manual abstract
Native mode is the preferred mode for configurations using the Windows* XP, Windows Vista*, and Windows 7* operating systems. For more information, see: For information about Refer to The location of the SATA connectors Figure 10, page 39 1.10 Legacy I/O Controller The Legacy I/O Controller provides the following features: • One serial port • One parallel port with Extended Capabilities Port (ECP) and Enhanced Parallel Port (EPP) support • Serial IRQ interface compatible with serialized IRQ support for PCI Conventional bus systems • PS/2-style keyboard/mouse interface • Intelligent power management, including a programmable wake-up event interface • PCI Conventional bus power management support The BIOS Setup program provides configuration options for the Legacy I/O controller. 1.10.1 Serial Port The serial port is implemented as a 10-pin header on the board. The serial port supports data transfers at speeds up to 115.2 kbits/s with BIOS support. For information about Refer to The location of the serial port header Figure 10, page 39 Product Description 1.10.2 Parallel Port The parallel port is implemented as a 26-pin header on the board. Use the BIOS Setup program to set the parallel port mode. For information about Refer to The location of the parallel port header Figure 10, page 39 1.11 Audio Subsystem The board supports Intel High Definition Audio via the Realtek ALC888S audio codec. The ALC888S-based audio subsystem supports the following features: • Advanced jack sense for the back panel audio jacks that enables the audio codec to recognize the device that is connected to an audio port. The back panel audio jacks are capable of retasking according to the user’s definition, or can be automatically switched depending on the recognized device type. • Stereo input and output via back panel jacks • Headphone and Mic in functions for front panel audio jacks • A signal-to-noise (S/N) ratio of 90 dB 1.11.1 Audio Subsystem Software Audio software and drivers are available from Intel’s World Wide Web site. For information about Refer to Obtaining audio software and drivers Section 1.3, page 14 1.11.2 Audio Connectors and Headers The board contains audio connectors and headers on both the back panel and the component side of the board. The component-side 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) (yellow) • S/PDIF audio header (1 x 4-pin header) (yellow) • Internal mono speaker header (1 x 2 pin header) (yellow) For information about Refer to The locations of the front panel audio header, S/PDIF header, and Figure 10, page 39 internal mono speaker header The signal names of the front panel audio header Table 14 and Table 15, page 42 The signal names of the S/PDIF header Table 12, page 42 The signal names of the internal mono speaker header Table 13, page 42 The back panel audio connectors Section 2.2.1, page 38 Intel Desktop Board DH55PJ Technical Product Specification 1.11.2.1 Analog Audio Connectivity The available configurable back panel audio connectors are shown in Figure 4. Item Description A Audio line in B Audio line out C Mic in Figure 4. Back Panel Audio Connector Options The back panel audio connectors are configurable through the audio device drivers. For information about Refer to The back panel audio connectors Section 2.2.1, page 38 The front panel headphone output is supported via a separate audio channel pair allowing multi-streaming audio configurations such as simultaneous 5.1 surround playback and stereo audio conferencing (through back panel speakers and front panel headset, respectively). 1.11.2.2 SPDIF Connectivity The SPDIF header allows connectivity to coaxial or optical dongles for digital audio output. 1.11.2.3 Internal Mono Speaker Connectivity The internal mono speaker header allows connectivity to an internal, low-power speaker for basic system sound capability. The subsystem is capable of driving a target speaker load of 8 Ohms at 1 W (rms) or 4 Ohms at 1.5 W (rms). Product Description 1.12 LAN Subsystem The LAN subsystem consists of the following: • Intel 82578DC Gigabit Ethernet Controller (10/100/1000 Mbits/s) • RJ-45 LAN connector with integrated status LEDs For information about Refer to LAN software and drivers 1.12.1 Intel® 82578DC Gigabit Ethernet Controller The Intel 82578DC Gigabit Ethernet Controller supports the following features: • 10/100/1000 BASE-T IEEE 802.3 compliant • PCI Express link • Compliant to IEEE 802.3x flow control support • 802.1p and 802.1q • TCP, IP, and UDP checksum offload (for IPv4 and IPv6) • Transmit TCP segmentation • Full device driver compatibility • PCI Express power management support 1.12.2 LAN Subsystem Software LAN software and drivers are available from Intel’s World Wide Web site.
