Mainboard BIOS for the Lenovo B570e built on the Wistron LZ57 project, provided as a 2.32 MB RAR archive with no board number or version stated in the name. Wistron boards carry a five-digit number with a dash revision on the PCB, which should be checked against any information inside the archive. Technicians write this kind of image to the SPI flash using a programmer to restore booting. Back up the original chip before writing and confirm the image size fits the flash device.
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.
