A BIOS dump for a Dell model given as 6520, most likely the Latitude E6520, with q32 probably marking a 32 Mbit chip, matching the 4 MB size. Boards of this generation can use two flash chips, so this may be only one of a pair. It is for programming with an SPI tool when a board will not boot. Check which chip on your board is 32 Mbit before writing, and read the original contents first so you can go back to them.
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 →
