Unlocked BIOS image for board 213105-2, a raw 32.0 MB BIN file whose name indicates it was derived from a dump with an old admin password and then unlocked. The 6-digit dash-revision number follows Wistron's pattern, though the laptop brand is not given. A 32 MB image fits a 256 Mbit SPI flash chip, so confirm your chip matches before programming. Use it to clear a supervisor password by writing it with an SPI programmer, keeping a backup of the original chip for serial and system data.
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 @smbiossupport. Enginerys does not host this file.
