BIOS dumps for the Dell Latitude E7240 on Compal board LA-9431P, in a 6.63 MB RAR archive. The U1 and U2 labels indicate images for two separate flash chips on the board, so each file must go to its matching location. Compal builds this Dell motherboard, as the LA number pattern shows. Use a programmer to read each chip, save the originals, then write the corresponding image. Confirm the board number on the PCB and that each file size matches the capacity of its chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
