System Board Components

Component	Function
Pentium III Processor	667-MHz or higher processor , 133-MHz or higher FSB
Intel 820 Chipset:
82820 Memory Controller Hub	Uses Intel graphics technology, software drivers, and
(MCH)	Direct AGP (integrated AGP) to create vivid 2D and 3D
	effects and images. Features integrated Hardware Motion
	Compensation to improve video quality.
	Features processor and host bus optimized for the
	processor, integrated RDRAM controller, 3D graphics
	visual enhancements, 3D graphics texturing
	enhancements, digital video output, integrated 24-bit
	230 MHz RAMDAC, 2D graphics, arithmetic stretch blitter
	video, integrated graphics memory controller, display
	cache interface, arbitration scheme and concurrency, data
	buffering, power management functions, and support for
	I/O bridge.
82801AA I/O Controller Hub	Uses Accelerated Hub Architecture to make direct
(ICH)	connection from graphics and memory to the integrated
	AC97 controller, IDE controller, and dual USB ports.
	Supports PCI bus interface, integrated IDE controller,
	USB, AC’97 Link for audio and telephone Codecs,
	interrupt controller, timers, 3.3V operation, power
	management logic, enhanced DMA controller, real-time
	clock, SM bus, and Firmware Hub.
82802 Firmware Hub (FWH)	Stores system BIOS and video BIOS, eliminating a
	redundant nonvolatile memory component. In addition, the
	82802 contains a hardware Random Number Generator
	(RNG). The Intel RNG provides truly random numbers to
	enable fundamental security building blocks supporting
	stronger encryption, digital signing, and security protocols.
	Features Intel Platform Compatibility, Firmware Hub
	Hardware Interface Mode, configurable interfaces, flash
	memory for non-volatile storage, and address/address
	multiplexed interface mode.
