Zipped BIOS for the ASUS B53J business notebook, B53 mainboard revision 2.0, about 4 MB in size. Technicians use a dump like this to reflash the SPI chip with a programmer when the laptop powers on without display or fails to post after a failed update. Check that the revision printed on the PCB reads 2.0 before writing anything. Back up the existing flash contents first so serial numbers or other unit data can be recovered, and make sure the image size matches the chip.
