BIOS firmware for the ASUS UX305UA motherboard, revision 2.0, which the name reports as tested OK, supplied as a 6.97 MB RAR. A dump like this is used to restore a ZenBook that fails to boot, shows no display or loops after a bad update, by writing the SPI chip with an external programmer. Before flashing, read and keep a copy of the current chip, check that the image size matches its capacity, and confirm the board revision printed on the PCB is 2.0 to avoid mismatched firmware.
