ATX 12V connector. This power connector connects the 4-pin 12V plug from

1

the ATX 12V power supply.

2

CPU socket. A 478-pin surface mount, Zero Insertion Force (ZIF) socket for

®

®

the Intel

Pentium

4 Processor, with 800/533/400 MHz system bus that allows

4.3GB/s, and 3.2GB/s data transfer rates, respectively.

®

3

North bridge controller. The Intel

82865P Memory Controller Hub (MCH)

provides the processor interface with 533/400 MHz frequency, system

memory interface at 333/266MHz operation and an AGP interface that

supports AGP 3.0 specification including 8X Fast Write protocol. The MCH

®

interconnects to the south bridge ICH5 via the Intel

proprietary Hub Interface.

DDR DIMM sockets. These four 184-pin DIMM sockets support up to 4GB

4

system memory using unbuffered non-ECC PC2700/2100 DDR DIMMs.

5

ATX power connector. This 20-pin connector connects to an ATX power

supply. The power supply must have at least 1A on the +5V standby lead

(+5VSB).

Super I/O controller. This Winbond Low Pin Count (LPC) interface provides

6

the commonly used Super I/O functionality. The chipset supports a high-

performance floppy disk controller for a 360K/720K/1.44M/2.88M floppy disk

drive, a multi-mode parallel port, two standard compatible UARTs, and a Flash

ROM interface. This controller also integrates the ASIC for PC health

monitoring.

7

Floppy disk connector. This connector accommodates the provided ribbon

cable for the floppy disk drive. One side of the connector is slotted to prevent

incorrect insertion of the floppy disk cable.

8

IDE connectors. These dual-channel bus master IDE connectors support

Ultra DMA100/66, PIO Modes 3 & 4 IDE devices. Both the primary (blue) and

secondary (black) connectors are slotted to prevent incorrect insertion of the

IDE ribbon cable.

9

AGP 8X slot. This Accelerated Graphics Port (AGP) slot supports 0.8V/1.5V

AGP 8X mode graphics cards for 3D graphical applications.

10

SATA connectors. These connectors support Serial ATA HDDs and allows

for up to 150MB/s data transfer rate, faster than the standard Parallel ATA

with 133 MB/s.

11

Flash ROM. This 4Mb firmware contains the programmable BIOS program.

South bridge controller. The fifth-generation Intel I/O Controller Hub (ICH5)

12

is a subsystem that integrates various I/O functions including 2-channel

ATA100 bus master IDE controller, up to eight USB 2.0/1.1 ports, I/O APIC,

SMBus 2.0 controller, LPC interface, AC’97 2.2 interface, and PCI 2.2

interface. The ICH5 also contains the necessary arbitration and buffering for

efficient utilization of these interfaces.

13

Standby power LED. This LED lights up if there is a standby power on the

motherboard. This LED acts as a reminder to turn off the system power before

plugging or unplugging devices.

WiFi slot. The WiFi (Wireless Fidelity) slot connects a Wi-Fi certified

14

equipment for wireless networking that allows 11Mbps transmission (with a

fallback to 5.5, 2 and 1 Mbps) in the 2.4 GHz band. Wi-Fi networks use

radio technologies known as IEEE 802.11b to provide a fast reliable

wireless connectivity.

15

PCI slots. These five 32-bit PCI 2.2 expansion slots support bus master

PCI cards like SCSI or LAN cards with 133MB/s maximum throughput.

Audio CODEC. The ADI AD1985 is an AC’97 CODEC that allows 6-channel

16

audio playback. The audio CODEC provides six DAC channels for 5.1

surround sound, S/PDIF output, AUX and Line In stereo inputs, integrated

headphone amplifier, and supports greater than 90dB dynamic range.

®

LAN controller. This 3Com

3C940 Gbit PCI LAN controller support

17

10BASE/100BASE/1000BASE-TX networking.

18

PS/2 mouse port. This green 6-pin connector is for a PS/2 mouse.

Parallel port. This 25-pin port connects a parallel printer, a scanner, or other

19

devices.

RJ-45 port. This port allows connection to a Local Area Network (LAN)

20

through a network hub.

Line In jack. This Line In (light blue) jack connects a tape player or other

21

audio sources. In 6-channel mode, the function of this jack becomes Rear

Speaker out.

22

Line Out jack. This Line Out (lime) jack connects a headphone or a

speaker. In 6-channel mode, the function of this jack becomes Front

Speaker Out.

23

Microphone jack. This Mic (pink) jack connects a microphone. In 6-channel

mode, the function of this jack becomes Bass/Center Speaker Out.

The functions of the Line Out, Line In, and Microphone jacks change when you

select the 6-channel audio configuration as shown in the following table:
