BIOS for the Lenovo IdeaCentre B310 all-in-one computer, marked version 1.0, packed in a 584 KB zip archive. The small size suggests a compressed image or an update package rather than a full raw dump, so check the extracted file size against the flash chip before writing it with a programmer. Technicians use such firmware to revive an all-in-one that powers on without image or stalls at startup. Confirm the motherboard matches the B310 platform and keep a backup of the original chip contents, as it may store system identity data.
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.
