Firmware dump in FD format for the Acer Aspire 5253, 2 MB in size, which fits a 16 Mbit SPI flash chip on the board. The name carries no revision or board number, so treat it as a generic image for this model and verify the motherboard fitted. Repair technicians load FD files into programmer software and write them directly to the chip to fix boot failures caused by corrupted BIOS. Before erasing, read the original chip twice and compare both readings to make sure you have a good backup.
