Speaker Connector
An offboard speaker can be installed on the motherboard as a manufacturing
option. An offboard speaker can be connected to the motherboard at the front
panel connector. The speaker (onboard or offboard) provides error beep code
information during the Power On Self-Test when the computer cannot use the
video interface. The speaker is not connected to the audio subsystem and does not
receive output from the audio subsystem.
Reset Button
This connector can be connected to a momentary SPST type switch that is
normally open. When the switch is closed, the motherboard resets and runs the
POST.
Power LED Connector
This connector can be connected to an LED that will flashing when the computer
is sleeping.
Hard Drive LED Connector
This connector can be connected to an LED to provide a visual indicator that data
is being read from or written to a hard drive. For the LED to function properly, an
IDE drive must be connected to the onboard hard drive controller.
Infrared Connector
After the IrDA interface is configured, files can be transferred from or to portable
devices such as laptops, PDAs, and printers using application software.
Green (Sleep/Resume) Switch
When APM is enabled in the system BIOS, and the operating system’s APM
driver is loaded, the system can enter sleep (standby) mode in one of the
following ways:
•
Optional front panel SMI button
•
Prolonged system inactivity using the BIOS inactivity timer feature
The 2-pin header located on the front panel I/O connector supports a front
panel SMI switch, which must be a momentary SPST type that is
normally open.
Closing the SMI switch sends a System Management Interrupt (SMI) to
