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
Intel
®
Pentium
TM
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.
