BIOS file for the ASUS X512JA laptop, labelled F1.305 on board revision 2.0, supplied in a 5.20 MB ZIP archive. The F1.305 token most likely refers to the firmware version, while REV 2.0 identifies the mainboard revision that should match the PCB marking. Technicians flash such images onto the SPI chip with a programmer to fix a notebook stuck on a black screen or boot loop. Back up the original chip before writing, since it holds the serial number and product data, and ensure the image size equals the chip capacity.
