Asus Motherboard NR-LSR - Manual (Page 80)

4-28 Chapter 4: BIOS Setup
4.8 Exit Menu
When you have made all of your selections from the various menus in the
Setup program, save your changes and exit Setup. Select Exit from the
menu bar to display the following menu.
Exit Saving Changes
Once you are finished making your selections, choose this option from the
Exit menu to ensure the values you selected are saved to the CMOS RAM.
The CMOS RAM is sustained by an onboard backup battery and stays on
even when the PC is turned off. When you select this option, a
confirmation window appears. Select [Yes] to save changes and exit.
Pressing does not immediately exit this menu. Select one of the
options from this menu or from the legend bar to exit.
If you attempt to exit the Setup program without saving your changes,
the program prompts you with a message asking if you want to save
your changes before exiting. Pressing saves the changes
while exiting.
Exit Discarding Changes
Select this option only if you do not want to save the changes that you
made to the Setup program. If you made changes to fields other than
system date, system time, and password, the BIOS asks for a confirmation
before exiting.
