MSI K7T266 Pro, Pro-R, Pro-RU motherboard User manual

Introduction
Chapter 1.
Introduction
The K7T266 Pro (MS-6380) ATX mainboard is a high-performance
computer mainboard based on VIA® 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 communication 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 EIDE controller,
AC-link interface, LPC interface, USB controller etc. The VT8233 is compatible with PCI-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.

MSI Special Features
PC Alert™ III
The PC AlertTM III is an utility you can find in the CD-ROM disk. The
utility is just like your PC doctor that can detect the following PC hardware
status during real time operation:
* monitor CPU & system temperatures
* monitor fan speed(s)
* monitor system voltage
* monitor chassis intrusion
If one of the items above is abnormal, the program main screen will be immediately shown on the screen, with the abnormal item highlighted in red. This will
continue to be shown,until user disables the warning.
Note: Items shown on PC Alert III vary depending on your system’s status.

D-LED™
The D-LED™ uses graphic signal display to help
users understand their system. Four LEDs embedded in
the mainboard provide up to 16 combinations of signals to
debug the 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.
These users can use the feature to detect if there are any
problems or failures.
