D-Led™ & D-Bracket - MSI 845 Pro Manual

Chapter 1
D-LED™ & D-Bracket™
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.
If your motherboard supports and installs D-
Bracket™ which also integrates four Diagnostic LEDs, definitions of the
LED signals are the same as D-LED™ as shown below.
