BIOS image for the Dell Latitude E7270, platform AAZ50, on the Compal LA-C451P motherboard at revision 1.0 (A00), compressed into a 7.83 MB rar. LA- numbers with a P suffix follow the Compal pattern, and Dell uses Compal for many Latitude boards. The dump is used to reprogram the SPI flash when the notebook shows no POST, a black screen or service tag problems. Back up the original chip, since the service tag and other system data live there, and confirm the flash capacity matches the image.
