MSI MS-6191 Micro ATX IR2 Manual de usuario

CHAPTER 1 INTRODUCTION

1-1

The Micro ATX IR2 mainboard is a high-performance personal computer

mainboard based on the AMD Athlon®processor. This mainboard provides

onboard Creative®ES1373 PCI technology in audio. The AMD Athlon®

processor is the newest microprocessor in the AMD K86TM family of

microprocessors.

The mainboard uses the highly integrated AMD®751 system controller and

AMD 756 peripheral controller. The AMD-751 system controller features:

the S2k system interface supports a 100Mhz clock and double-data rate

(DDR) transfers, the 33MHz 32-bit bus interface supports up to three

masters, the 66MHz AGP 1.0 compliant interface supports 2x data transfer

mode, and High Speed memory designed to support a 100MHz SDRAM (PC-

100-compatible-DIMM)withserialpresencedetect(PSD). TheAMD-756

peripheral bus controllers feature an integrated ISA bus controller, an

enhanced IDE controller with Ultra DMA-66 support, and a keyboard/mouse

controller.

The MS-6191 ATX IR2 mainboard is one of our system board to implement

the AMD-750 chipset (AMD-751 and AMD-756), which supports a single

Slot A for AMD Athlon®processor.

HARDWARE INSTALLATION

2.1 Central Processing Unit: CPU

Step 1: Install the Retention Mechanism.

Attach the Retention Mechanism to the Mainboard. Push the Plastic

lock to secure the Retention Mechanism into the mainboard.

Secure the processor by

pulling up the Retention

Mechanism Processor

Lock

Insert the processor

like inserting a PCI or

an ISA card

To release the

processor, push the

Retention Mechanism

Processor lock down

Step 2: Install the Processor.

Insert the Processor like inserting a PCI or an ISA card.

Step 3: Lock the Processor.

Lock the processor by pulling up the Retention Mechanism proces-

sor lock shown above.

2.1-2 CPU Core Speed Derivation Procedure

The Mainboard can auto-detect the processor speed. Just insert the

AMD Athlon processor into Slot A.

If CPUClock = 100MHz

Core/Bus ratio = 5

then CPU core speed = Host Clock x Core/Busratio

= 100MHz x5

= 500MHz

2.1-4 Fan Power Connectors: J9, J12, & J6

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. Ifyour

mainboardhasSystemHardwareMonitorchipseton-board,youmustusea

speciallydesignedfan with speedsensortotakeadvantage of thisfunction.

Note: 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. This is an optional function for System Hardware Monitor.

2.2 Clear CMOS Jumper: JBAT1

A battery must be used to retain the mainboard configuration in CMOS

RAM. Short 1-2 pins of JBAT1 to store the CMOS data.

Keep Data Clear Data

Note: You can clear CMOS by shorting 2-3 pin, while the system is off.

Then, return to 1-2 pin position. Avoid clearing the CMOS while

the system is on, it will damage the mainboard. Always unplug

the power cord from the wall socket.

2.3-1 Memory Bank Configuration

Themainboardsupportsamaximummemorysizeof512MBforSDRAM: It

provides two 168-pin unbufferedDIMMs (Double In-Line Memory Module)

sockets. It supports 8 MB to 256 Mbytes DIMM memory module.

A. HowtoinstallaDIMMModule

1. The DIMM slot has 2 Notch Keys “VOLT and DRAM”, so the

DIMM memory module can only fit in one direction.

2. Insert the DIMM memory module vertically into the DIMM slot.

Then push it in.

3. The plastic clip at the side of the DIMM slot will automatically

close.
