Chapter 5. Updating system programs

This chapter contains information about updating POST/BIOS and how to recover
from a POST/BIOS update failure.

Using 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 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 execute. You can use the 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 Setup Utility program by starting your
computer using a flash update disc or by running a special update program from
your operating system.
Lenovo might make changes and enhancements to the POST/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/BIOS updates are
available in a TXT file that is included with the update files. For most models, you
can download either an update program to create a system-program-update (flash)
disc or an update program that can be run from the operating system.
Note: You can download a self starting bootable CD/DVD image (known as an
