Unlock AES-NI in Phoenix

[carsalinas]

Hi,

I have 2 laptops of the same brand (vit.gob.ve) and model (P3400-002). The first one have the AES-NI option enable from factory (there is not menu or option in BIOS), and the second laptop doesnt have the AES-NI option enabled (there is not option in BIOS)

Please check the text files with the cpuid information of both laptops

There is 2 images of the main screen of both BIOS

Also I, attached the two bios fyi. I have been unable to flash the BIOS with the AES-NI enabled in the other laptop because I always get erros related to old version cannot be flashed in machines with newer BIOS.

As you said:

The first one have the AES-NI option enable from factory (there is not menu or option in BIOS), and the second laptop doesnt have the AES-NI option enabled (there is not option in BIOS)

So your task can't be solved by unlocking BIOS.

Hello,

Thanks for your repply. How can I transfer the OLD bios to the other machine? The software to make the firmware update always says: "Bios file is old" and stop the process.

But I think that BIOS downgrade will not help. Probably you need a hardware programmer to enable support for AES.
