PC Alert™ 4

The PC Alert TM 4 is a utility you can find in the CD-ROM disk. The utility is just like your PC doctor that can detect the following PC hardware status during real time operation:

Ø monitor CPU & system temperatures

Ø monitor fan speeds

Ø monitor system voltages

If one of the items above is abnormal, the program main screen will be immediately shown on the screen, with the abnormal item highlighted in red.

This will continue to be shown until the condition returns to the normal status.

Users can use the Adjusting Keys to change the minimum and maximum threshold of each item for the system to send out a warning message. Click Temperature to select the temperature modes of either Fahrenheit ( o F) or Celsius ( o C). The PC

Alert™ 4 icon on the Status Area will show the current CPU temperature.

MSI Reminds You...

1. Items shown on PC Alert 4 vary depending on your system status.

2. Whenever the minimum or maximum threshold of each item has been changed, please close the PC Alert 4 program for the new settings to take effect.

Hardware Setup

Central Processing Unit: CPU

The mainboard supports Intel ® Pentium ® 4 processors in the 478 pin package. The mainboard uses a CPU socket called PGA478 for easy CPU installation. When you are installing the CPU, make sure the CPU has a heat sink and a cooling fan attached on the top to prevent overheating.

If you do not find the heat sink and cooling fan, contact your dealer to purchase and install them before turning on the computer.

Overheating

Overheating will seriously damage the CPU and system, always make sure the cooling fan can work properly to protect the CPU from overheating.

Replacing the CPU

While replacing the CPU, always turn off the ATX power supply or unplug the power supply’s power cord from grounded outlet first to ensure the safety of CPU.

Overclocking

This motherboard is designed to support overclocking.

However, please make sure your components are able to tolerate such abnormal setting, while doing overclocking. Any attempt to operate beyond product specifications is not recommended. We do not guarantee the damages or risks caused by inadequate operation or beyond product specifications.

CPU Installation Procedures for Socket 478

1. Please turn off the power and unplug the power cord before installing the CPU.

2. Pull the lever sideways away from the socket. Make sure to raise the lever up to a 90-degree angle.

3. Look for the gold arrow. The gold arrow should point towards the lever pivot. The

CPU can only fit in the correct orientation.

4. If the CPU is correctly installed, the pins should be completely embedded into the socket and can not be seen.

Please note that any violation of the correct installation procedures may cause permanent damages to your mainboard.

5. Press the CPU down firmly into the socket and close the lever. As the CPU is likely to move while the lever is being closed, always close the lever with your fingers pressing tightly on top of the CPU to make sure the CPU is properly and completely embedded into the socket.

Installing the CPU Fan

As processor technology pushes to faster speeds and higher performance, thermal management becomes increasingly important. To dissipate heat, you need to attach the CPU cooling fan and heatsink on top of the CPU. Follow the instructions below to install the Heatsink/Fan:

1.

Locate the CPU and its retention mechanism on the motherboard.

2.

Position the heatsink onto the retention mechanism.

3.

Mount the fan on top of the heatsink.

Press down the fan until its four clips get wedged in the holes of the retention mechanism.

4.

Press the two levers down to fasten the fan. Each lever can be pressed down in only ONE direction.

Connectors

The mainboard provides connectors to connect to FDD, IDE HDD, case, audio, LAN, USB Ports, and CPU/System fans.

Floppy Disk Drive Connector: FDD1

The mainboard provides a standard floppy disk drive connector that supports 360K, 720K, 1.2M, 1.44M and 2.88M floppy disk types.

Fan Power Connectors: CFAN1/SFAN1

The CFAN1 (processor fan) & SFAN1 (system fan) support system cooling fan with +12V. It supports three-pin head connector. When connecting the wire to the connectors, always take note that the red wire is the positive and should be connected to the +12V, the black wire is Ground and should be connected to GND. If the mainboard has a System Hardware Monitor chipset on-board, you must use a specially designed fan with speed sensor to take advantage of the CPU fan control.

MSI Reminds You...

If you don’t want to connect to the front audio header, pins 5 & 6, 9 & 10 have to be jumpered in order to have signal output directed to the rear audio ports. Otherwise, the Line-Out connector on the back panel will not function.

Front USB Connector: JUSB1

The mainboard provides one USB 2.0 pin header JUSB1 (optional USB

2.0 bracket available) that is compliant with Intel ® I/O Connectivity Design

Guide. USB 2.0 technology increases data transfer rate up to a maximum throughput of 480Mbps, which is 40 times faster than USB 1.1, and is ideal for connecting high-speed USB interface peripherals such as USB HDD , digital cameras , MP3 players , printers , modems and the like .

Jumpers

The motherboard provides the following jumpers for you to set the computer’s function. This section will explain how to change your motherboard’s function through the use of jumpers.

Clear CMOS Jumper: JBAT1

There is a CMOS RAM on board that has a power supply from external battery to keep the data of system configuration. With the CMOS RAM, the system can automatically boot OS every time it is turned on. If you want to clear the system configuration, use the JBAT1 (Clear CMOS Jumper ) to clear data.

MSI Reminds You...

You can clear CMOS by shorting 2-3 pin while the system is off.

Then return to 1-2 pin position. Avoid clearing the CMOS while the system is on; it will damage the mainboard.

Hardware Setup

CPU Support Jumper: JP1

This jumper specifies the mainboard’s support for locked or some unlocked CPUs. Short pin 1~2 if you intend to install a locked CPU onboard.

Short pin 2~3 if you intend to install an unlocked CPU for overclocking purposes.

Slots

The motherboard provides one AGP slot, three 32-bit Master PCI bus slots, and one CNR slot.

AGP Slot

PCI Slots

CNR Slot

AGP (Accelerated Graphics Port) Slot

The AGP slot allows you to insert the AGP graphics card. AGP is an interface specification designed for the throughput demands of 3D graphics.

It introduces a 66MHz, 32-bit channel for the graphics controller to directly access main memory.

PCI (Peripheral Component Interconnect) Slots

The PCI slots allow you to insert the expansion cards to meet your needs.

When adding or removing expansion cards, make sure that you unplug the power supply first. Meanwhile, read the documentation for the expansion card to make any necessary hardware or software settings for the expansion card, such as jumpers, switches or BIOS configuration.

CNR (Communication Network Riser) Slot

The CNR slot allows you to insert the CNR expansion cards. CNR is a specially designed network, audio, or modem riser card for ATX family motherboards. Its main processing is done through software and controlled by the motherboard’s chipset.

PCI Interrupt Request Routing

The IRQ, acronym of interrupt request line and pronounced I-R-Q, are hardware lines over which devices can send interrupt signals to the microprocessor. The PCI IRQ pins are typically connected to the PCI bus INT

A# ~ INT D# pins as follows:
