BIOS dump for the Dell OptiPlex 3060 small form factor desktop with mainboard 17539-1, marked as tested and working, packed in a 6.66 MB RAR archive. The 17539-1 number follows the Wistron pattern, so the board was built by Wistron for Dell. Use it to reprogram the SPI flash after a failed update or when the system does not post. Back up the original chip first because it holds the service tag. Check the board number on the PCB and confirm that the extracted image size matches 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 @hrtechno. Enginerys does not host this file.
