Intel Desktop Board D915GVWB Technical Product Specification 1.8.4 Keyboard and Mouse Interface PS/2 keyboard and mouse connectors are located on the back panel. NOTE The keyboard is supported in the bottom PS/2 connector and the mouse is supported in the top PS/2 connector. Power to the computer should be turned off before a keyboard or mouse is connected or disconnected. For information about The location of the keyboard and mouse connectors Refer to Figure 15, page 46 1.9 Audio Subsystem The board supports the Intel High Definition audio subsystem based on the Realtek ALC860 codec. The audio subsystem supports the following features: • Advanced jack sense (front and rear panel) that enables the audio codec to recognize the device that is connected to an audio port. All jacks are capable of retasking according to user's definition, or can be automatically switched depending on the recognized device type. • Stereo input and output for all jacks. • A signal-to-noise (S/N) ratio of 90 dB. # INTEGRATOR'S NOTE For the front panel jack sensing and automatic retasking feature to function, a front panel daughter card that is designed for Intel High Definition Audio must be used. Otherwise, an AC '97 style audio front panel connector will be assumed and the Line Out and Mic In functions will be permanent. 1.9.1 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 15 1.9.2 Audio Connectors The board contains audio connectors on both the back panel and the component side of the board. The front panel audio connector (located on the component-side of the board) is a 2 x 5-pin connector that provides mic in and line out signals for front panel audio connectors.
