BIOS unlock & SLICslic 2.1 and ( UNLOCKED BIOS FOR ACER ASPIRE 7520 & 7220 & 5520 )

[mbmalone]

The Bios Unlock and SLIC 2.1 did NOT work on my ACER ASPIRE 7520. The hidden menu's unlocked, but SLIC 2.1 did not. I have tried several times. The SLIC 2.0 to SLIC 2.1 Upgrade worked, but I lost my unlocked hidden menus

I`m so sorry for my late response , my final exams has started and i was preparing for it before it begins .
However i`m so busy in my exams but i have found some time for your bios
Here is your modified bios :-
Unlocked all hidden options & Added SLIC2.1 .
You will find the Certificate inside the attached file .



This BIOS is only valid for ACER 7520 , 5520 and 7220 .
I will change the thread name for adding 7520 & 7220 .

Try it and i`m waiting your reply .

Does not work. Does not run.

Works like a charm on an Aspire 5520G Ahmed with instructions from: https://www.bios-mods.com/bios-update/. You know if there's any pages to be unlocked that enable configuring the memory speed/timings? My memory is running slower than it should, probably not detected well.
