SPK (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.
RST (Reset Button)
This connector can be attached to a momentary SPST switch. This
switch is usually open and when closed will cause the motherboard to
reset and run the POST (Power On Self Test).
