MSI MS-6380 LE User manual

Introduction
1-1
The MS-6380 LE ATX mainboard is a high-performance computer
mainboard based on V A® Apollo KT266 chipset and designed for the
AMD® Athlon or Duron (PGA) processor for inexpensive business/
personal desktop markets.
The Apollo KT266 chipset consists of the VT8366 Super Northbridge
and the VT8233 Southbridge. VT8366 provides a PC1600/2100 DDR (Double
Data Rate) solution with support for 200/266MHz Front Side Bus. By using
PC2100 DDR technology, the VT8366 enables 2.1GB/second peak bandwidth
between system memory and Northbridge. The chipset doubles the commu-
nication bandwidth between the North and South Bridge to 266MB/sec
through a high-speed V-Link bus. With AGP 4X interface, VT8366 boosts
system performance for 3D graphics and video program.
The VT8233 Southbridge integrates many peripheral controllers
including dual channel UltraDMA-33/66/100 master mode E DE controller,
AC-link interface, LPC interface, USB controller etc. The VT8233 is compat-
ible with PC -2.2 specification and supports advanced power management.
The Apollo KT266 chipset provides the optimized performance for
the PC systems based on the latest AMD® processors.
