Replace the battery with an equivalent one. Figure 1 on page 13 shows the location of the battery. 1.10 Legacy I/O Controller The I/O controller provides the following features: • Consumer Infrared (CIR) headers • Serial IRQ interface compatible with serialized IRQ support for PCI systems • Intelligent power management, including a programmable wake-up event interface • PCI power management support The BIOS Setup program provides configuration options for the I/O controller. 1.10.1 Consumer Infrared (CIR) The Consumer Infrared (CIR) feature is designed to comply with Microsoft Consumer Infrared usage models. Microsoft Windows Vista and Microsoft Windows 7 are the supported operating systems. The CIR feature is made up of two separate pieces: the receiving (receiver) header, and the output (emitter) header. The receiving header consists of a filtered translated infrared input compliant with Microsoft CIR specifications, and also a “learning” infrared input. This learning input is simply a high pass input which the computer can use to “learn” to speak the infrared communication language of other user remotes. The emitter header consists of two output ports which the PC can use to emulate “learned” infrared commands in order to control external electronic hardware. Customers are required to buy or create their own interface modules to connect to Intel Desktop Boards for this feature to work. Product Description 1.11 Audio Subsystem The board supports Intel HD Audio via the Realtek ALC892 audio codec. The 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. • A signal-to-noise (S/N) ratio of 97 dB • Microphone input that supports a single dynamic, condenser, or electret microphone • Windows Vista Ultimate and Windows 7 Ultimate certification Table 7 lists the supported functions of the front panel and back panel audio jacks.
