A 4 MB Dell firmware dump with an uninformative name that hints at a 15-inch model and a 32 Mbit Q32 type flash chip, with no file extension and no board number. Because the exact model is not stated, open it in a hex editor or BIOS tool to look for model and version strings before use. The size fits a 25Q32 class SPI chip. Confirm the board, back up the original chip with a programmer, and verify after writing.
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 →
