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.
When you install a new program, device driver, or hardware component, you might be informed to update
the UEFI BIOS. You can update the UEFI BIOS by starting your computer from a flash update disc or a flash
update program running in the Windows environment.
The requirements for flash update are as follows:
• The computer must be started over LAN.
• The computer must be engaged in the Preboot eXecution Environment (PXE).
• A network-management program must be installed on the computer of the network administrator.
For instructions on how to update the UEFI BIOS, go to http://www.lenovo.com/support.
