DDR DIMM sockets. These two 184-pin DIMM sockets support up to 2GB using unbuffered non-ECC PC2700/2100/1600 DDR DIMMs.

North bridge controller. This SiS651 controller integrates a high performance host interface for the Intel® Pentium® 4/Celeron processor, a DDR 333/266 memory controller, and the SiS MuTIOL® technology that allows interface with the south bridge controller at rates of up to 1GB/s.

5IEEE 1394 controller. This 1394 controller provides up to 400 Mbps data trasfer rate for throughput devices such as DV camcorders, digital cameras, scanners, and printers.

6AudioDJ controller. This chip allows you to play MP3 files from the optical drive or from your hard disk drive without entering the operating system.

7Audio CODEC. This chip is an AC ’97 compliant audio CODEC that allows 6-channel audio playback.

8Card reader controller. This is a 6-in-1 card reader controller with USB 1.1 interface that allows faster data transfer rates for storage cards.

9Card reader firmware. This chip contains the programmable EEPROM for the card reader.

10Flash EEPROM. This 4Mb ISA chip contains the programmable BIOS program.

11Super I/O chipset. This Low Pin Count (LPC) interface provides the commonly used Super I/O functionality. The chipset supports a Standard Infrared (SIR), TV remote control, PS/2 mouse, PS/2 keyboard, card reader, and Flash ROM. It also employs the SmartGuardian technology that monitors CPU and chassis fan speeds and other system conditions.
