4-38 Chapter 4: BIOS Setup
Exit & Discard 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.
Discard Changes
This option allows you to discard the selections you made and restore the
previously saved values. After selecting this option, a confirmation
appears. Select Yes to discard any changes and load the previously saved
values.
Load Setup Defaults
This option allows you to load the default values for each of the
parameters on the Setup menus. When you select this option or if you
press <F5>, a confirmation window appears. Select Yes to load default
values. Select Exit Saving Changes or make other changes before
saving the values to the non-volatile RAM.
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. Press <Enter> to save the changes
while exiting.
Exit & Save 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.
