BIOS configuration options.

Press <Esc> to move back to previous menu.
4.
To save changes, navigate to the
Save Changes and Exit
option from the main BIOS setting
menu to save setting changes and Exit. (You can also press F10 to save the setting and exit.)
Note:
Unless you are certain about the BIOS settings’ function, do not change system BIOS configuration.
Improper BIOS configuration can cause the VDX-6326 SBC fails to boot or function as expected.
