Firmware dump for an Acer laptop using the Wistron HUSK motherboard, board number 11309-2, with the extra code 4TU05 noted in the name, probably a PCB or part identifier. The 2.79 MB zip is smaller than the related V5-471 package, so it likely holds just the SPI image. Technicians use such a dump to recover a board that will not post or has a corrupted BIOS. Verify the board number on the PCB, back up the existing chip contents first, and make sure the file size equals the flash chip capacity before writing.
