ATX 12V connector. This power connector connects the 4-pin 12V plug from
1
the ATX 12V power supply.
CPU socket. A 478-pin surface mount, Zero Insertion Force (ZIF) socket for
2
®
the Intel
6.4GB/s, 4.3GB/s, and 3.2GB/s data transfer rates, respectively.
North bridge controller. The Intel
3
Controller Hub 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 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 PC3200/2700/2100 DDR DIMMs.
ATX power connector. This 20-pin connector connects to an ATX +12V
5
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.
Floppy disk connector. This connector accommodates the provided ribbon
7
cable for the floppy disk drive. One side of the connector is slotted to prevent
incorrect insertion of the floppy disk cable.
IDE connectors. These dual-channel bus master IDE connectors support
8
Ultra ATA100/66/33, PIO Modes 0-4 IDE devices. Both the primary (blue) and
secondary (black) connectors are slotted to prevent incorrect insertion of the
IDE ribbon cable.
AGP slot. This Accelerated Graphics Port (AGP) slot supports AGP 8X/4X
9
mode graphics cards for 3D graphical applications.
SATA connectors. These connectors support Serial ATA HDDs and allows
10
for up to 150MB/s data transfer rate, faster than the standard Parallel ATA
with 133 MB/s.
Flash EEPROM. This 4Mb firmware hub contains the programmable BIOS
11
program.
Serial (COM2) connector. This connector accommodates a second serial
12
port using an optional serial port bracket.
South bridge controller. The fourth-generation Intel I/O Controller Hub
13
(ICH5) is a subsystem that integrates various I/O functions including 2-channel
ATA100/66/33 bus master IDE controller, up to eight USB 2.0/1.1 ports, I/O
APIC, SMBus 2.0 controller, and PCI 2.3 interface. The ICH5 also contains
the necessary arbitration and buffering for efficient utilization of these
interfaces.
