Updating your system 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.
