Firmware image for a board identified as HUSK MB 11309-2, a 3.00 MB ZIP; Husk is the Wistron project name and 11309-2 the board number and revision. No laptop model is named, though Wistron builds boards for brands such as Acer. A file this size is typical of a full SPI flash dump, used to restore a dead or bricked board with a programmer. Read and keep the original chip contents before writing, and confirm both the board marking and the flash chip capacity match the image.
