A firmware dump for the Dell Latitude E6430, with q64 in the name probably marking the 64 Mbit chip, which matches the 8 MB size. The E6430 often uses two SPI flash chips, and a companion 32 Mbit image appears to exist separately, so make sure this file goes onto the 64 Mbit part. Write it with a hardware programmer and keep the original contents. Confirm the chip markings on the board before erasing, because swapping the two images will stop the board from booting.
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 @biosfilebins. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
