provided. Make sure that the red
strip is connected to PIN 1 of the
connector.
2.5.2. Primary and Secondary
IDE connectors
Connector:
CN 9 (primary)/ CN 10 (secondary)
Type: 40 pin blocks
The KT33-BV mainboards have two
IDE connectors: a primary and sec-
ondary. Each IDE connector can sup-
port two IDE drives. These main-
boards can therefore support up to
four IDE devices each. If you install
two hard drives, you need to config-
ure the second drive to slave mode
in the BIOS setup. Please refer to
your hard drive manual for the ap-
propriate jumper settings.

2.5.7. USB 3 and USB 4 connectors
Connector: CN 30 /CN 31
Type: 10 pin
You already have two USB ports available, USB 1 and 2 (see external connec-
tors). The internal USB connectors allow you to add on an optional kit to ex-
pand the total number of USB ports available. The KT33-BV mainboards has
two internal USB connectors (CN30 and CN31). This enables you to use an
extra two USB devices. Cable for these additional connectors needs to be pur-
chased separately.
2.5.6. CD-IN/AUX-IN Connector
Connector: CN 21 (CD-IN/ CN 45 (AUX-IN)
Type: 4 pin un-housed
The KT33-BV mainboards have one CD-IN connector and one AUX-IN connec-
tor . The CD-IN connector is used to connect the CD ROM audio out and al-
lows the system to receive audio input from the CD ROM. The AUX-IN con-
nector allows the system to receive signals from other audio devices like a ra-
dio or tape.

2.5.8. Front Audio Connector
Connector: CN 39
Type: 10 pin
The front audio connector is an innovative development. This connector is designed to be
used with a Front-Utility Panel. The utility panel was developed so that a user is able to
bring the speaker out, microphone in connectors to the front of their PC. This makes
things like plugging in speakers and earphones much less troublesome. See the diagram
on the following page.
