Chapter 9. Updating system programs
This chapter provides information about updating the POST and BIOS, and how to recover from a POST
and BIOS update failure.
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 Chapter 7
“Using the Setup Utility program” on page 77 for detailed information.
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 the POST, the BIOS, and the Setup
Utility program by starting your computer with a system-program-update disc or running 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/support. 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 either an update program to create a system-program-update disc or an
update program that can be run from the operating system.
Updating (flashing) the BIOS from a disc
This section provides instructions on how to update (flash) the BIOS from a disc.
Note: You can download a self-starting bootable disc image (known as an ISO image) with the system
program updates to create a system-program-update disc. Go to http://www.lenovo.com/support.
To update (flash) the BIOS from a disc on the Windows 8 (64-bit) or Windows 8.1 (64-bit) operating system,
do the following:
1. Start the Setup Utility program. See “Starting the Setup Utility program” on page 77.

window opens, release F12.
6. From the Startup Device Menu window, select the desired optical drive as the startup device. Then,
insert the disc into this optical drive and press Enter. The update begins.
