BIOS for the ASUS GL552VW, revision 2.1 mainboard, intended for an 8 MB flash chip according to the name, compressed in a ZIP of about 3.83 MB. An 8 MB image corresponds to a 64 Mbit SPI device, so check the marking on your chip before writing. Technicians use such dumps to recover boards stuck with no display or a boot loop caused by corrupt firmware. Save the original contents with your programmer first, confirm the revision 2.1 marking on the PCB, and verify the write.
