2. Central Processing Unit (CPU) The motherboard comes with a surface mount 478-pin Zero Insertion Force (ZIF) socket. The socket is designed for the Intel® Pentium® 4 Northwood/Prescott processor in the 478-pin package with 512KB L2 cache. This processor supports 800/533/400MHz front side bus (FSB), and allows data transfer rates of 3.2GB/s, 2.1GB/s, and 1.6GB/s. Follow these steps to install a CPU. 1. Locate the 478-pin ZIF socket on the motherboard. 2.
3. System memory The motherboard comes with two Double Data Rate (DDR) Dual Inline Memory Module (DIMM) sockets. These sockets support up to 2GB system memory using 184-pin unbuffered non-ECC PC3200/PC2700/PC2100 DDR DIMMs. The following figure illustrates the location of the DDR DIMM sockets.

4. Expansion slots The motherboard has three PCI slots and one Accelerated Graphics Port (AGP) slot. To install and configure an expansion card: 1. Install an expansion card following the instructions that came with the chassis. NOTE: The AGP slot supports only +0.8V and +1.5V AGP cards. 2. Turn on the system and change the necessary BIOS settings, if any. See Chapter 2 for BIOS information. 3. Assign an IRQ to the card. Refer to the tables below. 4.
PCI slots There are three 32-bit PCI slots on this motherboard. The slots support PCI cards such as a LAN card, SCSI card, USB card, and other cards that comply with PCI specifications. AGP slot This motherboard has an Accelerated Graphics Port (AGP) slot that supports +0.8V AGP 8X and +1.5V AGP 4X cards. When you buy an AGP card, make sure that you ask for one with +0.8V+1.5V specification. Note the notches on the card golden fingers to ensure that they fit the AGP slot on your motherboard.
5. Jumper Clear RTC RAM (3-pin J19) This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The RAM data in CMOS, that include system setup information such as system passwords, is powered by the onboard button cell battery. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 2-3 (Normal) to pins 1-2 (Clear CMOS).
6. Connectors This section describes and illustrates the internal connectors on the motherboard. 1. Floppy disk drive connector (34-1 pin FLOPPY1) This connector supports the provided floppy drive ribbon cable. After connecting one end to the motherboard, connect the other end to the floppy drive. (Pin 5 is removed to prevent incorrect insertion when using ribbon cables with pin 5 plug).
3. IDE connectors (40-1 pin PRI_IDE, SEC_IDE) This connector supports the provided UltraDMA/100/66 IDE hard disk ribbon cable. Connect the cable’s blue connector to the primary (recommended) or secondary IDE connector, then connect the gray connector to the UltraDMA/100/66 slave device (hard disk drive) and the black connector to the UltraDMA/100/66 master device. It is recommended that you connect nonUltraDMA/100/66 devices to the secondary IDE connector.
4. Serial ATA connectors (7-pin SATA1, SATA2) These next generation connectors support the thin Serial ATA cables for Serial ATA hard disks. The current Serial ATA interface allows up to 150 MB/s data transfer rate, faster than the standard parallel ATA with 133 MB/s (Ultra ATA/133).

6. USB headers (10-1 pin USB1, USB2) If the USB ports on the rear panel are inadequate, two USB headers are available for additional USB ports. The USB headers comply with USB 2.0 specification that supports up to 480 Mbps connection speed. This speed advantage over the conventional 12 Mbps on USB 1.1 allows faster Internet connection, interactive gaming, and simultaneous running of high-speed peripherals. You may connect a USB module to any of the USB headers. 5 10 USB+5V LDM4 LDP4 GND 6 P4SD-LA USB 2.
