Chapter 6. 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 diskette 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)

diskette or an update program that can be run from the operating system.

Note: You can download a self starting bootable CD image (known as an .iso

image) of the diagnostics program from http://www.lenovo.com to support

systems without a diskette drive.

Updating (flashing) BIOS from a diskette or CD-ROM
