III. HARDWARE SETUP
25. System Management Interrupt (SMI) Lead (2-pin SMI)
This allows the user to manually place the system into a suspend mode or "Green"
mode where system activity will be instantly decreased to save electricity and
expand the life of certain components when the system is not in use. This 2-pin
connector (see the figure below) connects to the case-mounted suspend switch.
If you do not have a switch for the connector, you may use the "Turbo Switch"
since it does not have a function. SMI is activated when it detects a short to open
moment and therefore leaving it shorted will not cause any problems. May
require one or two pushes depending on the position of the switch. The key-
board will always allow wake-up (the SMI lead cannot wake-up the system).
26. System Warning Speaker Connector (4-pin SPEAKER)
This 4-pin connector connects to the case-mounted speaker. You may leave this
disconnect as this motherboard has an onboard buzzer which can replace the
chassis speaker. When connected, you will hear system warnings though both
sources.
NOTE: Some sound cards allow you to connect to the system speaker signal so
that the warnings can be heard and adjusted through your multimedia system.
