Chapter 1: Product Introduction
12. 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-denition front panel
audio module to this header to avail of the motherboard’s high-
denition audio capability.
• If you want to connect a high-denition 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].
13. 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.
14. 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.
15. Speaker header
The 4-pin header is for the chassis-mounted system warning speaker. The
speaker allows you to hear system beeps and warnings.
16. 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 certicates, passwords
and data. A TPM system also enhances network security,
protects digital identities, and ensures platform integrity.
The SPI TPM module is purchased separately.
