BIOS image for the G75VW motherboard in revision 2.2, packed as a 3.92 MB RAR. It differs from the Rev 2.1 dump for the same model, so the revision printed on the PCB decides which file applies. Technicians use it to restore corrupted firmware by programming the SPI chip directly with a hardware programmer. Read and store the original chip contents first, since they carry board-specific data, and confirm that the extracted image size matches the flash chip capacity.
