BIOS is also used to identify and configure hardware components in a computer such as the hard drive, floppy drive, optical drive, CPU, memory, Plug and Play devices etc.
Incorrectly changing BIOS settings may leave the computer in a state in which the operating system no longer starts.
We recommend that you record the original BIOS settings before you modify them.
It is best to review the release notes to determine whether the update will benefit your system.
Also, review the instructions that are included with the BIOS update software, prior to performing an update.
