I am looking to install the Insyde 1.12 Unlocked BIOS for my Acer Aspire V3-771G, I currently have the stock version of the Insyde 1.12 BIOS installed, so I am unsure if I can actually install what amounts to the same BIOS, although unlocked, over it.

The stock BIOS can be installed directly from within Windows and also has a DOS installer as well, but I am not sure about the unlocked BIOS. Here is a screenshot of the files within the zip file for the unlocked BIOS:

The BIOS itself can be found for download here:


There are no instructions in the zip archive, which I think is just stupid!

Can anyone give me an idea of how to do this, because I assume there are people here who have installed unlocked BIOS in their PCs before?
