The audio stream for the line-out port is routed according to the following
dependencies:
• By default, the audio stream is down-mixed to mono and amplified for an internal

mono speaker.

• If a connection is detected at the back panel line-out port, the audio stream is sent

to the rear line-out port and the internal mono speaker is disabled.

NOTE

The back panel audio line out connector is designed to power headphones or amplified
speakers only. Poor audio quality occurs if passive (non-amplified) speakers are
connected to this output.

Legacy Input/Output (I/O) Controller

The legacy I/O controller features the following:
• Two serial ports
• One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port

(EPP) support

• Serial IRQ interface compatible with serialized IRQ support for PCI systems
• PS/2-style keyboard interface
• Intelligent power management, including a programmable wake up event interface
• PCI power management support

Network Bootloader Support

The LAN subsystem supports the traditional Pre-Execution Environment (PXE) as well
as the open-source gPXE (

http://etherboot.org/

) network bootloaders.

gPXE is an open source network bootloader providing traditional PXE environment
compatibility and additional protocol support, such as TCP, HTTP, DNS and iSCSI.
Refer to

http://etherboot.org/

for further information.

System deployments where gPXE features are leveraged allow for diskless client
configurations, eliminating the power consumption, thermal, acoustic, and cost
disadvantages of having a local storage device per station.

NOTE

gPXE source code is available on the Intel

®

Express Installer Drivers DVD shipped with

the desktop board, as well as upon request.
