Updating and recovering the BIOS
The BIOS is the first program that the computer runs when you turn on the computer. The BIOS initializes the
hardware components and loads the operating system and other programs.

the BIOS. You can update the BIOS from your operating system or a flash update disc (available only
on some models).
To update the BIOS, do the following:
1. Go to http://www.lenovo.com/support.
2. To update the BIOS from your operating system, download the flash BIOS update driver according to

version (used to create a flash update disc). Then, download the installation instructions for the flash
BIOS update driver.
