Chapter 2 Hardware Installation This chapter gives you a step-by-step procedure on how to install your system. Follow each section accordingly. 2.1 ESD Precautions Electrostatic discharge (ESD) can damage your processor, disk drives, expansion boards, and other components. Always observe the following precautions before you install a system component. 1. Do not remove a component from its protective packaging until you are ready to install it. 2.

Hardware Installation 2.3 Setting the Jumper Set a jumper switch as follows: • • To open a jumper, remove the jumper cap. To close a jumper, insert the plastic jumper cap over two pins of a jumper. The conventions in the figure are used to represent the proper jumper settings.
Hardware Installation 2.4 Installing a Microprocessor The motherboard comes with a zero-insertion force (ZIF) microprocessor socket that allows you to install a CPU without using any tool. Follow these steps to install a CPU into a ZIF-type CPU socket: Make sure that the system power is OFF before installing a component. 1. Locate the CPU socket on the system board and pull up the socket lever. Hole 1 2. Gently insert the CPU. Make sure that pin 1 of the CPU aligns with hole 1 of the socket.
Hardware Installation 4. Attach the heatsink and fan to the CPU. 5. Plug the fan cable onto the two-pin fan connector onboard. The fan connector is marked CN15 on the system board.
Hardware Installation 6. Set jumpers JP1 and JP10 according to the frequency of the CPU that you install. CPU FREQUENCY SELECT JP1 JP10 75 MHz 90 MHz 100 MHz (default) 120 MHz 133 MHz 150 MHz 166 MHz 7. Set jumper JP11 according to the CPU voltage. CPU VOLTAGE SELECT JP11 3.45V (default) 3.
Hardware Installation 2.5 Upgrading the Microprocessor To upgrade a CPU: 1. Turn off the system power and remove the housing cover. 2. Locate the CPU socket on the system board. 3. Pull up the socket lever. 4. Remove the installed CPU, if any. 5. Install the upgrade CPU. Refer to section 2.3 for instructions on how to install a CPU. 2.6 Configuring the System Memory The system board has four 72-pin SIMM sockets that allow you to expand the system memory to 512 MB.

Hardware Installation 2.6.1 Installing a SIMM Observe the ESD precautions when installing components. Follow these steps to install a SIMM: 1. Slip a SIMM at a 45° angle into a socket. If the SIMM does not completely fit into the socket, reverse the SIMM orientation. The SIMM has a curved edge indicating pin 1 that ensures installation in one direction only. curved edge Be careful when inserting or removing SIMMs. Forcing a SIMM in or out of a socket can damage the socket or the SIMM (or both). 2.
Hardware Installation 2.6.2 Removing a SIMM To remove a SIMM: 1. Press the holding clips on both sides of the SIMM outward to release it. 2. Press the SIMM downward to about a 45° angle. 3. Gently pull the SIMM out of the socket.
Hardware Installation 2.7 Customizing your Hardware Setup You may customize your hardware setup according to your desired system performance. However, doing so requires resetting of several jumpers. The onboard jumpers are normally set to its default setting. See the figure in section 2.2 for the location of the jumpers on the system board. The following sections tell how to configure the system board to meet the desired performance: 2.7.
Hardware Installation 2.7.3 Selecting the ECP DMA Channel The available ECP DMA channel selections are DRQ3/DACK3 and DRQ1/DACK1. The default is DRQ3/DACK3. To select DRQ1/DACK1, reset jumpers JP6 and JP7 to 2-3. JP6 JP7 DRQ3/DACK3 (default) DRQ1/DACK1 The onboard I/O controller may either be SMC 665 or SMC 669. If you have SMC 669, JP6 and JP7 must be set to open. 2.7.4 Clearing the CMOS You need to clear the CMOS if you forget your system password.
Hardware Installation 2.7.5 Disabling the PS/2 Mouse Function The PS/2 mouse function is normally enabled and occupies IRQ12. To reassign IRQ12 to another function, you need to disable the PS/2 mouse function by opening jumper JP4 and changing the BIOS setup. For detailed information on BIOS, see Chapter 3. JP4 Enabled (default) Disabled 2.7.6 Setting the Keyboard Clock The jumper JP1401 enables you to set the keyboard clock. The clock selections are ISA clock and 12 MHz.
Hardware Installation 2.8 Installing the System Board Make sure that you have already installed the system board components like the CPU and memory, and have set the appropriate jumpers before you proceed. Follow these steps to install a system board into a housing: 1. Open the system housing. Refer to the housing documentation for steps on how to remove the housing cover. 2. Install the board into the housing and secure it with the screws that come with the housing. 3.
Hardware Installation 2.9 Connecting Peripherals 2.9.1 Power Cable A standard power supply has two cables with six wires each. Plug these cables to the onboard power connector in such a way that all the black wires are in the center. The power connector is marked CN3 on the system board. Make sure that the power supply is off before connecting or disconnecting the power cable. 2.9.2 Mouse PS/2 Mouse To connect a PS/2 mouse, simply insert the PS/2 bracket connector onto CN4 on the system board.
Hardware Installation Serial Mouse To connect a serial mouse, plug in the serial bracket connectors onto the CN6 and CN7. Insert the serial mouse connector into the appropriate COM port on the bracket. See section 2.9.3. 2.9.3 Serial Devices (COM1/COM2) To support serial devices, insert the serial device connector into the serial port on the bracket. Plug in the serial port bracket connectors onto the appropriate onboard connectors.
Hardware Installation 2.9.5 Printer Plug in the printer bracket connector onto the onboard parallel connector marked CN9 on the board. Refer to the figure. The printer port on the bracket accepts the printer cable. 2.9.6 IDE Devices Primary IDE Connector The primary IDE connector marked CN10 on the system board supports two IDE devices - one IDE hard disk and one additional IDE device. Connect your IDE HDD into the master port of the primary IDE cable.
Hardware Installation Secondary IDE Connector The secondary IDE connector is marked CN11 on the board. This connector also supports two IDE devices. To install an IDE CD-ROM drive into your system, insert master port of the secondary IDE cable into the CD-ROM drive connector. If you have more than two hard disks, connect your third hard disk into the master port. Connect your CD-ROM drive into the slave port. 2.9.7 Front-panel Switches and LEDs HDD LED The HDD LED connector is marked CN12 on the board.
Hardware Installation Some housings have a five-pin connector for the keylock and power LED. Speaker Reset Other housings may have a 12-pin connector. If your housing has this type of connector, plug it onto CN16 as shown in the following figure. Make sure that the red wire of the connector connects to pin 11. Keylock & Power LED Break Switch ( Turbo Switch ) Green Mode LED ( Turbo LED ) Ground Reset Res-VCC Speaker Keylock Ground Break Switch ( Turbo Switch ) VCC Ground 2.9.
Hardware Installation 2.10 Installing Expansion Boards Before you install any expansion board, make sure that you have secured the system board in the housing. Follow these steps to install an expansion board: 1. Observe the ESD precautions before removing the expansion board from its protective packaging. 2. Locate an empty expansion slot on the system board. 3. Remove the bracket opposite the slot that you want to use. Save the cover and screw for future use. 4.
