Original BIOS dump for an L412 model, a 4 MB binary corresponding to a 32 Mbit SPI flash. The orig note indicates a read from a factory chip, preferred when restoring a board to stock firmware. The board number is not stated, so check the PCB before flashing. Technicians write such images with a hardware programmer to fix boards that power on without display or fail after a bad update. Read the current chip first and verify the written data afterwards.
