Description
BIOS dump for Lenovo laptops, supplied for a 1 MB flash chip and packed as a 5.5 MB RAR archive. The original file name lists a family of models: V480, V580, V580c, V480c, B480, B580, M490, with the identifiers 1264 and U6001/U6002 in the name. Technicians use a dump like this to reprogram the SPI flash with a programmer after a corrupted BIOS or a failed update. Because the name covers several models, confirm that your exact model and board match before flashing, and save a backup of the original chip contents first.
