Lenovo ThinkPad R61 BIOS firmware packed in a 829 KB ZIP archive. The name gives only the model, so no board number, revision or chip type is stated and the contents should be checked after extraction. Technicians use such dumps to recover a laptop with corrupted firmware by writing the image to the SPI flash with a hardware programmer. Read and save the original chip contents first, compare the image size to the chip capacity, and confirm the board matches the R61 before flashing anything.
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.
