Firmware archive for the Lenovo IdeaCentre B310 all-in-one desktop, RAR format, 563 KB, with no BIOS version stated in the name. Open it to check the actual file type and size; a compressed archive this small may hold a BIOS image meant for a 1 MB or larger SPI chip. It is used to restore firmware on an all-in-one unit with a no-boot fault caused by a corrupted BIOS. Read and save the existing chip first, verify the mainboard matches the B310, and compare the image size with the chip capacity.
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.
