Gigabyte GA-7PESH2 BIOS.bin file?

Hi All am new here and overall new at this re flashing process. I have a bricked ga-7pesh2 board; I purchased the board as is and the previous owner tried to flash the BIOS by removing it and re-soldering it, however this fail and the chip was damaged. I have a replacement blanked bios chip but I can’t find the BIN file. I tried to extracted file from the Gigabyte site bios download, but the file seems to be missing part of the programing. Any ideas? Thanks in advance for any advices.
