MSI MS-6199VA User manual

CHAPTER 1 INTRODUCTION

1-1

The MS-6199VA ATX VIA mainboard is a high-performance personal

computer mainboard based on the Intel®Pentium®II/III processor. The Intel®

Pentium®II/III processor supports MMXTM (Multimedia Extension) technol-

ogy.

The mainboard uses the highly integrated VIA®VT82C693A chipset to

support the PCI/ISA and Green standards, and to provide the Host/AGP

bridge. TheVIA®VT82C596B chipset integrates all system control functions

such as ACPI (Advanced Configuration and Power Interface). The ACPI

provides more Energy Saving Features for the OSPM(OS Direct Power

Management) function. The VIA®VT82C596B chipset also improves the

IDE transfer rate by supporting Ultra DMA 33/66 IDE that transfers data at

the rate of 33/66MB/s.

The mainboard also supports the System Hardware Monitor Controller. Its

functions include: CPU /power supply/chassis fan revolution detect, CPU/

system voltage monitor, system temperature monitor, chassis intrusion

detect and TOP TECH III as an optional function.

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

processor lock shown above.

Note: The Retention Mechanism processor lock can only lock S.E.C.C. 2

and S.E.P.P. processor.

2.1-2 CPU Core Speed Derivation Procedure

1. This mainboard can auto-detect the Core/Bus (Fraction) ratio of the CPU

If CPUClock = 66MHz

Core/Bus ratio = 3.5

then CPU core speed = Host Clock x Core/Bus ratio

= 66MHzx3.5

= 233MHz

Note: CPU Vcore and Vi/o can be modified through CMOS.

Vcoreis for CPU.

Vi/oisforNorthbridge (VT82C693A).

2.1-3 Overclocking Jumper: SW2/SW3

Overclocking is a process of operating a CPU/Processor beyond its

specified frequency. SW2/SW3 is used for overclocking.

SW2 SW3 Feature

Automatically detect 66MHz, 100MHz,

133MHz CPU Bus Frequency

Virtually set CPU Bus Frequency

into 100MHz

Virtually set CPU Bus Frequency

into 133MHz

Note If you used this jumper for overclocking, you also need to modify the

CPU Bus ratio thorugh CMOS.

2.1-4 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.

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.
