Introduction of BX6 Feature 1-3 - Layout Diagram Figure 1-1 Component Locations 1-4 Chapter 1 ® The System Block Diagram Installing the Mainboard 2-1 Chapter 2 Installing the Mainboard This BX6 mainboard not only provides all standard equipment for classic personal computers, but also provides great flexibility for meeting future upgrade demands. This chapter will introduce step by step all the standard equipment and will also present, as completely as possible, future upgrade capabilities. This mainboard is able to support all Intel Pentium II processors now on the market. (For details, see specifications in Chapter 1.) This chapter is organized according the following features: OE Installing the Mainboard to the Casing · Standard external connectors Z Jumpers and switches · Installing of the CPU. º Installing the system memory. NNNN Before proceeding with the installation Before installing the mainboard please be sure to turn off or disconnect the power supply unit. Before making any modifications to the hardware configuration of the mainboard, the power supply to any areas of the mainboard you plan to modify should be turned off to avoid unnecessary damage to the hardware. 2-2 Chapter 2 & User friendly instructions Our objective is to enable the novice computer user to perform the installation by themselves. We have attempted to write this document in a very clear, concise and descriptive manner to help overcome any obstacles you may face during installation. Please read our instructions carefully and follow them step-by-step. Installing the Mainboard 2-3 ¬ Installing the Mainboard to the Casing Most computer cases will have a base on which there will be many mounting holes that allows the mainboard to be securely attached and at the same time, prevents short circuits. There are two ways to attach the mainboard to the base. lwith spacers lor with bolts In principle, the best way to attach the motherboard is with bolts, and only if you are unable to do this should you attach the board with spacers. Take a careful look at the mainboard and you will see many mounting holes on it. Line these holes up with the mounting holes on the base. If the holes line up, and there are screw holes this means you can attach the mainboard with bolts. If the holes line up and there are only slots, this means you can only attach the mainboard with spacers. Take the tip of the spacers and insert it into the slots. After doing this to all the slots, you can slide the mainboard into position aligned with the slots. After the mainboard has been positioned, check to make sure everything is OK before putting the casing back on. Note: If the mainboard has mounting holes, but don't line up with the holes on the base and their are no slots to attach the spacers, don't worry, you can still attach the spacers to the mounting holes. Just cut the spacers (along the dotted line) (the spacer may be a little hard so be careful of our hands). In this way you can still attach the mainboard to the base without worrying about short circuits. 2-4 Chapter 2 - Standard External Connectors Inside the case of any computer several cables and plugs have to be connected. These cables and plugs are usually connected one-by-one to connectors located on the mainboard. You need to carefully pay attention to any connection orientation the cables may have and, if any, notice the position of the first pin of the connector. In the explanations that follow, we will describe the significance of the first pin. PN2(Pin 4-5-6-7) - Speaker Connector Attach the system speaker to connector PN2.

Up to four IDE interface devices are supported. Installing the Mainboard 2-9 ® Jumper and Switches You can set jumper switches on the mainboard to configure various hardware options. See Figure 1-1 for jumper locations. Throughout this section, the following symbols are used to indicate jumper settings. For 3-pin jumpers, the symbols below are used: Short Pins 1 and 2 with a jumper cap. Short Pins 2 and 3 with a jumper cap. For 2-pins jumpers, the following symbols are used: Place the jumper cap over the two pins of the jumper to Short the jumper. Remove the jumper cap to Open the jumper cap. Note: To avoid losing jumper caps, attach the removed jumper cap to one of the jumper pins. 2-10 Chapter 2 CCMOS 1 - CMOS Discharge Jumper Jumper CCMOS discharge CMOS memory. When you install the mainboard, make sure this jumper is set for Normal Operation(1-2). See the jumper below. Setting CCMOS Normal Operation (Default) Discharge CMOS Installing the Mainboard 2-11 ¯ Installation of the Pentium® II CPU 1. Mount the two black plastic pegs onto the mainboard.
