Chapter 1: Motherboard Information

CPU Sockets. Socket 462 (Socket A) Zero Insertion Force (ZIF) socket for
the AMD Duron™/Athlon™/Athlon XP™ 3000+ processors.

NorthBridge Controller. The NVIDIA

nForce2™ 400 North Bridge

controller chipset. The controller supports a 64-bit DDR memory controller
and up to 3 GB of 400/333/266/200MHz DDR memory.

DDR DIMM Sockets. Equipped with three Double Data Rate Dual Inline
Memory Module (DDR DIMM) sockets to support up to 3GB of DDR
DRAM, the newest memory standard with the highest bandwidth and
lowest latency currently available. This memory technology supplies data
transfer rates up to 3.2 GB/s for 400MHz DDR SDRAM and 2.7GB/s for
333MHz DDR SDRAM.

ATX power connector. This standard 20-pin connector connects to an
ATX 12V power supply. The power supply must have at least 1A on the
+5V standby lead (+5VSB).

Floppy Disk connector. This connector connects 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
up to four 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.

Flash ROM. This 2Mb firmware contains the programmable BIOS
program. (Refer to section “2.1 Managing and updating your BIOS” on
page 2-2 for more information)

South bridge controller. Features the brand new nVidia

nForce2

™

MCP

integrated peripheral South Bridge controller operates at 800MB/sec to
communicate with the North Bridge for maximum bandwith required for
PCI, USB and support for Fast Ethernet devices. The controller supports
standard UltraDMA133/100/66/33 and separate data paths for each IDE
channel are built-in for up to two IDE devices. The controller supports six
USB ports, one LAN port and is PCI rev2.2 compliant.

Super I/O chipset. ITE IT8708 offers support for a variety of I/O functions.
Provides two high-speed UART compatible serial ports and one parallel
port with EPP and ECP capabilities. UART2 can also be directed from
COM2 to the Infrared Module for wireless connections. The Super I/O
controller supports a floppy disk drive, PS/2 keyboard, and PS/2 mouse.

COM2 Header. This 9-pin connects to a COM2 port.

GAME port header. This header connects to a GAME port module.

ASUS ASIC. This chip performs multiple system functions that include
hardware and system voltage monitoring among others.
