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.
