12. Chassis intrusion header
This header is for a chassis-mounted intrusion detection sensor or switch.
Connect one end of the chassis intrusion sensor or switch cable to this
connector. The chassis intrusion sensor or switch sends a high-level signal to
this connector when a chassis component is removed or replaced. The signal
is then generated as a chassis intrusion event.
13. Intel
®
ME jumper
This jumper allows you to enable or disable the Intel
®
ME function. Set this jumper to pins 1-2
to enable (default) the Intel
®
ME function and to pins 2-3 to disable it.
Disable the Intel
®
ME function before updating it.
14. COM Port headers
These headers are for serial (COM) ports. Connect the serial port module cable to any of
these headers, then install the module to a slot opening at the back of the
system chassis.
15. Front panel audio header
This header is for a chassis-mounted front panel audio I/O module that
supports HD audio standard. Connect one end of the front panel audio I/O
module cable to this header.
•
We recommend that you connect a high-definition
front panel audio module to this header to avail of the
motherboard’s high-definition audio capability.
•
If you want to connect a high-definition front panel audio
module to this header, set the Front Panel Type item in
the BIOS setup to [HD Audio]. By default, this header is
set to [HD Audio].
16. LPC Debug header
