Patched backup of a ThinkPad X240 BIOS, stored as a 5.56 MB RAR archive. The name says the original dump was modified but does not say what was changed, so the patch could involve the ME region, passwords or other settings. Treat it with care and keep your own untouched chip read before writing it to the SPI flash with a programmer. Confirm that the file size matches the chip capacity, and test the board fully after flashing.
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.
