system. In order to hear audio, you must connect one of these external devices
to the Audio Line-Out port on your computer.
Note: The internal speaker in your computer is disabled when an external
speaker is connected to the Line-Out port on your computer. There is no
playback capability through the internal speaker.
Ÿ
Audio Line In: This port is used to send audio signals from an external device
(such as a CD player or stereo) to your computer so that the signals can be
recorded on the hard disk. (However, you must go into the mixer provided in
your operating system and reduce the input level accordingly.)
Ÿ
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. The Configuration/Setup Utility Program
enables you 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 information, the BIOS code, and the Configuration/Setup Utility Program by
starting your computer using a flash update diskette or by using the Remote
Administration feature, if enabled.
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 109). Instructions for using the system programs updates are
available in a README file included in the download files.
