You need to read bios chip with an external programmer and post your backup here. Otherwise we can´t help you.

But how to find this bios chip?

Do you have skills to repair a mainboard? In your case it's require to desoldering bios chip from the mainboard and programing the new file with one external spi programmer. If you can´t do this please asking for a shop in your area to accomplish the job..
