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 diskette or 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 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 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 ISO image) of the diagnostics program to support systems without a diskette drive from: http://www.lenovo.com Updating (flashing) BIOS from a diskette or disc This section provides instructions on how to update (flash) BIOS using a diskette or disc. System program updates are available at: http://www.lenovo.com/support 1.
