BIOS archive for the ASUS X556UV laptop, mainboard revision 3.1, labelled as a working dump confirmed in use. The 10.9 MB RAR is intended for restoring the flash chip of a board that powers on without image, beeps, or stopped after a failed update. Flash it with an external SPI programmer rather than through the operating system, and dump the original chip contents beforehand so serial and licence data can be recovered. Make sure the revision on the PCB reads 3.1 and that the image size equals the flash chip capacity.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
