Firmware dump for the Acer Aspire 4720Z, sized at 1.05 MB and stored without a file extension. The name carries INTL, WD and HBM tokens, which appear to mark an international build and an HBM variant, though the name does not explain them further. Because the size is slightly larger than a standard 1 MB flash, check whether a header or padding has been added before programming, and trim it if needed. Always back up the existing chip and verify the board matches your 4720Z before writing anything with an SPI programmer.
