as downloadable files on the Lenovo Web site at http://www.lenovo.com/drivers. Instructions for using the
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.
This chapter provides information about updating the BIOS, and how to recover from a BIOS update failure.
