Updating the UEFI BIOS
The UEFI BIOS is the first program that the computer runs when the computer is turned on. The UEFI BIOS
initializes the hardware components, and loads the operating system and other programs.
You can update the UEFI BIOS by starting your computer from a flash update optical disc or a flash update
program running in the Windows environment. When you install a new program, a device driver, or hardware,
you might be informed to update the UEFI BIOS.

Using system management
This topic is primarily intended for the network administrators.
Your computer is designed for manageability, so that you can redirect more resources to better meet
your business objectives.
This manageability, known as Total Cost of Ownership (TCO), enables you to remotely operate client
computers in the same way as you operate your own computer, such as turning on a client computer,
formatting a hard disk drive, and installing a program.
Once the computer is configured and operational, you can manage it by using the software and the
manageability features that are already integrated into the client computer and the network.
