hidden settings in bios InsydeH20 3.7

Hello, working unofficially a bit with electronics and computers maintenance, but I come here to get help.

Amazingly, but I have a Lenovo notebook s400 bios InsydeH20 3.7 (6DCN89WW (V8.03)).

Original manufactures, and somehow I made an involuntary sequence of keys and accessed the hidden settings.
 
but I can not access them again, was wondering if anyone could help me tested and which keys tighten again.
