Hello, I was wondering if someone could unlock this BIOS.

Thanks! I am going to do it as soon as I can.

EDIT: I've tried to update to one of the latest bios that I linked in the first post but it keeps saying: 3 - Error: ROM file size does not match existing BIOS size.

...so I've dumped my actual bios.

As I've already said in the previous post: I've tried to update to one of the latest bios that I linked in the first post but it keeps saying: 3 - Error: ROM file size does not match existing BIOS size.

By your dump bios, it explain the bios chip size is 4mb on your motherboard ,but the attachment from your post#1 it should for a 8mb chip size ,so shown this message is very normal and correct.

Sometimes the same motherboard model has different pcb version and different size of bios chip is normal.

================
Try this modded.

This is the modded bios as it appears: Imgur

The forum doesn't let me attach more than five files so I hosted everything on imgur.

EDIT: I have now two "Main" and two "Advanced" sections, as you can see in the pictures

Yes ,it's right.
There are three new tabs appear in bios screen ,they are "Main","Advanced" and "chipset".
Main tab show more information ,most of features are contained at Advanced and Chipset tab ,so i choose unlocked them.

Thanks for your reply.
