MSI MS-6301 User manual

CHAPTER 1 INTRODUCTION
1-1
The MS-6301 ATX CA8 mainboard is a high-performance computer
mainboard based on Intel®820 chipset. The MS-6301 is designed for the
Intel®PentiumTM II/III processor for high-end business/personal desktop
markets.
The Intel®820 chipset is the first generation chipset for the Intel®Pentium®
II/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), Memory Translator Hub (MTH), the I/O Controller Hub
(ICH) and the Firmware Hub (FWH). The MCH integrates a 100MHz/
133MHzCPUFSB,andafix100MHzSDRAMcontrollerandhigh-speedhub
interface for communication with the ICH. The ICH integrates an Ultra ATA/
66(ICH)controller, USBhostcontroller, 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.

2.1-2 CPU Core Speed Derivation Procedure
The mainboard CPU Core/Bus ratio and CPU Bus Frequency can
both be set through BIOS setup
If CPUClock = 100MHz
Core/Bus ratio = 4
then CPU core speed = Host Clock x Core/Busratio
= 100MHz x 4
= 400MHz
