Firmware dump for the A455L / X455LD main board, revision 2.1, marked Clean, which normally means the Management Engine region or personal data has been reset so the image can go onto another board. Packed as a 3.37 MB RAR archive. Technicians use such a dump to recover a dead or corrupted BIOS by reflashing the SPI chip with an external programmer. Compare the board revision printed on the PCB, back up the existing chip, and verify that the image size matches the chip before programming.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
