Clean BIOS dump for the ASUS A455L, listed as X455LD main board revision 2.1, 8 MB in size. Clean usually means the image has been prepared without the previous owner's personal data, such as serial or system identifiers, and may need those entered afterwards. It is intended for reflashing the SPI chip with an external programmer when the notebook fails to post or loops. Check that the PCB shows Rev 2.1, keep a backup of the existing chip, and verify the write after programming.
