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 processors 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 200MHz or 266MHz DDR
SDRAM DIMMs.

The VT82C686B 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 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.
