installed on the computer, you need to know the version of the system BIOS currently installed.
NOTE The BIOS initializes the operating system, determines how the computer will interact
with the hardware devices, and provides for information transfer among hardware devices,
including the time and date. The computer system BIOS is stored on the system ROM.
BIOS version information (also known as ROM date and System BIOS) can be displayed by pressing
fn+esc (if you are already in Windows) or by opening the Setup Utility.
To use the Setup Utility for displaying BIOS information:
1. Open the Setup Utility by turning on or restarting the computer, and then pressing f10 while the
“Press to enter Setup” message is displayed in the lower-left corner of the screen.
2. If the Setup Utility does not open with the system information displayed, use the arrow keys to
select the Main menu.
When the Main menu is selected, BIOS and other system information is displayed.
3. To exit the Setup Utility, use the arrow keys to select Exit > Exit Discarding Changes, and
then press
enter .
