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.
