BIOS archive for the Dell OptiPlex 7020 minitower, 6.96 MB RAR, with the codes E93839 and AMO426 in the name; their meaning is not stated, though E93839 resembles a board marking, so compare them against the PCB before use. Technicians write such an image to the SPI flash with an external programmer to restore a board that fails to start. Save the original chip contents first, since they include the service tag, and confirm the extracted image size matches the flash chip before programming.
