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 are 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.
System programs are stored in electrically erasable programmable read-only
memory (EEPROM) on the system board. This is sometimes referred to as flash
memory.
IBM occasionally makes changes and enhancements to the system programs.
When updates are released, they are available as downloadable files on the World
Wide Web. You can update system programs by starting your computer using a
flash update diskette or by using the Remote Administration feature, if it is enabled.
Instructions for using system programs updates are included in a readme file
provided with the downloadable files.
Shutting down your operating system
When you are ready to turn off the computer, use the shutdown procedure for your
operating system to save data and prevent damage to your applications. See your
operating-system manual for more information.
If you are using the preinstalled Microsoft Windows XP operating system, complete
the following steps to shut down your operating system and computer:
1. Save and close all files with which you are working.
2. Close all open applications.
3. Click the Windows start button.
4. Click Turn Off Computer ; then, click Turn Off to confirm.
Turning off the computer
When you turn off the computer and leave it connected to ac power, the computer
can respond to requests, such as a remote request to turn on the computer. To
remove all power from the computer, you must disconnect it from the power source.
Some operating systems require an orderly shutdown before you turn off the
computer. See your operating-system documentation for information about shutting
down the operating system.
