BIOS firmware for the Lenovo V480c laptop, packed as a 4.80 MB RAR archive. The name gives no motherboard number or revision, so read the board label before using it and compare with the chip markings. Such dumps are used to reprogram the SPI flash chip with an external programmer when the existing firmware is corrupted or the board fails to start. Always read and store the current chip contents first, and make sure the image size matches the capacity of the flash chip on your board.
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.
