I need to modify my system's BIOS settings but the items are not selectable and there is a message on the right that says "BIOS cannot be modified in user mode. If items require change please consult your system supervisor." I am the system supervisor, how do I enter "system suervisor' mode so that I can make the changes I need to make? Is there a way to make changes in BIOS from Windows (7)? I am particularly interested in changing my fingerprint reader, which somehow got changed to external, to internal but there are also other settings I would likt to adjust. Thank you in advance for any assistance you provide me.
