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.
