BIOS and EC firmware package for the Dell Latitude E5520, from the Intel Krug 15 UMA board design at revision A01, which has integrated graphics only. Krug is the platform project name for this board. Use it to reflash the system BIOS SPI chip and the embedded controller firmware when a unit stays dead, beeps abnormally or fails to charge because the firmware is damaged. Read and keep the original contents first, and verify that the image size suits the chip and that the board is the UMA version.
