This chapter describes the motherboard features and the new technologies it supports 1.1 Welcome! The motherboard delivers a host of new features and latest technologies, making it another line of BCM long life motherboards! Before you start installing the motherboard, and hardware devices on it, check the items in your package with the list below.
1.3 Special Features 1.3.1 Product Highlights Intel® Core 2 Processor Ready This mainboard supports the latest Intel® Core 2 processor in the LGA775 package. With the new Intel® Core 2 micorarchitecture technology and 1333/1066/800 MHz FSB, Intel® Core 2 processor is one of the most powerful and energy efficient CPU in the world.
Page 13
USB 2.0 Technology The mainboard implements the Universal Serial Bus (USB) 2.0 specification, dramatically increasing the connection speed from the 12Mbps bandwidth on USB1.1 to a fast 480Mbps on USB2.0. USB2.0 is backward compatible with USB1.1.
1.4 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings. • Unplug the power cord from the wall socket before touching any component. • Use a grounded wrist strap or touch a safely grounded object or to a metal object, such as the power supply case, before handling components to avoid damaging them due to static electricity •...
1.5 Mainboard Overview Before you install the mainboard, study the configuration of your chassis to ensure that the motherboard fits into it. Make sure to unplug the power cord before installing or removing the mainboard. Failure to do so can cause you physical injury and damage mainboard components. 1.5.1 Placement direction When installing the mainboard, make sure that you place it into the chassis in the correct orientation.
PnP cap/socket pins/motherboard components. BCM will shoulder the cost of repair only, if the damage is shipment/ transit-related. • Keep the PnP cap after installing the mainboard. BCM will process Return Merchandise Authorization (RMA) requests only if the mainboard comes with the cap on the LGA775 socket.
1.6.1 Installing the CPU To install a CPU 1. Locate the CPU socket on the motherboard 2. Press the load lever with your thumb (A) and move it to the left (B) until it is released from the retention tab. To prevent damage to the socket pins, do not remove the PnP cap unless you have installed the CPU.
Page 19
4. Lift the load plate with your thumb and forefinger to a 100° angle (A), then push the PnP cap from the load plate window to remove (B). 5. Position the CPU over the socket, making sure the gold triangle is on the bottom-left corner of the socket.
1.6.2 Installing the CPU heatsink and fan The Intel Pentium 4 LGA775 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. • When you buy a boxed Intel® Core 2 processor, the package includes the CPU fan and heatsink assembly.
Page 21
Push down two fasteners at a time in a diagonal sequence to secure the heatsink and fan assembly in place 3. Connect the CPU fan cable to the connector on the motherboard labeled CPUFAN1. Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug in this connector.
1.6.3 Uninstalling the CPU heatsink and fan. To uninstall the CPU heatsink and fan: 1. Disconnect the CPU fan cable from the connector on the motherboard. 2. Rotate each fastener counterclockwise. 3. Pull up two fasteners at a time in a diagonal sequence to disengage the heatsink and fan assembly from the mainboard.
Page 23
4. Rotate each fastener clockwise to ensure correct orientation when reinstalling. The narrow end of the groove should point outward after resetting. (The photo shows the groove shaded for emphasis.)
1.7 System Memory 1.7.1 Overview The mainboard comes with four 240-pin DDR2 Dual Inline Memory Modules (DIMM) sockets. You may use 667MHz (PC2-5300), or 800MHz (PC2-6400); Non-ECC, Un-buffered 1.8V DDR2 memory modules on this board (2GB maximum for each slot). It is recommended to use 667MHz DIMM for 8GB configuration. 1.7.2 Dual-Channel mode Population Rule In Dual-Channel mode, the memory modules can transmit and receive data with two data bus lines simultaneously.
1.7.3 Installing DIMM Make sure to unplug the power supply before adding or removing DIMMS or other system components. Failure to do so may cause severe damage to both the mainboard and the components. 1. Unlock a DIMM socket by pressing the retaining clips outward. 2.
3. DDR2 memory modules are not interchangeable with DDR and is DDR2 standard is not backward compatible. You shall always install DDR2 memory modules in the DDR2 memory slots. 4. To enable the system boot-up successfully, always inset the memory module into the DMM_A1 slot first.
1.8 Power Supply 1.8.1 ATX 24-pin Power Connector: JPWR3 This connector connects to an ATX 24-pin connector from power supply unit (PSU). To connect the ATX 24-pin power connector, make sure the 24-pin power connector from PSU is inserted in the proper orientation and the pins are aligned.
Page 28
1. For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12 V specification 2.0 ( or later version) and provides a minimum power of 350W. 2. Do not forget to connect the 4-pin JPW1 power plug; otherwise, the system will not boot.

“Shut down” and then click “Shut down the computer” The power supply should turn off after windows shut down.
Chapter 3: BIOS Setup 3.1 Introducing BIOS The BIOS is a program located on a Flash Memory on the motherboard. This program is a bridge between motherboard and operating system. When you start the computer, the BIOS program gains control. The BIOS first operates an auto-diagnostic test called POST (power on self test) for all the necessary hardware, it detects the entire hardware device and configures the parameters of the hardware synchronization.
3.3 Getting Help Main Menu The main menu lists the setup functions you can make changes to. You can use the arrow keys to select the item. The on-line description of the highlighted setup function is displayed at the bottom of the screen.

hardware components turn off to save energy. The information stored in memory will be used to restore the system when a “wake up” event occurs. • Suspend Time Out (Minute) If system activity is not detected for the length of time specified in this field, all devices except CPU will be shut off.
Page 57
• Resume From S3 By PS/2 Mouse This setting determines whether the system will be awakened from what power saving modes when input signal of the PS/2 mouse is detected. • Resume By PCI Device (PME#) When set to [Enabled], the feature allows your system to be awakened from the power saving modes through any event on PME (Power Management Event).
3.9 PnP/PCI Configurations This section describes configuring the PCI bus system and PnP (Plug & Play) feature. PCI, or Peripheral Component Interconnect, is a system which allows I/O devices to operate at speeds nearing the speed the CPU itself uses when communicating with its special components. This section covers some very technical items and it is strongly recommended that only experienced users should make any changes to the default settings.
