BIOS dump for the ASUS S406U and X406UA laptop on mainboard revision 2.2, in a 5.63 MB RAR archive. Images like this are written to the SPI flash with a programmer to recover a board that stays dark after power-on or loops at startup. ASUS revisions can differ in memory and component population, so confirm that the PCB shows revision 2.2. Read and store the existing chip contents before erasing, and check that the image size inside matches the flash capacity.
