MSI MS-6187 User manual

CHAPTER 1 INTRODUCTION
1-1
The MS-6187 ATX CA1 mainboard is a high-performance computer
mainboard based on Intel®820 chipset. The MS-6187 is designed for the
Intel®PentiumTM II/III processor 100/133MHz FSB for high-end business/
personal desktop system.
The Intel®820 chipset provides the host interface, RAMBUS DRAM
interface, I/O interface, and AGP interface. It supports a single channel of
Direct Rambus memory technology. Its AGP interface is fully compliant with
AGP2.0specification.
The Intel®820 chipset contains three core components: the Memory
ControllerHub (MCH), the I/O Controller Hub (ICH) and theFirmware Hub
(FWH). TheMCHintegratesa 100MHz/133MHzCPUFSB, 300/356/400MHz
RDRAM controller and high-speed hub interface for communication with the
ICH. The ICH integrates an Ultra DMA 66 controller, USB host controller,
LPCinterfacecontroller,FWHinterface conroller, PCIinterfacecontroller,
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

Register (Default)
Warning: If the CPU Core/Bus ratio was set too high which causes
the system to hang, short pin JP3 and then restart the
system until boot up. The CPU core/bus ratio will then be
set to the default setting of 2. Properly shutdown the
system, and remove the short on JP3.

2.1-5 Fan Power Connectors: CPUFAN/PSFAN/SYSFAN
These connectors support system cooling fan with + 12V. It supports three
pin head connector. When connecting the wire to the connector, always
take note that the red wire is the positive and should be connected to the
+12V, the black wire is Ground and should be connected to GND. If your
mainboard has System Hardware Monitor chipset on-board, you must use a
specially designed fan with speed sensor to take advantage of this function.
For fans with fan speed sensor, every rotation of the fan will send out 2
pulses. System Hardware Monitor will count and report the fan rotation
speed.
Note: 1. Always consult vendor for proper CPU cooling fan.
2. CPU FAN supports the FAN control. You can install PC Alert
utility. This will automatically control the CPU FAN Speed according
to the actual CPU temperature.
3. During Suspend mode, FAN status can be set through BIOS.
