Speaker
The mainboard can drive an 8Ω external speaker at 0.5 watts. If
there is no external speaker, the SBC-776 provides an onboard
buzzer as an alternative.
LED interface
The front panel LED indicator for hard disk access is an active low
signal(24 mAsink rate).
Next you may want to install external switches to monitor and
control the mainboard. These features are completely optional —
install them only if you need them. The front panel connector (JP6)
is an 16-pin male, dual in-line header and provides connections for
a speaker, hard disk access indicator and an input switch for
resetting the card.

VGA connector (CN6)
The mainboard's PCI SVGA interface can drive conventional CRT
displays and is capable of driving a wide range of flat panel
displays, including electroluminescent (EL), gas plasma, passive
LCD, and active LCD displays. The board has two connectors to
support these displays, one for standard CRT VGA monitors and
one for flat panel displays.
VGAdisplay connector(CN6)
CN6 is a 15-pin, dual-in-line header used for conventional CRT
displays. A simple one-to-one adapter can be used to match CN6 to
a standard 15-pin D-SUB connector commonly used for VGA.
