How to unlock the hidden settings of our BIOS

Some laptops and mini PCs with AMD processors come with locked BIOS options, let’s see how to access them easily.

With BIOS options we can increase or decrease the speed of our processor, also assign more RAM to the integrated GPU or change other important parameters. Many manufacturers lock these features so that users do not go beyond the design limits of the device, so we have to be careful what we change.
