CHAPTER 2 HARDWARE INSTALLATION Chapter 2 HARDWARE INSTALLATION 2.1 Central Processing Unit: CPU The mainboard operates with Intel® Pentium® II processor with MMXTM technology. The mainboard uses a CPU Slot called Slot 1 for easy CPU installation and a DIP switch (SW1) to set the proper speed for the CPU. The CPU should always have a Heat Sink and a cooling fan attached to prevent overheating.
CHAPTER 2 HARDWARE INSTALLATION 2.1-1 CPU Installation Procedures There are two kinds of Pentium® II processor that is currently used: the OEM Pentium® II processor and the Boxed Pentium® II processor. OEM Pentium® II processor has no Heat Sink, Fan and Heat Sink Support, while the Boxed Pentium® II processor is provided with Heat Sink w/ fan and Heat Sink Support. A.
CHAPTER 2 HARDWARE INSTALLATION *Heat Sink Support Pin (HSSPIN) - Plastic pins inserted through the HSSBASE to secure it to the mainboard (2 required per Assembly). *Heat Sink Support Top Bar (HSSTOP) - Plastic bar that clips onto the HSSBASE through the fins on the ATX heatsink. **Heat Sink w/ fan - Heat Sink that can be attached to the Pentium® II processor with metal clip. Note: * Provided by MSI mainboard. ** Provided by Special request.
CHAPTER 2 HARDWARE INSTALLATION Step 1: Insert the Retention Mechanism Attach Mount at the bottom of the mainboard. Step 2: Install the Retention Mechanism. Look for the key on Slot 1, and match it with the Notch Key on the Retention Mechanism for proper direction. Then, attach the Retention Mechanism to the Retention Mechanism Attach Mount. Use a Screwdriver to secure the Retention Mechanism.
CHAPTER 2 HARDWARE INSTALLATION Step 3: Install the Heat Sink Support Base. Look for the Two holes across Slot 1, and match it with the Two legs of the Heat Sink Support Base for the proper direction. Take note that one hole/leg is bigger than the other. The Four top pins of the Heat Sink Support Base should also be oriented towards Slot 1. pins Heat Sink Support Pin Leg Heat Sink Support Base Push the Heat Sink Support Base onto the mainboard, until you hear a click sound. Check for a perfect fit.
CHAPTER 2 HARDWARE INSTALLATION Step 5: Install the Heat Sink with Fan to the Processor. Push down the metal clips, so that they are in line with the back of the Heat Sink. Be careful, so as not detach the metal clips from the Heat Sink. Heat Sink w/ Fan â should be The arrow pointing down. Heat Sink Base Holder Metal Clips In case the metal clips are detached from the Heat Sink, re-attach them. Look for the arrow on the metal clip.

CHAPTER 2 HARDWARE INSTALLATION B. Boxed Pentium® II processor Installation Procedures The Boxed Pentium® II processor has a built- in Fan and Heat Sink. It also has a Heat Sink Support. So if you’re going to use the Boxed processor, all you need is the Retention Mechanism. Step 1: Insert the Retention Mechanism Attach Mount at the bottom of the mainboard. Step 2: Install the Retention Mechanism. Look for the key on Slot 1, and match it with the Notch Key on the Retention Mechanism for proper direction.
CHAPTER 2 HARDWARE INSTALLATION Step 3: Install the Heat Sink Support Base. Look for the 2 holes across Slot 1, and match it with the 2 Heat Sink Support Base. Take note that one hole/base is bigger than the other. Retention Mechanism Notch Hole PC-3742 Heat Sink Support Base Push the Heat Sink Support Base onto the mainboard, until you hear a click sound. Check for a perfect fit.
CHAPTER 2 HARDWARE INSTALLATION Step 4: Install the Heat Sink Support. Attach the 2 Heat Sink Supports to the sides of the Processor. These Heat Sink Supports will fit in any direction, so be sure that the Heat Sink Support Locks are oriented outwards for the proper direction.

CHAPTER 2 HARDWARE INSTALLATION 2.1-2 CPU Speed Setting: SW1 To adjust the speed of the CPU, you must know the specifications of your CPU (always ask the vendor for CPU spec.). Then look at Table 2.1 (200 ~ 333MHz/300 ~ 500MHz Intel® Pentium® II processor) for setting. SW1 ON DIP ON OFF 1 2 3 4 5 6 Speed Setting Table 2.1 200 ~ 333MHz/300 ~ 500MHz Intel® Pentium® II processor CPU SPEED (FSB 66/100MHz) CORE/BUS RATIO SW1 DIP ON ON 200/300MHz OFF 1 2 ON 233/350MHz 3 (i.e.
CHAPTER 2 HARDWARE INSTALLATION Note: If user set pin 5 of SW1to “ON”, then the motherboard can set the 66.6MHz CPU to 100MHz FSB. Divide the CPU speed by the FSB frequency and get the closest core/ bus ratio then set pins 1 to 4 of SW1. Though the motherboard provides this function, it is not recommended because it might cause instability, or unable to power on. Long term usage may shorten the lifespan of the CPU. Thus, we strongly discourage the use of this function except for testing purposes.
