Note: The internal speaker in your computer is disabled when an external speaker is connected to the headphone port on your computer. Audio Line Out: This jack is used to send audio signals from the computer to external devices, such as stereo-powered speakers with built-in amplifiers, headphones, multimedia keyboards, or the Audio Line-In jack on a stereo system. Microphone: This port is used to connect a microphone to your computer when you want to record voice or other sounds on the hard disk. This port can also be used by speech recognition software. Note: If you experience interference or speaker feedback while recording, try reducing the microphone recording volume (gain). Procedures for recording and playing back sound vary by operating system. Refer to your operating system documentation for information and instructions. Updating System Programs System programs are the basic layer of software built into your computer. They include the power-on self-test (POST), the basic input/output system (BIOS) code, and the Configuration/Setup Utility Program. POST is a set of tests and procedures that is performed each time you turn on your computer. BIOS is a layer of software that translates instructions from other layers of software into electrical signals that the computer hardware can understand. You can use the Configuration/Setup Utility Program to view and change the configuration and setup of your computer. Your computer system board has a module called electrically erasable programmable read-only memory (EEPROM, also referred to as flash memory). You can easily update POST, BIOS, and the Configuration/Setup Utility Program by starting your computer using a flash update diskette or by using the Remote Administration feature, if enabled. See "Setting Remote Administration" on page 36 for more information. As part of the continuing work to improve quality, IBM might make changes and enhancements to the system programs. When updates are released, they are available as downloadable files on the World Wide Web or through the PC Company Bulletin Board Service (see Chapter 9, "Getting help, service, and information" on page 121). Instructions for using the system programs updates are available in a README file included in the update files. 22 PC 300GL User Guide
