Working BIOS dump for Dell Vostro 3670 and 3070 desktops built on board 17529-1, packed as a 7.6 MB RAR archive. The 17529-1 number follows Wistron numbering, identifying Wistron as the board ODM. The image is used to reprogram the SPI flash when a system fails to post or after a bad update. Save the original contents with a programmer before writing, since they hold the service tag and other unique data, and confirm the chip size and the PCB number match the file.
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.
