BIOS dump for the ASUS E402SA laptop on mainboard revision 2.1, supplied as a 7.23 MB RAR archive. The name notes the dual-core Celeron N3050 configuration, which tells you which CPU build the image was taken from. Such a dump is normally written to the SPI flash with a hardware programmer such as a CH341A when the board will not boot or the firmware is corrupted. Read and save the original chip contents first, confirm the revision on the PCB, and make sure the extracted image size equals the flash capacity.
