Desktop Board Features
The onboard audio headers include the following:
• Front panel audio (a 2 x 5 pin header that provides headphone and mic in signals
for front panel audio connectors)
• S/PDIF audio header (1 x 4 pin header)
Front panel headphone output is supported by a separate audio channel pair, allowing
multi-streaming audio configurations such as simultaneous surround sound playback
and stereo audio conferencing (through speakers connected to the back panel audio
connectors and a headset connected to the front panel audio connectors).
The onboard internal mono speaker header allows connection to an internal, low-
power speaker for basic system sound capability. The subsystem is capable of driving
a speaker load of 8 Ω at 1 W (rms) or 4 Ω at 1.5 W (rms).
The onboard S/PDIF header allows connection to coaxial or optical adapters for digital
audio output.
The back panel audio connectors are configurable through the audio device drivers.

• Intel 82579V Gigabit (10/100/1000 Mb/s) Ethernet LAN controller
• RJ-45 LAN connector with integrated status LEDs
LAN software and drivers are available at http://downloadcenter.intel.com/
.
Two LEDs are built into the RJ-45 LAN connector located on the back panel
(see Figure 2). These LEDs indicate the status of the LAN as shown in Table 3.
