Chassis (2-pin)
This is for a chassis designed for chassis intrusion detection. After-market toggle switches
may also be installed to the chassis panel or any removable components. Two wires should
be available from the chassis to connect to this lead. When any chassis component is
removed, the contact should open and the motherboard will record a chassis intrusion event.
The event can then be processed by software such as LDCM. If the chassis intrusion lead is
not used, a jumper cap must be placed over the pins to prevent unnecessary power loss.
Speaker (4-pin)
It is used to drive a chassis-mounted speaker if desired.
Clear CMOS/Password (2-pin)
This jumper is used to clear CMOS setting. You can clear password or set all CMOS setting
to Default.
