BIOS firmware for Dell Vostro 3468 and 3568 laptops at version 3.11, packed into a 5.45 MB RAR archive. Both models share the same BIOS, so one image serves either machine. Depending on the contents, it may be an official update package or a raw dump for writing straight to the SPI chip with a programmer, so check the files before use. When programming directly, save the existing chip contents first, since Dell keeps the service tag and system data there, and confirm the image size fits 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.
How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
