INTRODUCTION
The MS-6319 ATX CA10 mainboard is a high-performance computer
®
mainboard based on Intel 820 chipset. The MS-6319 is designed for the
® TM
Intel Pentium III(FC-PGA) processor for high-end business/personal
desktop markets.
® ® ®
The Intel 820 chipset is the first generation chipset for the Intel Pentium
III processor. An integrated centralized memory arbiter allocates memory
bandwidth to multiple system agents to optimize system memory utilization.
A new chipset component interconnect, the hub interface, is designed into
the Intel 820 chipset to provide an efficient communication channel between
the memory controller hub and I/O controller hub.
The Intel 820 chipset contains four core components: the Memory Control-
ler Hub (MCH), the I/O Controller Hub (ICH), the Memory Translator Hub
(MTH), and the Firmware Hub (FWH). The MCH integrates a 100MHz/
133MHz CPU FSB, while the MTH integrates a 100MHz SDRAM controller
and high-speed hub interface for communication with the ICH. The ICH
integrates an Ultra ATA33/66(ICH) controller, USB host controller, LPC
interface controller, FWH inteface conroller, PCI interface controller, AC'97
digital controller and a hub interface for communication with the MCH.

The Intel 82802 Firmware Hub (FWH) component is part of the Intel 820
chipset. The FWH is key to enabling future security and manageability
infrastructure for the PC platform.
