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 an electrically erasable programmable read-only module (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 (see appendix a, “getting help and technical assistance” on page 93).

    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.
