BIOS binary for the Dell Studio XPS 1645, intended for the Quanta board marked DARM5CMB8D1 at revision D. The 1.38 MB ZIP holds the image a technician writes to the SPI flash with a programmer when the laptop powers on without display or the firmware is damaged. Quanta numbering separates revisions by a final letter and digit, so compare this with the label on your board, since a rev E board may need a different file. Always dump and keep the existing contents before erasing the chip.
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 @biosarchive. Enginerys does not host this file.
