Firmware package for an X270 laptop in which the BIOS password has been removed, according to the name, supplied as a 5.50 MB ZIP containing a binary image. Such a dump is written directly to the SPI flash chip to clear a supervisor password lock without the original credentials. Before programming, dump and keep the existing chip contents, because they hold serial number and platform data. Check that the board in hand matches the X270 and that the image size corresponds to the chip capacity, otherwise it will not fit.
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 @biosfilebins. Enginerys does not host this file.
