RAR archive containing a BIOS for the ASUS X555LD laptop, board revision 3.3 as indicated by RVE3.3, described in its name as fully working. At 17.7 MB it may hold more than a single image, so open it with WinRAR or 7-Zip and inspect the contents before choosing a file. Such dumps are written to the SPI flash chip with an external programmer to revive a board with a corrupted firmware. Match the revision on the PCB, back up the original chip and ensure the image size equals 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.
