Firmware set for the Dell Latitude E6420 on Compal board LA-6592P, containing BIOS, EC and IO data plus backups for an 8MB and a 2MB flash chip. The two images reflect the dual-chip layout on this board, so each must go to the chip of matching size. LA-6592P is a Compal number used by Dell. Read and save both originals before programming, since service tag and system data are stored there, and confirm the board number printed on the PCB matches the one named here.
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.
