BIOS package for ASUS notebooks named Y582L and X550LD, both linked to a mainboard revision 2.0 according to the name, packed in a 3.29 MB RAR. No board number or firmware version is listed. ASUS boards of this generation often need both BIOS and EC data, so check what the archive holds. The dump is used to reflash the SPI chip with a programmer when the laptop will not boot or display. Verify the model and revision printed on the PCB, back up the existing chip, and make sure the image size is correct.
