BIOS firmware for the Intel DQ67SW desktop motherboard, an Intel-branded board based on the Q67 chipset, as the model code indicates, stored as a 4.72 MB ZIP. The name states no version or flash chip type, so open the archive to see whether it holds a raw SPI image or an Intel update file. A raw dump is programmed onto the BIOS chip with an external programmer to recover a board that no longer posts. Back up the existing contents first. Make sure the dump matches the chip size and keeps any board-specific data intact.
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 .zip file
Compressed archive that every operating system opens without extra software.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
