Raw 8 MB BIOS binary for Wistron board 13269-1, labelled as tested; the laptop brand and model are not stated. Wistron uses the five-digit number with a dash revision, and many Dell boards carry this format. An 8 MB image matches a 64 Mbit SPI flash chip, so check the chip part number before writing. Use a programmer such as a CH341A, read and save the original chip first, then write and verify. Make sure 13269-1 is printed on your board before you use it.
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 @ITHINKHS. Enginerys does not host this file.
