Unlock BIOS package for the Lenovo ThinkPad T500, a 351 KB RAR archive aimed at removing a BIOS or supervisor password lock. The name does not say which chip the file targets or which BIOS version it came from, so check the archive contents and any notes inside before use. Technicians write such images with an external programmer once the original data has been read and saved. Compare the file size with the target chip capacity, since an image that does not match the chip will not flash correctly.
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 @biosarchive. Enginerys does not host this file.
