12. COM Port header
This header is for a serial (COM) port. Connect the serial port module cable to
this header, then install the module to a slot opening at the back of the system
chassis.
13. 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].
14. LPT header
The LPT (Line Printing Terminal) header supports devices such as
a printer. LPT standardizes as IEEE 1284, which is the parallel port
interface on IBM PC-compatible computers.
15. S/PDIF Out header
This header is for an additional Sony/Philips Digital Interface (S/PDIF) port.
Connect the S/PDIF Out module cable to this header, then install the module to
a slot opening at the back of the system chassis.
16. Speaker header
The 4-pin header is for the chassis-mounted system warning speaker. The
speaker allows you to hear system beeps and warnings.
17. SPI TPM header
This header supports a Trusted Platform Module (TPM) system with a
Serial Peripheral Interface (SPI), allowing you to securely store keys, digital
certificates, passwords, and data. A TPM system also helps enhance
network security, protects digital identities, and ensures platform integrity.
