Processor and Secondary Cache
The system uses an Intel Pentium III processor with an internal clock speed of 600 MHz or
higher (depending on type of processor).
The processor is an advanced pipelined 32-bit addressing, 64-bit data processor designed to
optimize multitasking operating systems. The 64-bit registers and data paths support 64-bit
addresses and data types.
To use the processor's power, the system features an optimized 64-bit memory interface and
256 KB of secondary write-back cache on the processor.
The processor is compatible with 8-, 16-, 32-, and 64-bit software written for the Intel386
™
Intel486
, Pentium, Pentium II, and Pentium III processors. The processor is installed in a
Socket 370 on the system board.

Function
Uses Accelerated Hub Architecture to make direct
connection from graphics and memory to the integrated
AC97 controller, IDE controller, and 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.
The controller supports the following:
Multimode parallel port
Centronics compatible (standard mode)
Enhanced capabilities port (ECP)
Enhanced parallel port (EPP)
Two RS-232C serial ports
Integrated 8042A keyboard controller
Mouse controller
Hardware monitor
Industry-standard floppy controller
Audio/modem integrated on system board, compatible with
Windows Sound System
