System Board Components

Function
Pentium III 500-MHz processor with 100 MHz FSB
Uses Accelerated Hub Architecture to make direct 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.
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.
