Unlock hidden menus on Thinkpad Edge E145

Hi all,

I'm trying to unlock my bios, to enable hidden settings. I hope to be able to perform overclocking on my Laptop (Thinkpad Edge E145).
I have a Phoenix BIOS Menu called "Config", and under there "Serial SATA (SATA)", "Beep and Alarm" and some more, sub-menu's. However, I am unable to
find these strings in the extracted BIOS files.

So I tried to find interesting strings by random, and found these:
SpeedStep (<-- however this is Intel technology?)
CoreMultiProcessing
CPUPowerManagement
LenovoHiddenSetting
LenovoSecurityConfig
AMDSetup
AMDSetup2
LenovoSecurityConfig
AMD_cpm_setup
LenovoConfig

Then I found this interesting code:

lea rcx, aLenovohiddense ; "LenovoHiddenSetting"
mov qword ptr [rbp+7Fh], 22h
call qword ptr [rax]
test rax, rax
js loc_A3B

I think by forcing this jump, I might enable this sub-menu. However, its very new to me and I do not want to brick my BIOS.. Can someone tell me if I'm on the right track, or perhaps help me with unlocking my BIOS?

Here's my BIOS file: http://rghost.net/58665878
