BIOS dump for the Dell OptiPlex 980 desktop, taken from a Macronix 25L6445E-class 8 MB SPI flash as the name indicates, stored in a 2.67 MB RAR. A full chip image like this is used to recover a system that fails to POST after a corrupted update. Write it with an external programmer after reading and saving the original chip contents, since Dell dumps carry the service tag and ME data. Check that the image is exactly 8 MB before programming.
