Firmware archive for the Dell Latitude D420 on Compal board LA-3071P, about 662 KB in RAR form. The LA-xxxxP code is Compal's board numbering, identifying the ODM that built this Dell mainboard. The name does not say whether the package contains BIOS, EC firmware or both. Technicians use such files to restore a dead board by writing the flash chip with a programmer. Back up the existing contents before writing, and make sure the image size matches the chip installed on the board.
