1-5

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

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

6.4GB/s, 4.3GB/s, and 3.2GB/s data transfer rates, respectively.

North bridge controller. The Intel

865G Graphics Memory Controller Hub

(GMCH) provides the processor interface with 800/533/400 MHz frequency,
system memory interface at 400/333/266MHz operation, and 1.5V AGP
interface that supports AGP 3.0 specification including 8X Fast Write protocol.
The GMCH 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
system memory using unbuffered non-ECC PC3200/2700/2100 DDR DIMMs.

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.

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

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).

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.

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

SATA connectors. These connectors support Serial ATA HDDs and allow
up to 150MB/s data transfer rate using thin 4-conductor SATA cables.

South bridge controller. The fifth-generation Intel I/O Controller Hub (ICH5)
is a subsystem that integrates various I/O functions including 2-channel
ATA100 bus master IDE controller, SATA 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.

PCI slots. These 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 Realtek ALC650 is an AC’97 CODEC that allows
6-channel audio playback.

LAN controller. This Realtek RTL8101L LAN controller supports
10BASE-T/100BASE-TX networking.
