1-8 Chapter 1: Product introduction
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 ® 848P Memory 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 Intel
® 848P Memory Controller Hub interconnects
to the ICH5R South bridge via the Intel ® proprietary Hub Interface.
DDR DIMM sockets. These three 184-pin DIMM sockets support
up to 2GB system memory using unbuffered non-ECC PC3200/
2700/2100 DDR DIMMs.
ATX power connector. This 20-pin connector connects to an ATX
power supply. The power supply must have at least 1A on the +5V
power for standby lead (+5VSB).
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.
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.
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.
AGP 8X slot. This Accelerated Graphics Port (AGP) slot supports
1.5V AGP 8X/4X mode graphics cards for 3D graphical applications.
SATA connectors. These connectors support Serial ATA HDDs
and allow up to 150MB/s data transfer rate using thin 4-conductor
SATA cables.
Flash ROM. This 4Mb firmware contains the programmable BIOS
program.
