FCC-BRadioFrequencyInterferenceStatement
This equipment has been tested and found to comply with the limits for a class
B digital device, pursuant to part 15 of the FCC rules. These limits are designed
to provide reasonable protection against harmful interference when the equip-
ment is operated in a commercial environment. This equipment generates, uses
and can radiate radio frequency energy and, if not installed and used in accor-
dance with the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is likely to
cause harmful interference, in which case the user will be required to correct
the interference at his own expense.
Notice 1
The changes or modifications not expressly approved by the party respon-
sible for compliance could void the user’s authority to operate the equipment.
Notice 2
Shielded interface cables and A.C. power cord, if any, must be used in order to

Chapter 1. Introduction
The K7T266 Pro2 (MS-6380 v2.X) series ATX mainboards are high-
performance computer mainboards based on VIA®Apollo KT266A
(VT8366A & VT8233) chipset and designed for the AMD®Athlon™,
Athlon XPor Duron™ (PGA) processor for inexpensive business/personal
desktop markets.
Four models are available for K7T266 Pro2 series motherboards.
They are K7T266 Pro2,K7T266 Pro2-R,K7T266 Pro2-U and K7T266
Pro2-RU. K7T266 Pro2 is the standard version. In addition to standard
features, K7T266 Pro2-R adds support for IDE RAID function, while K7T266
Pro2-U does not support IDE RAID function, but comes with support for the
newest high-bandwidth USB 2.0 technology. The model, K7T266 Pro2-RU,
not only supports USB 2.0 function but also integrates IDE RAID technol-
ogy on the board.
These models provide rich flexibility in meeting consumers’ diverse
needs for VIA®Apollo KT266A-based motherboards.

PC Alert™ III
The PC AlertTM III is a 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 listed above is abnormal, the program main screen will be
immediately shown on the screen, with the abnormal item highlighted in red.
This screen will continue to be shown,until user disables the warning.
MSI Special Features
Note: Items shown on PC Alert III vary depending on your system’s status.

D-LED™ (Optional)& D-Bracket™
Red Green
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.
The D-Bracket™, which integrates four Diagnostic LEDs, is optional.
The definitions of the D-Bracket™ LED signals are the same as D-LED™.
