Clean BIOS dump for the ASUS A455L on the X455LD main board, revision 2.1. The word clean usually means personal data such as serial and system identifiers or the Management Engine state has been reset, though the name does not say exactly what was cleared. At 8 MB it suits a 64 Mbit SPI chip and is programmed with an external flasher. Check the board revision on the PCB, keep a copy of the original contents so serial and MAC information can be restored, then write and verify the image.
