2. HARDWARE SETUP 2.1 Getting Started IMPORTANT: Due to Pentium 4 CPU’s power consumption requirement, an ATX12V power supply is recommended for this motherboard. For typical system configurations, an ATX12V power supply that can supply at least 230W and at least 8.5A on the +12V lead is required. For heavily-loaded configurations, an ATX12V power supply that can supply at least 300W is required.
2. HARDWARE SETUP 2.2 System Memory NOTE: No hardware or BIOS setup is required after adding or removing memory. This motherboard has four 184-pin Rambus Inline Memory Modules (RIMM) sockets. These sockets support 64Mbit, 128Mbit, and 256Mbit Direct RDRAM technologies.
2. HARDWARE SETUP 2.2.1 Installing Memory The memory module (RIMM/C-RIMM) will fit in only one orientation. IMPORTANT: Do not touch the memory module’s connectors. Handle the module only by the edges. Top: C-RIMM WMT-LX 184-Pin RIMM Sockets RIMM Sockets WMT-LX RIMM with Heat Spreader RJ-45 1. Make sure that the notch keys in the module are aligned with the small ribs inside the RIMM sockets.
2. HARDWARE SETUP 2.3 Central Processing Unit (CPU) The motherboard provides a ZIF Socket for the P4 CPU. The CPU that came with the motherboard should have a fan attached to it to prevent overheating. If this is not the case, then purchase a fan before you turn on your system.
2. HARDWARE SETUP 3.5.1 CPU Installation Step 1: Install the Baseboard A metal baseboard is required to install the heatsink to the motherboard. A rubber pad is placed between the metal board and motherboard to provide insulation to prevent shorting. Align the rubber pad over the metal baseboard so that the holes match. Align the motherboard over the rubber pad and metal baseboard so that the screws on the baseboard match up with the motherboard’s screw holes.
2. HARDWARE SETUP Step 2: Install the CPU A. L ocate the Z I F socket on the motherboard. B . Unlock the socket by pressing the lever sidesways and then lifting it up to a 9 0̊ –1 0 ˚ 0angle. C . Align the C PU over the socket such that its notched or marked corner matches the socket’s corner near the end of the lever, while making sure that the C PU is parallel to the socket. D . C arefully insert the C PU into the socket until it fits in place. The illustration below shows how to insert a C PU properly.
2. HARDWARE SETUP Step 3: Install the Heatsink Support Base Place the two heatsink support base as shown and screw in the four pan head screws. Step 4: Install the Heatsink C arefully place the fan heatsink on top of the heatsink support base and connect the fan power cable to the C PU fan connector. C onnect to the C PU fan connector.
2. HARDWARE SETUP 2.4 Expansion Cards WARNING! Unplug your power supply when adding or removing expansion cards or other system components. Failure to do so may cause severe damage to both your motherboard and expansion cards (see 3.3 Hardware Setup Procedure for more information). 2.4.1 Expansion Card Installation Procedure 1. Read the documentation for your expansion card and make any necessary hardware or software settings for your expansion card, such as jumpers. 2.
2.
2.5 External Connectors WARNING! Some pins are used for connectors or power sources. These are clearly distinguished from jumpers in the Motherboard Layout. Placing jumper caps over these connector pins will cause damage to your motherboard. IMPORTANT: Ribbon cables should always be connected with the red stripe to Pin 1 on the connectors. Pin 1 is usually on the side closest to the power connector on hard drives and CD-ROM drives, but may be on the opposite side on floppy disk drives.
3) Parallel Port Connector (Burgundy 25-pin PRINTER) You can enable the parallel port and choose the IRQ through Onboard Parallel Port (see 4.4.2 I/O Device Configuration). NOTE: Serial printers must be connected to the serial port. Parallel (Printer) Port (25-pin Female) 4) Serial Port Connectors (Teal/Turquoise 9-pin COM1) One serial port is ready for a mouse or other serial devices.
6) Universal Serial Bus Ports (Black two 4-pin USB) Two USB ports are available for connecting USB devices. For additional USB ports, you can use the USB headers (see USB Headers later in this section). NOTE: USB Function (see 4.4.3 PCI Configuration) must be Enabled to use these ports. USB 1 Universal Serial Bus (USB) 2 7) Fast-Ethernet Port Connector (RJ45) The RJ45 connector is optional at the time of purchase and is located on top of the USB connectors.
2. HARDWARE SETUP 8) Primary (Blue) / Secondary IDE Connectors (Two 40-1pin IDE) These connectors support the IDE hard disk ribbon cable. Connect the cable’s blue connector to the motherboard’s primary (recommended) or secondary IDE connector, and then connect the gray connector to your UltraDMA/100 slave device (hard disk drive) and the black connector to your UltraDMA/100 master device. It is recommended that nonUltraDMA/100 devices be connected to the secondary IDE connector.
9) Floppy Disk Drive Connector (34-1pin FLOPPY) This connector supports the provided floppy drive ribbon cable. After connecting the single end to the board, connect the two plugs on the other end to the floppy drives. (Pin 5 is removed to prevent inserting in the wrong orientation when using ribbon cables with pin 5 plugged). FLOPPY Top: RJ-45 NOTE: Orient the red markings on the floppy ribbon cable to PIN 1.
11) POWER (PWR_FAN), CPU (CPU_FAN), Fan Connectors (3 pins) These connectors support cooling fans of 350mA (4.2 Watts) or less. Orientate the fans so that the heat sink fins allow airflow to go across the onboard heat sink(s) instead of the expansion slots. Depending on the fan manufacturer, the wiring and plug may be different. The red wire should be positive, while the black should be ground. Connect the fan’s plug to the board taking into consideration the polarity of the connector.
12)Wake-On-LAN Connector (3-pin WOL) This connector connects to a LAN card with a Wake-On-LAN output, such as the HP PCI-L101 Ethernet card (see 7. Appendix). The connector powers up the system when a wakeup packet or signal is received through the LAN card. IMPORTANT: This feature requires that Wake On LAN or PCI Modem is enabled (see 4.5.1 Power Up Control) and that your system has an ATX power supply with at least 720mA +5V standby power.
14)Power Supply Connectors (20-pin block ATXPWR) (6-pin AUXPWR) (4-pin ATX12V) These connectors connect to an ATX 12V power supply. Each plug from the power supply will only insert in one orientation because of the different hole sizes. Find the proper orientation and push down firmly making sure that the pins are aligned. An auxiliary power supply may be needed depending on your system configuration.

23) Erasing the CMOS Real Time Clock (RTC) RAM A Note about Passwords BIOS Setup programs allow you to specify passwords in the Main menu. The passwords control access to the BIOS during system startup. The passwords are not case sensitive. The BIOS Setup program allows you to specify two separate passwords: a Supervisor password and a User password. When disabled, anyone may access all BIOS Setup program functions.
