BIOS version 1.04 for the Acer Aspire A514-52K, on motherboard NB8517_MB_V2, packaged as a 4.80 MB RAR archive. The image is used to recover a board after a failed update or corrupted firmware, typically by writing it to the SPI flash with an external programmer, or through the vendor flash utility when the system still boots. Check that the board marking and the V2 revision on the PCB match, verify the extracted image size equals the chip capacity, and save a backup of the existing chip contents before writing.
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.
