Desktop Board Features 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. 17
