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.

When you install a new program, hardware device, or device driver, you might be informed to update 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

your operating system version. To update the BIOS from a flash update disc, download the ISO image
version (used to create a flash update disc). Then, download the installation instructions for the flash
BIOS update driver.
