Raw 16 MB binary named after the Winbond W25Q128BV, a 128 Mbit SPI flash chip, with a note about a BIOS lock. The name does not identify the laptop or board, so its origin is unknown. The lock note may mean the image removes or contains a BIOS password or lock, but this cannot be confirmed from the name. Write it with a programmer only after identifying the board it came from, and always read and keep the original chip contents first. The 16 MB size matches a 128 Mbit part.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @free_bios_support. Enginerys does not host this file.
