Introduction
The MS-6341 ATX mainboard is a high-performance computer
mainboard based on AMD®761 chipset and VT82C686B. The MS-6341 is
designed for the AMD®Duron & Thunderbird processor for inexpensive
business/personal desktop markets.
The AMD-761 system controller features the AMD Duron system
bus, system memory controller, accelerated graphics port (AGP) controller,
and peripheral component interconnect (PCI) bus controller. The AMD-761
system controller is also designed to support 266-MHz DDR SDRAM
DIMMs.
The VT82C686B integrates all system control functions such as ACPI
(Advances Configuration and Power Interface). The ACPI provides more
Energy Saving Features for the OSPM (OS Direct Power Management)
function. The VT82C686B chipset also improves the IDE transfer rate by
supporting Ultra DMA-33/66/100 IDE that transfers data at the rate 33/66/
100MB/sec.

MSI Special Features
The MSI special features are designed by MSI R&D that can be seen
only in MSI mainboards. The 6341mainboard is equipped with PC AlertTM III ,
T.O.P TechTM III and D-LEDTM.
T.O.P TechTM.
The T.O.P TechTM is a extended sensing device that can 100% accu-
rately detect the CPU’s temeprature. You can know the temperature on BIOS
setup menu. The PC AlertTM also can provide the information.

PCAlertTM III
The PC AlertTM III is a utility you can find in the CD-ROM. The utility
is just like your PC doctor that can detect the following PC hardware status
during real time operation:
* monitor CPU & system temperature
* monitor fan speed
* monitor system voltage
* monitor chassis intrusion
If one of the items above is abnormal, the program main screen will be imme-
diately shown on the screen, with the abnormal item highlighted in red. This
will continue to be shown,until user disables warning.

The D-LEDTM uses graphic signal display to
help you understand your system. There are 4 LEDs
embedded in the mainboard which provides up to
16 combination of signals to debug system. The 4
LEDs can debug all problems that fail the system,
such as VGA, RAM or other failures. This special feature is very useful for the
overclocking users. The users can use this feature to detect if there are any
problems or failures while doing the overclocking.
