[Unlocked] Acer Aspire 5551

Hi,

Just wanted to report that camiloml's BIOS modification works for the Acer Aspire 5551, it reveals hidden menus.

I noticed that Acer's BIOS updates for both the 5551 and 5552 were identical, they even use the same identifier (BA/JE/HM/SJV5x-DN).

As has been reported though, there isn't any settings related to EFI functionality, it's sad as the BIOS is an EFI BIOS.

In the past I managed to obtain a dump of the EFI modules (..older version) using a python script written by someone else curious about customizing InsydeH20's UEFI firmware, sadly it's cumbersome and has a lot of hardcoded offsets.

Still, I wonder if it would be possible to add the reference EFI shell from the tianocore project? that would be a nice compromise, it would allow for further access to the EFI environment and potentially allow manually booting EFI/GPT aware operating systems.

Thanks camiloml, I appreciate what you've done, it would be nice if the procedure was documented somewhere.

P.S: Don't mess with the Video related settings on the Aspire 5551, one specific setting related to memory will force you to read the service guide and perform an emergency Fn+ESC flash.

Thanks for the info

ARGH.


Could ANYONE tell me what file name I need to use on the .fd file to run an emergency recovery? (the FN + esc function.)

I know you need to put the .fd file and the flash util on a drive, but I have no idea what to change the bios file name to and can't find anything on it.

PLEASE someone help me with this, as my laptop is currently bricked and i've only had it for a while

My laptop is the aspire 5551 athlon II x2 2.1ghz version.

I can find the file names for just about every [censored] machine EXCEPT the 5100.

have you tried BIOS.fd

Hi,
could you please confirm that the mod bios you linked works for the Acer Aspire 5551G too?
On the Acer official bios download site it seems that aspire 5551 and 5551G need the same bios but I'm not sure.
This is the link of the 2.14 bios ver. for the Acer 5551G, I hope it can help you to find out what I asked.
