BIOS image for the ASUS UX390UAK ultrabook mainboard, revision 1.2, reported as working and packed as a 6.89 MB RAR archive. Use it to recover a laptop with corrupt firmware by programming the SPI flash chip with an external programmer, often with a clip on the chip. Read the existing contents first and keep that backup, since it may contain the serial number and other unique data, and confirm that the board revision printed on the PCB is 1.2 and that the image fits the chip.
