BIOS image for the Dell OptiPlex 5050 desktop, a raw 16.0 MB binary that corresponds to a full 16 MB SPI flash. A dump like this is used when the system does not post, hangs on the Dell logo or was interrupted during an update. Write it with an external programmer after reading and saving the original chip, since a full dump may carry another unit's service tag and ME data. Confirm the chip on your board is 16 MB and that the board matches the 5050 model.
