D-Bracket™ & D-Led™ (Optional) - MSI MS-6528LE User Manual

Chapter 1
D-Bracket™ & D-LED™ (Optional)
The D-LED™ uses graphic signal display to help us-
ers understand their system. Four LEDs embedded in the
mainboard provide up to 16 combinations of signals to de-
bug 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.
Definitions of the D-Bracket™ LED signals are the same as D-LED™ as shown
below.
