1 ATX power connector. This 20-pin connector connects to an ATX power supply. The power supply must have at least 2A on the +5VSB lead and 15A on the +12V lead. 2 ATX 12V connector. This power connector connects the 4-pin 12V plug from the ATX 12V power supply. 3 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. 4 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 SouthBridge ICH5 via the Intel® proprietary Hub Interface. 5 Super I/O controller. This Winbond Low Pin Count (LPC) interface provides the commonly used Super I/O functionality. The chipset supports a highperformance 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. 6 DDR DIMM sockets. These two 184-pin DIMM sockets support up to 2GB system memory using unbuffered non-ECC PC3200/2700/2100 DDR DIMMs. 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 SATA connectors. These connectors support Serial ATA HDDs and allow up to 150MB/s data transfer rate using thin 4-conductor SATA cables. 10 Flash ROM. This 4Mb firmware contains the programmable BIOS program. 11 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 controller, LPC interface, AC'97 2.3 interface, and PCI 2.3 interface. The ICH5 also contains the necessary arbitration and buffering for efficient utilization of these interfaces. 12 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. 13 Wi-Fi slot. This slot supports the ASUS WiFi-b™ and the upcoming 802.11g wireless add-on cards. The ASUS WiFi-b™ is compliant to the 802.11b standard and also provides the Software AP (Access Point) userfriendly utility. With ASUS WiFi-b™, establishing a home network is hasslefree. 1-6 Chapter 1: Product introduction
