Working dump for the Dell Latitude E5440 from chip U1, a Winbond 25Q64FV 64 Mbit SPI flash, marked ok in the name. It forms one half of the dual-chip firmware layout, alongside the separate U2 25Q32FV image. After extracting the RAR, the binary should be 8 MB to match the chip. Keep a backup of the original U1 contents, which may carry the service tag. Program and verify with an external programmer, and make sure each image goes to its correct position.
