Tested firmware dump for the Dell OptiPlex 3046 in its M (micro) form, in a ZIP archive of about 4.9 MB. It serves as a known good reference when the system board will not post or hangs after a bad BIOS update. Writing is done with an SPI programmer clipped onto the flash chip. Read the existing contents first, because Dell firmware regions can carry the machine's service tag and configuration. Make sure the image size fits the fitted chip and that the board really comes from a 3046M.
