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.

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.

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.

There are three kinds of DIMM specification supported
by this mainboard: PC133, PC100 and PC66. If you
use 66MHz CPU Bus Frequency, these three DIMM
Specs. is supported. If you use 100 MHz CPU Bus
Frequency, PC100 and PC133 DIMM Specs. is sup-
ported. If you use 133MHz CPU Bus Frequency, only
PC133 DIMM Specs. will be supported
!
