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 or Celeron® processors, 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 VIA® PT800 provides the processor interface with 800/533/400 MHz frequency, system memory interface at 400/ 333/266MHz operation, and 1.5V/0.8V AGP interface that supports AGP 3.0 specification including 8X Fast Write protocol.

DDR DIMM sockets. These three 184-pin DIMM sockets support up to 3GB 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 standby lead (+5VSB).

IDE connectors. These dual-channel bus master IDE connectors support Ultra DMA133/100/66, 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/0.8V 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.

South bridge controller. The VIA® VT8237 integrated peripheral controller supports various I/O functions including two Serial ATA ports, 2-channel ATA/133 bus master IDE controller, up to eight USB 2.0 ports, LPC Super I/O interface, AC’97 interface and PCI 2.2 interface.

10Floppy 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.

11Standby 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.

12Flash ROM. This 4Mb firmware contains the programmable BIOS program.

13Super I/O controller. This 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.

14Audio CODEC. The ADI 1980 is an AC’97 CODEC that allows 6-channel audio playback.
