Using system programs

System programs are the basic layer of software built into your computer. System programs include the
POST, the BIOS, and the Setup Utility program. The POST is a set of tests and procedures that are
performed each time you turn on your computer. The BIOS is a layer of software that translates instructions
from other layers of software into electrical signals that the computer hardware can execute. You can use the
Setup Utility program to view or change the configuration settings of your computer. See "Using the Setup
Utility program" on page 59 for detailed information.
The system board of your computer has a module called electrically erasable programmable read-only
memory (EEPROM, also referred to as flash memory). It enables you to update the POST, the BIOS, and
the Setup Utility program easily. To perform such an update, you can either start your computer with a
system-program-update disc or run a special update program from your operating system.
Lenovo might make changes and enhancements to the POST and BIOS. When updates are released, they
are available as downloadable files on the Lenovo Web site at http://www.lenovo.com. Instructions for using
the POST and BIOS updates are available in a TXT file that is included with the update files. For most
models, you can download an update program that can be used to create a system-program-update disc
or be run from the operating system.
