BIOS dump for the Dell OptiPlex 3080 tower desktop, motherboard 18463-1, labelled as tested. The 8.25 MB RAR archive contains the SPI flash image used to recover a desktop that powers on without video or is stuck after a failed update. Numbers in the 18463-1 style follow the Wistron pattern, the ODM that builds many Dell boards. Match the board number before writing, keep a backup of the original chip, and make sure the image size equals the chip capacity, since a mismatched file will not fit.
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 @generalbios. Enginerys does not host this file.
