Compressed 12.4 MB 7z image tied to board number 213264-1, which follows Wistron's numbering, with no laptop brand or model named. The outimage label suggests a programmer output dump, but the name does not confirm whether it is a full SPI image or a single region. Extract it and compare the BIN size with your flash chip capacity, since a mismatched image will not fit. Wistron builds boards for Dell, HP, Acer and others, so verify the number on the PCB and back up the original chip first.
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 @efibios. Enginerys does not host this file.
